A £149.99 Scottish bib short keeps beating rivals that cost twice as much. Men's Fitness named it "comfiest on test" in its March 2026 roundup, and OutdoorGearLab still has it in the 10 best cycling shorts of 2026. This is our full, current review of the Endura Pro SL bib shorts: what changed in the 2026 range, what the independent test data actually says, which size to order, and how they stack up against Assos, Rapha and Castelli. Every price and verdict here was checked against 2025–2026 sources, so you're reading about the shorts as they exist today, not the three-pad-width version reviewers tested five years ago.

The short answer for skimmers: the Pro SL EGM is still the comfort-per-pound benchmark at £149.99 RRP ($219 USD). With street prices dipping as low as £96.49, it might be the best value in premium bib shorts right now, full stop. Three honest caveats, though. The shorts run small. The EGM version dropped the old pad-width options. And the straps come up short if you have a long torso. Everything below unpacks those three points with data.

Key takeaways

- Still the benchmark at the price. Men's Fitness (Mar 2026) called the Pro SL EGM "comfiest on test"; verified buyers average 4.89/5 and say the chamois "outperforms more expensive bibs."

- Two current models in 2026: the Pro SL EGM (£149.99/$219, 800 Series Conform EGM gel pad) and the new range-topping Pro SL Power ($250/£199, 700 Series high-density pad, Power Lycra fabric).

- They run small. Between sizes, or coming from US-fit brands? Size up. Official waist chart and buyer-verified guidance below.

- Street prices are the story: the EGM has been tracked at £96.49 in the UK and $127.99 at Bikeinn, roughly 35% under RRP since the Power launched above it.

- Risk-free trial: Endura's 90-day satisfaction guarantee means you can ride them and return them if the pad doesn't suit you. No flagship rival offers this.

What's New in 2026: The Pro SL Family Explained

The single biggest source of confusion in every Endura Pro SL review you'll read is that "Pro SL" now means three different shorts, and most reviews only cover one of them. So let's sort that out first.

The current range has two live models. The Pro SL EGM Bibshort is what Endura calls "the latest evolution of the game changing Pro SL Bibshort," built around the new EGM pad at a UK RRP of £149.99 ($219 USD). Above it, new for the 2026 season, sits the Pro SL Power Bib Shorts at $250 USD / £199. That one is a genuine range-topper: a 700 Series high-density pad, a "Power Lycra" knit fabric, three colourways (Black, Ink Blue and the tartan-inspired Kilt Rock), sizes XS–XXL, and two leg-length options. Both carry Endura's 90-day satisfaction guarantee.

Then there's the ghost in the range: the previous-generation Pro SL (often labelled Pro SL II), the version that made the line famous. It came in five sizes and, crucially, three pad widths (narrow, medium, wide) chosen via an online sit-bone fit tool. road.cc weighed the Lite variant at just 199g. That model is now clearance stock; on Endura's EU store it was listed at €180 regular price, on sale at €126 as of February 2026, while the Power sat above at €230.

Which one should you buy? A quick decision rule we use with customers:

1. Most riders, most budgets: the Pro SL EGM. It's the model winning the 2026 group tests and it's heavily discounted right now.
2. If you want the newest, firmest, most supportive pad and race-day fabric, pay for the Pro SL Power. It costs roughly £50/$30 more and gets you the 700 Series high-density pad and Power Lycra.
3. If you loved the old sit-bone-matched pad widths, hunt down previous-gen clearance stock (from €126) before it disappears. The EGM's one-pad approach genuinely doesn't suit everyone.

The 800 Series Conform EGM Pad: What the Tech Actually Does

The headline technology in the current shorts is the 800 Series Conform EGM pad, an evolution of Endura's previous 700 Series chamois. The functional difference is the insert strategy. The EGM pad places medical-grade silicone inserts at the contact points where sit bones and soft tissue load the saddle hardest. A conventional chamois relies on foam densities alone; the gel inserts are positioned to hold their shape and damping under sustained load.

Does it work outside the marketing copy? The independent evidence says yes. Cyclingnews tested the long-leg EGM version in Mallorca, at temperatures of 25°C/77°F and above, on multi-hour rides, and found it "really comfortable on short and long rides." Verified buyers on Bikeinn average 4.89/5 across reviews and repeatedly say the chamois "outperforms more expensive bibs." Several credit the reduced seam count for less chafing.

