Open up bike review. Our test bike in detail. Open noted that a 650b rim with a 2 1 inch mountain bike tyre has nearly the exact same circumference as a 700c rim with a 28mm tyre meaning the up preserves the geometry and feel of a road bike. 50mms on 700c wheels a wagon wheel set up that left barely a sliver of daylight. Open only sells the up as a frame and fork set meaning the parts we tried were simply the dealer s choice or perhaps whatever they had in stock.

Test bike features a complete bar stem seatpost enve kit and rolls out on a dt swiss gr 1600 spline 25 and grc 1400 spline 42 wheelset respectively.

But you can also fit a 47mm roadplus tire 40mm gravel tire a 32mm cross tire or a 28mm road tire or anything in between exact tire sizes depend on manufacturing tolerances and rim width so always check and make sure you have 6mm clearance between tire and frame. There s a lot of versatility baked into the open up but the one detail it s arguably missing is the addition of mudguard mounts that would ensure it meets the needs of the all weather british cyclist.
