[Closed] Does the boost axle standard mean you can fit wider tyres?

Not necessarily. Tyre width is also dictated by chainline and frame clearance. There are Boost frames now that still won't accept anything larger than a 2.4" tyre.

So is 650b+ the same as boost?

No. 650B+ is a tyre/rim width. The two are often linked as you MAY need Boost if you want to fit wider tyres and rims - say anything larger than 2.8".

Boost also creates a stiffer wheel. Some say this is a good ting for 29ers

Thanks, because I've bought a bike with boost, so its just a wheel strength thing then.

Could be.

I guess that, from a manufacturers pov, it's easier to have one axle size that takes both wide and narrow.

What bike?

has some useful info, there's no point in me re-typing anything out 😀

The new Trance 2, it's my first foray outside of anything with Carrera on it lol.
