Hutchinson 650B 27-5 mountain bike tires offered in Toro Cobra and Cougar with DH MTB tire coming soon

Hutchinson subtly alerted us to their 650B plans at Sea Otter last year, saying the Cobra and Cougar would come in 27.5″ options. Since then, they’ve added the Toro to the mix and just announced that all three are rolling through the supply chain now.

All three will come in Tubeless Ready Hardskin casings in a variety of widths. All are produced in their Montargis factory in France. The Hardskin is a bead-to-bead reinforcement and they also use their Race Riposte triple compound and knob reinforcement. They’ll be available aftermarket first, with OEM options coming soon.

Confirming the notion that 27.5″ is all but perfect for downhill mountain bikes, they’re working on wider, gnarlier variant of the Squale.

Sizes, weights and pricing shown after the break…

Below, the numbers and letters are:

  • WB/FB = Wire / Folding Bead
  • 66 = TPI
  • TT/TL = tube type/tubeless
  • TLR HDS RR = Tubeless ready, Hardskin, Race Riposte

  1. Does 27.5 obsolete the 26? Seriously. My friends in the industry have all but guaranteed that the 29 will live on for XC and 27.5 will obsolete the 26. Curious as to others opinions.

  2. @ Matt

    I was wondering the same thing.

    I’m on the fence about buying a 29″ Specialized Epic but just know that as soon as I did they will come out with a 27.5 that will be the “be all to end all” XC bike.

    If I was looking at a trail bike I know that I would wait at this point, but I’m not for sure on the XC bike.

    Anyone have any thoughts that might help?

  3. @ Watchtower, I would not wait to buy a bike as no one knows how long any new technology will take to catch on – and by catch on I mean having a meaningfully wide selection of parts and components to chose from in the new format.

    I do think the 27.5 is going to be prevelant at some point for two reasons, 1) it rides well and 2) the euros were really behind on the whole 29er focus and they don’t want to miss the next thing – so they will and already are pushing it hard.

    While I think the 27.5 will be super sweet, I just purchased a new Trek Remedy 9.9 (26er) and will ride it hard for the next 3 years at which time, maybe the 27.5 will be ubiquitous enough to look at.

    By the way, the Spec 29er epic is an amazing XC bike. IMO the Sworks version is the best XC race bike on the market.

What do you think?
