    650b fork on Carbine 26"?

    Hope you guys can help me

    I am running my Intense Carbine in 26", and have been using a 2012 Fox 36 talas.

    I would like to upgrade the fork to the new 2014 fox 34 talas, but would like to know if it would be ok to run the a 650b version of the fork using 26" wheels for a lil while, until I get enough cash to the do the whole 650b conversion (wheels, tyres, drop outs etc)?
    what impact would this have on the handling of the bike as I am assuming the 650b fork will be taller?

    Thanks

    a 160 34? i went from a 55 to a 650b 150 rev. a2c on both is ~540mm. a 150 34 should keep the a2c close, the only "drawback" will be some added arch clearance.

    Yeah was hoping to get a 160 34

    Wonder if the new Talas is internally adjustable so I could lower it to 150mm til I get 650b wheels or do you guys think 150mm is plenty for 650b??

    You could also do it the reverse way: slap a 650 front wheel on your 36, and ride that for a while before swapping out the fork. Then you'd get a good sense of how a 650 feels on the bike before investing in a new fork. Just make sure the hub is convertible to 15mm...

    Lbs are now telling me Fox disti is saying that I can't run a 26" wheel in a 650b fork? Anyone know why this wouldn't work? I can't see why it wouldn't

    That doesn't make any sense.

    This seems like good idea too. Getting a new fork and running your old wheel in it till you get a new one. I might have to do this.

    Your 36 TALAS will work perfectly with 650b wheels, even with the bigger 2.35 tires. I ran a Fox 36 Float with 650b for 2 months until I could the new Pike came out, plenty of clearance. All of this on an Intense Carbine. Why not get the wheels tires first then save for the fork? If you have you're heart set on a 34 TALAS then the A-C is 555mm and it's not internally adjustable like the Float. Your 36 should be 545mm A-C so only 10mm different. I'm running the Pike 150mm which is 542 A-C and it's spot on with the Carbine with 650b wheels. I did run the float at 555mm A-C (mine was a Float 180 so started life at 565mm A-C) and felt it was too tall personally for the Carbine. May be fine with a TALAS since you can reduce travel for climbing then open up for DH. Personally, I don't think you'll find the 34 TALAS much of an improvement over your 36 TALAS minus saving only a little bit of weight while losing the stiffness of the 20mm axle. Going from the Fox 36 Float 180 to the Pike I lost 1.25 lbs, had I had the traditional Fox 36 Float to start with I may never have purchased the Pike.

    Great informative post, thanks Kburati

    You don't think the dampener in the new 2014 talas will be an improvement over the either too stiff or too divey 2012 talas?

    Generally the too-stiff/too-divey problem arises with too-linear an air spring, so the damper may be of little help. Perhaps you can shim the air spring in the 36, however, to reduce volume and increase progressiveness.

    For reference, Push is selling volume-reduction kits for Trek's DRCV: Push Industries - Trek Bicycles DRCV Volume Tuning Kits

    So, Chuckie, did you do it? After riding my Lyrik last w-e, me wants to upgrade my 11 Revelation. I'm contemplating getting the 650b 2 step Pike and running the current 26" wheel in there for a while, so the feedback would be welcome.
    Faster is not always better, but it's always more fun

    In the end I just decided to go ahead and update the whole bike to a 2014 Carbine 275

    When I first built my Carbine I ran a RX 2 pos RVL 120-150 27.5 fork with 26" wheels and dropouts. I only did this while I was waiting a month or so for my ENVE 27.5 AM's to land. It rode just fine. Not an ideal setup of course, but still rideable. I wouldn't advise running 26" wheels with 275 dropouts as the BB will be super low.