Now the honest trade-off, because it's the one thing Endura's product page won't tell you. The old Pro SL came in three pad widths, matched to your sit bones via an online measuring tool. Reviewers loved that system. The EGM replaces it with a single gel-based pad. There are no pad-width options on the EGM model, full stop; retailer Q&A threads confirm it. For most riders the Conform pad's shape-adaptive design covers the range well. But if your sit bones are unusually wide or narrow and you previously used the "wide" or "narrow" Pro SL pad, you have two options: the Power (a different, high-density 700 Series pad that some riders with firmer preferences will actually prefer) or clearance stock of the old model.

Key takeaway: the EGM pad is a real comfort upgrade for the middle 80% of riders. The 90-day guarantee (more on that below) exists precisely so the other 20% can find out risk-free.

Comfort on the Road: What Independent Testers Found in 2025–2026

We lean on named, dated third-party tests here rather than our own impressions. A review you can audit is worth more than one you have to trust.

The long-ride stress test. OutdoorGearLab put the Pro SL through an 8-hour ride with 7,000 feet of climbing in Oregon's Elkhorn Mountains. Their tester stayed comfortable for six hours of it, and the verdict was blunt: "high-performing, durable, and comfortable… worth the money." Read that six-of-eight-hours figure carefully. It's a genuine endorsement, since six hours of pain-free riding covers a century for most of us. It's also the product's honest ceiling: on the very longest days, the chamois compressed noticeably toward the end.

The heat test. Cyclingnews rode the long-leg EGM through Mallorca sessions at 25°C+ for hours at a time and reported real comfort on both short and long rides. That matters if your worry is a gel-insert pad turning into a heat trap in summer. The high-wicking rear yoke panel earns its place here.

The build-quality audit. Cycling Weekly's review, the one titled "range-topping quality for a lower price than usual" at $219/£149.99, praised exemplary stitching and finish, a "super-comfy" chamois, and quality leg grippers and bib straps.

The crowd. Bikeinn's verified-buyer average of 4.89/5 is remarkably high for bib shorts, a category where sizing and pad-fit complaints usually drag scores down.

And the criticisms, because a review without cons is an advert. OutdoorGearLab found the straps ran about an inch too short for a long-torsoed tester, and the high waistband could press uncomfortably over the belly; their 2026 roundup also notes the "medium and large chamois can gather" on some models in the line. Cycling Weekly flagged that the shorts run small and that Endura "lacks sustainability focus" compared with some rivals. None of these are deal-breakers. All of them are things you want to know before clicking buy.

Fit and Sizing: They Run Small — Here's Exactly What to Order

This is the highest-anxiety part of any bib-short purchase, and it's where competing reviews are weakest. Most say "runs small" and move on. Let's fix Endura bib shorts sizing properly, with the official chart plus real buyer outcomes.

Endura's official men's size chart, by waist measurement:

The full EGM range runs XS–2XL. The chart alone isn't enough, though, because multiple recent buyers report the Pro SL EGM runs small against its own chart. One reviewer who normally wears L found the XL fit perfectly. Another described the cut as European sizing, "very much the same as Castelli or Santini in medium, just a little looser," and explicitly tells US-sized buyers to go up a size. OutdoorGearLab reached the same conclusion from the other direction, recommending you try before buying because "your normal size may not be what you want to choose."

Our sizing decision checklist. Work through it top to bottom and stop at the first rule that applies:

1. Coming from Castelli or Santini? Order your usual size in those brands. The Endura cut is nearly identical, marginally looser.
2. Coming from US-fit brands (Pearl Izumi, Specialized, generous club kit)? Size up one.
3. Between two sizes on the waist chart? Size up. Every buyer report points the same way.
4. Long torso? The straps run roughly an inch short. If you're long-bodied and between sizes, sizing up solves both problems at once.
5. Squarely mid-range in one size, normal proportions? Order that size, and lean on the 90-day guarantee if it disappoints.

Standard or long leg? The long-leg (extended) EGM is approximately 4cm longer than standard and finishes just above the knee. Choose it if you're tall, prefer more muscle coverage, or want a more pro-style silhouette. The standard length suits riders under about 5'10" and hotter climates, although Cyclingnews did its Mallorca heat testing in the long-leg version and reported no overheating penalty.

And the safety net that removes most of the risk: Endura's 90-day satisfaction guarantee. Return within 90 days of purchase, with proof of purchase, for a no-quibble refund or replacement. In practice it works as a 90-day chamois trial. Order your best-guess size, ride it properly, and swap it if you got it wrong.

