mtb 26 vs 27.5 vs 29
I think that the 27.5+ wheel size platform would be more versatile for everyday trail riding. It is fun and playful. While the 1120 is no doubt a neat bike that can roll over a tree without flinching, it is far less practical for your local MTB trail. 29+ really shines for bike-packing but can be a little too bouncy for mountain biking.
29 rim diameter is 622mm, 27.5 rim is 584mm, a difference in radius of 19mm. So replacing a 29 wheel with a 27.5 with same make of tire, will drop the bike ~19mm. 165mm cranks “buys back” 10mm of ground clearance. In most situations for most riders, ~10mm less ground clearance is negligible. xcerj61 YT 2's & Jeffsy 29er • 8 yr. ago. I don't know the trail, but 27" is generally more stable so it's easier to do large gaps. pinnr • 8 yr. ago. I prefer 27.5, but I'm currently riding 26" because they're still new enough that you can get killer deals on slightly used 2014/2015 26" DH bikes on eBay. The 27.5 inches mountain bike has a wheel diameter of about 698 mm and a rim diameter of 584 mm. After installing an outer tire, the wheel diameter of 29 inches mountain bike is about 736 mm, and the diameter of the rim is 622mm. 26 inches is the most traditional mountain bike wheel diameter.In this wrap up we’ve got: 1) A standard 27.5 tyre mounted to a regular width rim – Bontrager XR4 650b x 2.35 on a DT E1900 rim (internal rim width of 25mm). 2) A standard 27.5 tyre mounted to a super wide rim – Bontrager XR4 650b x 2.35 on an Ibis 741 rim (internal rim width of 35mm). 3) A 27.5+ (or 6Fattie) tyre mounted to a mid-width
Short answer: The 29er will be more efficient, the 27.5 will be more maneuverable. If you want to go fast get the 29er. If you want to huck jumps get the 27.5. YMMV. At 190 lbs you'll have no problem flicking a 29er around. 10. [deleted] • 5 yr. ago. The 29er will be more efficient, the 27.5 will be more maneuverable.
