    26" 34 Talas 160 CTD 650b compatible

    I have searched and have only been able to find people speculating about the compatibility of this fork with 650b wheels. Has anyone successfully used one with 650b wheels? Thanks!!

    I've searched all over about this and the only definitive answer out there is that you're better of just getting the proper fork for your wheels. If you're going 34 anyway I don't see why you wouldn't want the 27.5 version? The reason I was curious was because I'd kinda of like the more beefy 36, so I was trying to justify stuffing my 650b in a 36. From what I gathered that plan would work, but depending on tire choice there's a decent chance I would need to rock a 10mm travel spacer. That isn't a huge deal really, but I think I'm just going to go for the 27.5 34mm option and enjoy not having any hassles.

    I already have this fork it came on my Mojo HD, which is why I am trying to find out if the 650b wheels will fit on it.

    hi Nate,

    after looking at some pictures I see that F34 has o lot of clearance with 26" tires, we all also know that even f32 cleared 650b tires. I can assume that f34 will take 650b tire with no problem... but when you have a fork already measure it - from axle to arch. 650b tire is 700-710mm tall, right?
    Add roughly another 1cm (~1/2") for mud and it should be fine.

    BTW. if someone can help with a real picture I would be also pleased

    I'm pretty sure it's not the arch clearance but the crown that could be a problem.

    That being said I'd be totally shocked if there was any arch clearance issues since the 32 series clears even the tallest 650B tires by about 3mm. I'd say to let all the air out with your 26" wheels on and slam the fork to the bottom and see how much clearance you get to the bottom of the crown. Your looking for at least 12.5-13mm but hopefully more like 15mm+.

    The 34 fork has a 7mm greater A/C height than the 32 fork (26" versions) so I'm thinking for at least most tires it should be a go. Still, get that measurement.

    Thats a 2.35 Hans Damph on a P35. The clearance there is about 3/8".

    26" 2.35 Hans Damph on a P35?
    3/8" is 9,5mm? (gosh I have these inch measures, they make no sense)


    so it looks like no way with 650b 2.35 Hans Damph, maybe try smaller tire

    Didn't they flatten the arch design on these new generation 34mm forks?. If they did , the cynic in me would say that the changes came about to force people to use the official 650B fork. I suspect however it may have been to tweak up the stiffness , especially since they have dropped the weights of the forks yet again.

    Note the new arch design in these pics, it's quite different.

    Jeez, didn't realize that so you could very well be right. Quite different in the arch area for sure vs previous years.

    Guess we need someone to actually try it and see.

    Interesting and on the same theme but that's a 29'er wheel stuffed into a 34mm 650B fork with 160mm travel.

    If the clearance has reduced on the 34mm forks it looks like the 36mm forks still uses the old fork brace.

    Aren't the fork offsets different angles on these forks as well?

    Yup

    Generally 26" forks have an offset of around 40mm, 650B forks mid 40 range, and 29'er forks 51mm.

    In theory the 34mm 650b float should have more offset?Fox have taken their drawings off their site. I believe the 29er 34mm Floats have been pushed up to 52mm offset? One review of the 34mm 26" 160mm Float said it's offset was similar the 32mm floats. The 36mm Float used to have an odd ball 37mm offset.

    My 55 CR has a 44mm offset which makes it still steer well with a 650B up front.

    "The axle to crown length on a 34mm 27.5 160mm travel fork is 554.4mm with an offset of 44mm. A 34mm 29 150mm travel fork would have an axle to crown of 562.8mm with an offset of 51mm."
