Specialized S-Works Enduro 650B

Specialized has their big wheel game dialed, so rather than hopping on the marketing bandwagon, they chose to sit out the tweener arms race. With the exception of a few gravity oriented models still available in 26″, they stood firmly behind their “bigger is better” mantra, until earlier this year when they quietly released an updated version of their Stumpjumper Evo platform.

The new phrase in town is now “bigger is better – except when it’s not” (what’s currently trendy.) Because despite the sharp handling of their 29er mountain bikes, there will always be a group of riders who consider the wheels size less fun, or too big, or for whatever reason prefer smaller wheels.

So for those consumers, the Big S has released an updated 650B Enduro.

To make this bike available in time for the new model year, Specialized chose to double the utility of their graphics department by giving both the 29er and 650b models shared paint jobs.

For their first entry into the  the 650B market, the Stumpy Evo, they utilized a 29er front triangle with a tall crown race to adjust the angles, but this Enduro utilizes a 26″ front end, and gets a completely new rear swingarm and seatstay strut to achieve the correct geometry.

All of the new complete Enduro 650B offerings will only be available with 1x drivetrains.

This Enduro 29er had chain stays that are 5mm longer than the 26″ model, and the 650B bikes have chainstays that are only 3mm longer than the previous iteration.

Further changes to the geometry include a headtube angle that is one degree slacker, a top tube that is roomier, a slightly lower BB, and a steeper seat tube angle for climbing. The 650B model is also roughly half a pound lighter than the the comparable 29er version.

All told, the bike will be available at four different price points. The top of the line carbon S-Works model pairs the excellent Rockshock Pike with an Inline Cane Creek DB Air Shock, a SRAM XX1 Drivetrain, the new Carbon Roval Traverse Fattie Wheels, and an array of other in house components. Price is $9,300 USD.Enduro Expert Cabron 650BExpert

The Expert model shares the same carbon front triangle and suspension as the S-Works model, but shaves the price by utilizing a SRAM X01 drivetrain, alloy wheels, and more budget friendly cranks. Price is $6,600 USD.
Specialized Enduro Elite 650BElite

The aluminum Elite model has Pike RC internals to shave costs, an X1 drivetrain, and shares much of the remaining component spec with the Expert model. Price is $4,900 USD.
Specialized Comp Enduro 650BComp

The Comp also uses a Pike RC, but swaps out the the Inline CCDB Air for a budget Fox Float Shock. The drivetrain and wheel duties are shared with the Elite model, but a dropper post does not come standard. Price is $3,600 USD.

All frames are available in a Small, Medium, and Large. Taller riders will find their needs better accommodated by the Enduro 29er, which is available in a Medium, Large, and Extra Large.

Stay tuned to Specialized for more info.


  1. Oh my god @Brian, then the Expert is not in your fiscal wheelhouse. That’s what the Elite and Comp are for, consumers like you who whine that they can’t afford the too tier stuff.

    “The Bugatti Veyron is ridiculous. Why can’t they make it that so the common man can afford one,” says every person on Earth except Bill Gates and Mark Zuckerberg.

  2. Link some bikes you can purchase from brick and mortar shops that are comparable to the Enduro with an XX1 group for $6600.

    Comparable meaning carbon front triangle, Pike RCT3, CC DB, comparable travel, etc.

  3. I like the boast about the stays being ‘only 5mm longer’ – given that, via my own measurements, a 650b wheel is only 9mm larger in radius than a 26″, that means they’ve effectively only found 4mm over the 26″.

  4. @timmy, not sure where you got your numbers from, but the diff between a 26″ and 650b rim is 25mm (ISO). So the radius difference would be more like 12.5mm, not 9mm.

