Youwill find that 27.5” rims and 29” rims measure 584 mm (23”) and 622 mm (24.5”) respectively. The actual outside diameter of your wheel will depend on the tire Ans: Yes. 29er rims have the same diameter as 700c ones. What you do have to be careful about is the width of the tire. You may need to change the tire to a road friendly one as road bikes have low clearance. The tires may get stuck on the frame of the bike. Another thing you have to keep an eye out for is the brakes. Im interested in the total diameter of Nobby Nics: 29 × 2.25 27,5 × 3.0 But a 29+ is much more expensive than a 27,5+ one. So if I could get approx the same total diameter (wheel+tyre) like on a normal 29er then 27,5+ would be fine for me. Save Share. Reply Quote. 1 - 20 of 26 Posts. 1 2. Inreaction to these ungainly early 29ers, some riders wanted a mountain bike wheel size that offered some of the 29-inch wheel’s rolling benefits and enhanced grip, Theseare 29″ MTBs, where the 29″ is the diameter of the wheels these bikes use. The wheels are also the same diameter as a 700c road bike wheel. Above all, the riding experience of a fat bike vs. a 29er is one significant difference. The former adds weight and resistance while you ride, and as previously discussed, will require more .