Durability, Everyday Details, and the Honest Cons

Premium bib shorts are a per-ride cost calculation: a £150 short that lasts four seasons beats a £90 short that's translucent by August. Durability is one of the Pro SL's strongest cards.

OutdoorGearLab's long-term note, after months of use and repeated washing: only "infinitesimal bits of fraying," with the densely woven fabric showing no meaningful wear. Their one care instruction is worth adopting. Hang-dry, never tumble, to extend the life of the Lycra and grippers. Cycling Weekly's stitching-quality praise points the same way; this is a garment finished to last. We've documented this ourselves over a longer window. See our Endura Pro SL bibs 6-months-later durability review for how the leg grippers specifically hold up over half a year of real riding, which is the one long-term question this fresh review deliberately leaves to that piece.

The everyday details are quietly good: a high-wicking rear yoke panel that earns its keep in summer, quality leg grippers that stay put without sausage-squeezing, and three colour options (Black, Deep Teal, Ink Blue) in the EGM.

For balance, here is every con the 2025–2026 test record surfaces, in one table. No single competing review gives you this:

Read the right-hand column against your own body and riding. Long torso plus a preference for low waistbands? That's two strikes; consider the competition below. Everyone else: the left column is what £150 (or £96 on a good day) buys.

Endura Pro SL vs the 2026 Competition: Assos, Rapha, Castelli, MAAP

Here's the money table. These are the 2026 flagship bib shorts a Pro SL buyer is realistically cross-shopping, with current pricing and pad technology:

A few things jump out of that table. The Pro SL EGM undercuts every non-Endura flagship by $11–131 at RRP, and by far more at current street prices. It's also the only short on the list (along with its Endura siblings) carrying a 90-day satisfaction guarantee, which matters enormously in a category where pad fit is personal and "no returns once ridden" is the norm elsewhere. And the benchmark it's chasing, the Assos MILLE GTO S11 chamois with its 14 mapped foam densities, lives in shorts selling for over £200. The Endura undercuts that benchmark by roughly £50–100.

What do you actually give up at the lower price? Going by the aggregated test record: a little top-end pad sophistication on 8-hour-plus days (the Assos Equipe RS and Rapha Pro Team III hold form longer at the extreme), cargo storage (Rapha's Core Cargo at £110/$150 is BikeRadar's under-£150 pick if pockets matter more than pad), and brand cachet. What you don't give up: build quality, tested long-ride comfort to six hours, or durability. If you're assembling full kit rather than just shorts, our cycling jersey buying guide pairs directly with this decision.

Price Check 2026: RRP vs What You'll Actually Pay

Competing reviews skip this section entirely, and it changes the buying maths. Since the Pro SL Power launched above it, the EGM has been discounted aggressively across the market. That's classic behaviour when a brand introduces a new range-topper over a still-current model.

The 2026 price landscape as we found it:

• Pro SL EGM RRP: £149.99 UK / $219 USD.
• UK street: Tredz has listed it around £129.99; price-tracker Idealo recorded a UK low of £96.49 in February 2026, roughly 35% under RRP.
• International street: $127.99 at Bikeinn.
• Pro SL Power: holding firm at $250 / £199. Expect no meaningful discounts on a new-for-2026 model this year.
• Previous-gen Pro SL: €126 on sale at Endura's own EU store (down from €180), while stock lasts.

Buy now or wait? Three questions settle it:

1. Is the EGM under about £120/$150 in your size today? Buy. You're at or near the tracked floor, and sizes vanish from discounted lines fastest at the popular M/L end.
2. Is it at full RRP everywhere you look? You can afford patience. The sub-£130 street price has recurred throughout early 2026, so set a price alert; the pattern says you'll see it again within weeks.
3. Do you want the Power specifically? Stop waiting. New range-toppers don't get discounted in their launch year. Pay the £199/$250 or choose the EGM.

Pro tip: the 90-day guarantee runs from purchase date with proof of purchase, and it applies to discounted stock from authorised retailers too. A £96 pair with a no-quibble 90-day return is about the lowest-risk premium bib purchase you can make in 2026.

Verdict: Who Should (and Shouldn't) Buy the Endura Pro SL

Put together every credible 2025–2026 test (Cycling Weekly, OutdoorGearLab, Cyclingnews, Men's Fitness) plus the verified-buyer data, and the verdict is consistent: the Endura Pro SL EGM delivers flagship comfort at mid-range money, and at current street prices it's the value outlier of the segment. OutdoorGearLab's framing is the fairest one-liner: "near-premium performance without the ultra top-shelf price."

