This is the easy handling on anything setup. I would choose it as a confidence booster for more difficult trails. 29 rolls better, which saves considerable amounts of energy on long rides. How much wider? 2.7-3.0in about covers it. They usually sit on wider rims too, 40-50mm internal width to allow the wider tyre to spread out properly and form the optimal shape. Those 27.5in Plus tyres near enough match up in external diameter to 29in tyres, which means some bike companies let you switch between the two wheel sizes. Bigger/Taller wheels..hold momentum better, roll over tire grabbing stuff better.. Two equal wheel builds, same parts, the 27.5 wheel will be obviously lighter and stiffer by design and the 29er will flex more, so better 29er wheels will give you so much more IMO than a level down In 27.5 wheels. What is happening then to the bike market? Well looking back to the Pinkbike testing that we did back in November 2012, it was clear that the 27.5″ bike felt smoother on the same trails compared to a 26″ bike. In corners the 27.5″ required more readjustment to ride as it was slightly more sluggish to put into the corners than a 26″ bike. 6. In theory, a smaller wheel is stronger than a bigger wheel if hub and rim section are the same. This is largely due to the length of the spoke and it's contributions to the stiffness/flex vs spoke braking force. Whether the difference between a 27.5 wheel and a 29 wheel is in of itself enough to mean a real world differe, I don't think so. kD3WgvC. Loudestpipes. • 4 yr. ago. I'm 6'2" and have both 29er and 27.5 for my Scott Genious. The differences are exactly as you stated, however, I'd add that the 29er gives about 6 mm more ground clearance over the 27.5. For me, the add'l ground clearance yields less or no pedal strikes for the 29er. Although this is not a very big deal, when I have It is true that 26 inch wheels which were once a standard feature in mountain bikes are now almost impossible to find. At least not on adult bikes. They are still quite common on children’s bikes but 27.5 and 29ers have become standard for adults’ mountain bikes. What is happening then to the bike market?

In corners the 27.5″ required more readjustment to ride as it was slightly more sluggish to put into the corners than a 26″ bike. There is a reason why road bikes and XC mountain bike racers use this size wheel. 2: Standard 26 inch mountain bike wheels. This was just about the global common standard mountain bike wheel and is found on bikes all over the world. It was by far the easiest size to pick up spare tubes, spokes and tyres in remote places. To get a similar handling feel to your 26" Ruffian you would keep your head and seat angles the same, the same axle to crown on the fork, and same top tube length. Then increase fork rake from 39mm to 42mm to get the same trail figure for steering feel. 26 bead seat diameter is 559mm; 27.5 bsd is 584mm. So that's a difference of 25mm at the rim TimoA. 246 posts · Joined 2014. #9 · Jul 19, 2018. Fuel EX 27.5+ has 2.8" tyres, a 140mm 29er fork and the Mino Link flip chip at the high position. With a 27.5 fork you probably would need to go up to 160mm to get a similar axle to crown length. P.