    “Only 5mm” longer means it’s 7.5mm shorter than it could’ve been, all other things being equal. With today’s larger volume tires making it even harder to keep stays short, unless you think the stays were long on 26″ Enduros before, I’d argue it’s significant, in that the geo is the primary factor for good handling. Considering how pretty much every bike brand has figured out how to make a 26″ wheel bike handle really well, it’s only natural to want to make a 650b bike handle similarly. I’d say “only 5mm longer” is pretty great.

  5. A good carbon Canyon strive costs about 4000 euro… With lot more to offre and dedicate geometry. Why Specy must keep prices so hi? With simply spec update?? And new wheel? Hope to find a 2014 26″ enduro and nave a deal!

  6. @Gromit & everyone else. If I’m reading this correctly the 650B’s are only 3mm longer than 26″, Correct? And 29″ are 5mm longer than that? Sentence structure up there left something to be desired.

  7. The 26 S Works Enduro is my overall favorite mtb. But… now that the new Ibis looks exactly or quite alike anyway, like the Enduro l would need to re evaluate my dream bike.

  8. @Gromit – ISO measures rim diameter, not wheel diameter including tyre. I measured all three sizes with the same model rim (although obviously different diameter) and the same model tyre (Spec Ground Control 2.3″ if I recall correctly) and found only an 18mm, real life difference in diameter.

  9. Does anybody remember that interview with a Specialized spokesperson at Sea Otter quite awhile ago when they said 29ers are just a niche and will never take off?

  10. spiritofendÚro, I’m sure you’r right about the Canyon and if Canyon bikes were available in the US I’d be all over it!

  11. It’s a Specialized, each and every basher out here want one. Smart choice in bringing in the Elite,but the Expert is still the best bang for the buck.

  12. And for those of you talking about Canyon : only 2 years warranty on the frame and Canyon must evaluate the damage before replacing it,if they’ll do replace it give them one to 4 months.

  13. @Sharden I don’t know exactly but quite any company gives 2 years warranty on carbon frames. Lapierre, Canyon, Radon… What I mean is that if you compare specs you guess that the entry level Enduro is less appealing than other newer bikes and most of all it’s an old frame design, I guess it’s an excelent performer but at that prices you expect at least a little aesthetic enhancement compared to a older model. If you’re lucky enough you can now find a Enduro alu 26 at less than 2500 Euro. But without a remote drop post (the new entry level is like 3200+ €…) . A Brand new entry (but not so entry…) level Lapierre Spicy is about 3300 €.
    I speak for European market, maybe in USA things are really different.
    Radon bikes give 5 years warranty on carbon frames. Just saying.
    I was waiting to see what ’15 Specy Enduro 650b would have been but I must say I am disappointed due to the very little difference compared to the former 26. A little spec change and a wheel swap is not what you can espect from a big company like Specialized.

    “For their first entry into the the 650B market, the Stumpy Evo, they utilized a 29er front triangle with a tall crown race to adjust the angles”

    Can you validate this information? Geometry charts listed on Specialized.com disprove your statement.

  15. @vulgar bulgar

    Yes that is a spacer below the head-tube, my question pertains to the statement made on this article that Specialized recycled their 29er FSR frames for the 650B models.

    Geometry specs show different frames for 29er and 650B Stumpjumper FSR’s



    If this is correct then the article is misleading and it should be edited to reflect accurate information and not speculation.

  16. @A

    While the original assumption that the Stumpy Evo 650b was using a 29er was speculation due to that spacer (which we stated in our article), Specialized refused to comment at that time.

    BUT, the company has now acknowledged their re-purposing of front triangles on both this 650B Enduro, and the 650B Stumpy.

    …So no, the article is not misleading.

  17. @Saris Mercanti

    So the fact that you can remove the spacer, use a longer travel fork, AND maintain the same geo is a feature and not a bug?

  18. Regarding the Canyon bikes, 4200 Euros is ~5700 US dollars. It’s cheaper than the Specialized model, but Specialized doesn’t sell direct to consumers. If Canyon can come to the US and keep their pricing structure and sell direct, they will take a big slice of the market.

What do you think?