Buy the Pro SL EGM if:

• You ride 2–6 hours at a stretch. That's the pad's proven sweet spot.
• You want group-test-winning comfort without paying Assos or Rapha money. You'll save $60–130 at RRP, more at street prices.
• You value durability. Months of wash cycles with near-zero wear is the best record in this test group.
• You're an M-to-XL rider of normal proportions willing to follow the size-up guidance above.
• You want a safety net. The 90-day guarantee means a mis-chosen pad costs you nothing but postage.

Skip it (and buy this instead) if:

• You need pad-width options. Hunt previous-gen Pro SL clearance stock (from €126) while it lasts, or go to Assos's sit-bone-mapped MILLE GTO S11 chamois at £200+.
• You have a long torso and hate short straps. The strap-length complaint is documented; try before you buy, or look at the Rapha Pro Team III.
• You want built-in storage. Cargo bibs like the Rapha Core Cargo (£110/$150, BikeRadar's best under £150) do what no Pro SL does.
• You regularly ride 8-hour-plus ultra days. The chamois-compression ceiling is real; the firmer Pro SL Power ($250) or Assos Equipe RS S11 ($340) hold form longer.
• Your budget stops at £100. Endura's own FS260-Pro (~£90) is a 2026 UK guide's best-all-rounder pick and keeps the 90-day guarantee.

For most road riders reading this, the first list wins. Order your size (up, if in doubt), ride it for a month, and let the guarantee absorb the risk. You can browse current Pro SL stock and the rest of our cycling apparel range in the Rydecruz collection.

FAQ: Endura Pro SL Bib Shorts in 2026

Are Endura Pro SL bib shorts worth it in 2026? Yes. Men's Fitness named the Pro SL EGM "comfiest on test" in March 2026, OutdoorGearLab calls it "worth the money" after an 8-hour test ride, and at £149.99 RRP (street from £96.49) it undercuts every rival flagship by $30–130 while carrying a 90-day satisfaction guarantee.

Do Endura Pro SL bib shorts run small or true to size? They run small. Endura's official chart lists M at 84–89cm waist and L at 89–94cm, but multiple verified buyers report needing one size up. One rider who normally wears L fit an XL perfectly. If you're between sizes or coming from US-fit brands, size up; the cut is closest to Castelli or Santini.

What's the difference between the Pro SL EGM and Pro SL Power? The EGM (£149.99/$219) uses the 800 Series Conform EGM gel pad with medical-grade silicone inserts. The Power (£199/$250) is the new 2026 range-topper with a firmer 700 Series high-density pad, Power Lycra knit fabric, and colours including Kilt Rock. Choose the EGM for value and proven comfort, the Power for the firmest support.

What is the EGM pad in Endura bib shorts? EGM is Endura's 800 Series Conform chamois, an evolution of the 700 Series that adds medical-grade silicone inserts at key pressure points to relieve sit-bone and soft-tissue load. It comes in one width only; the older three-pad-width system was discontinued with this generation.

Should I get the standard or long-leg version? The long-leg EGM is about 4cm longer, finishing just above the knee. Choose long leg if you're tall or prefer more coverage. Cyclingnews heat-tested it at 25°C+ in Mallorca with no comfort penalty. Standard suits shorter riders and the hottest climates.

How much do Endura Pro SL bib shorts cost in 2026? RRP is £149.99/$219 for the EGM and £199/$250 for the Power. Street prices on the EGM have been far lower: $127.99 at Bikeinn and a tracked UK low of £96.49, roughly 35% under RRP since the Power launched above it.

Is there a guarantee if the pad doesn't suit me? Yes. Endura's 90-day satisfaction guarantee lets you return the shorts within 90 days of purchase, with proof of purchase, for a no-quibble refund or replacement, even after riding them. No rival flagship (Assos, Rapha, Castelli) offers an equivalent ridden-product guarantee.

How do Endura Pro SL bibs compare to Assos? The Assos Mille GTS S11 ($280) and Equipe RS S11 ($340) carry more sophisticated chamois technology (Assos's benchmark MILLE GTO pad maps 14 foam densities) and hold form slightly longer on 8-hour-plus rides. But the Pro SL EGM costs $60–120 less, matched or beat them for comfort in 2026 group tests up to six hours, and adds the 90-day guarantee Assos doesn't offer.
