I'm ready to build a new wheelset for my Velo Orange Piolet, but I'm struggling to decide between 27.5+ or 29" rims.
The frame is optimized for either 29 x 2.3 or 27.5 x 2.8 tyres. Currently running 29ers but I would like to try 27.5 for the first time for that extra volume, especially to take it off road.
Only thing is I do ride it in town a lot and I might be wrong (?) but I don't see many fast all-road/gravel tyre options in 27.5 x 2.8. I think going smaller would drop the BB and change the ride quality. Would this be noticeable? Do these tyres actually exist? Or is 27.5+ strictly an mtb domain? I'd also like to try tubeless to drop some more weight.
I'll need to fit mudguards for winter commuting duties and I have no idea which would be better for clearance / compatibility. I would have to go smaller than 2.3" to fit guards on the current 29er wheels, so I guess I'd be dropping the BB on either size anyway.
Was hoping someone with more experience with this could help out. I'm confused :/
