[#9316078]

Hello everybody

I used to have a half decent grasp of part compatibility, well, at least up to 1998!

I have a 27.5+ wheeled (non-boost) Marin Pine Mountain 1 that I want to buy some skinnier rimmed wheels for.

Then I’ll be able to run it as a semi fat adventure bike on one set and a much more economic to pedal on the roads bimble-pub bike on the other but retaining all the pannier racks etc.

I know cassette wear will be uneven but it’s not got many miles on it and I’m unlikely to do that many more so I think the chain will survive the occasional wheel swap!

Question is do I buy 27.5 wheels or 29’er?

I ask as I’m sure I read somewhere that a 27.5+ tyre’d wheel actually equals a standard tyre’d 29’er wheel in terms or diameter.

Do people think that’s correct or bo**ocks?

B+ compatible frames are usually marketed as B+/29er frames, so you can run both in virtually all of them.

Should be fine, might have clearance issues if your 29er wheels have big (2.4/2.5) tyres but in general shoudl work fine - 29ers are a little bigger generally, about a half inch in diameter

They're not the same diameter but most B+ frames will take a 29er wheel, especially if you're meaning 29x2.1 rather than 29x2.4. The BB will be slightly higher but it's unlikely this will cause you any problems. Just swap the cassette over when you want to change wheelset, and maybe re-centre your disk calipers. The latter can be minimised if you use the same type of hubs and rotors.

Excellent feedback as always team singletrack!

Good point re-rotors too.

I'll be looking to run significantly narrower than 2.0.

Is there an issue going to hybrid tyre width?
