bikeny. You can run a 27.5 Plus fork and then swap between 29 and 27+ wheels no problem. Most 29er forks will not fit a 27.5+ tire, not because of the diameter, but because of the width. My Fox 32 29er boost fork (non stepcast) fits a true 27.5x3 tire on i39mm rims with ample room to spare. A 26″ wheel uses a rim with a 22inch/559mm diameter. А 29″ wheel relies on a rim with a 24.5inch/622mm diameter. The radius difference between 26″ and 29″ rims is 63mm/6.3cm/2.48inches. Therefore, if a 26″ wheel and a 29″ wheel use the same tire model, the 26″ wheel will result in a 63mm reduction of the bike’s height. A lot of the high-volume 27.5+ tires actually have a taller sidewall than comparable 29+ tires. This makes them less stable under hard cornering than lower-profile 29+ tires and that extra sidewall rubber adds up. It’s hard to believe, but there are 27.5+ tires that weigh more than some 29+ tires. We measured each front wheel inflated to 10 psi. Here are the numbers taken from 4 sets of wheels to begin to compare 27.5″ wheels to 26″ wheels. A) This is a wheelset that closely resembles the size (rim diameter and width) that have been spec’d as original equipment on most fat-bikes that have been sold for the last five years. (80mm With a regular 29/700c fork, you can use rim or disk brakes, depending on fork. Check the manufacturer’s specifications carefully before you decide which fork to buy! On the 26 inch suspension corrected, you’ll need disk brakes to put a 29 inch wheel. A mountain bike modified in this way is called a 69er. UwBR. Cycling UK’s article about tyre sizes has a handy formula for matching tyre widths to rim widths: the ideal ratio is roughly 1.8 to 1. So a 23mm tyre is just right on a 13mm rim (13×1.8=23.4). If you’d rather not do any maths, Schwalbe has a chart. Tyre and wheel size is also limited by the space available in the bike’s frame, fork and Can I put 27.5 tires on 700c? On 700c wheels, maximum tire clearance on frames usually hovers around 40 mm while frames that can take 650b wheels can then accommodate 2.1″ (53mm) or even 2.2″ (56 mm) tires. Knolly gives you options to run up to 700×45 tires or 27.5×2.1″ on its Cache, and still have clearance for fenders. The size of the tube is usually written on the box. Tubes stretch a bit so they fit a variety of sizes. For a 27 x 1 1/4 tire you would need one that says 700x32 which is the equivalent new size of tube, although both the old system and new system are usually written on the packaging. If you can convert, my opinion is that it is worth it. I converted my Trek Fuel from 26er to 650b last summer and love how it changed my bike. Much better roll-over, slightly more slack front end and just a lot more fun to ride due to being able to use lower rolling resistance tires (most 2.3-2.5 tires that would equal 27.5 are for gnarly The 27.5 version takes up to a 2.8 inch tire and runs out to 170mm. The 29er chassis is spec at 27.5x3 and 29x2.6 up to 160mm. From personal experience, I can say the 29 chassis will take a 29x2.8 inch and some 29x3 inch tires. The MRP Ribbon is an amazing fork.
