Can this bike accept 700cc tires?

Asked by: KTO2017
Yes! According to the DB rep, the entire Haanjo line is made to accept either 27.5 OR 700c/29" wheelsets. I am not getting a clear answer as to the widest tires it will run, but here is the latest reply from Reinout at Diamondback "All Haanjo Carbon frames are the same and will run 700 or 29" wheels. I stand corrected on the tire width. it will handle up to 45c on most tire brands." he first misinformed me to say it could go as wide as 50c, which is not accurate. Not very cost effective to produce mulitple carbon Haanjo framesets, so whichever model you get can swap rims and tires rather easily. I would prefer a 2x10 and 29'er x 2.0 frankly, and as cool as bar end shifters are, they're not practically when climbing something steep. I bet it hurts should your knee make contact too. but the olive frame color is pretty cool.

Can this bike accept a 27.5+ tire?

Asked by: AdventureRider
This bike cannot accept a 27.5+ tire. There is not enough clearance between the blades of the front fork and seat stays.

What rear rack would you recommend for this bike

Can this bike accept fenders with the existing 2.1" tires? Or are smaller tires required in order to fit fenders front and back? Thanks.

Asked by: BikerBuddy
This bike can accept fenders. Based on the tire size, we recommend going with mountain bike fenders. https://www.rei.com/c/bike-fenders

Is it possible to upgrade to hydraulic disc brakes and a more integrated shifter on this bike? Will it be prohibitively expensive?

Asked by: LentheM
Our warehouse cannot make changes to bikes, but our in-store bike shops can speak to the cost of changing-out parts. Contact your nearest REI store for details: http://www.rei.com/help/return-policy.html
