Abike frame is specifically designed around the wheel size it uses. So you couldn’t buy a 29er and decide to slap 27.5 wheels on it instead. This independent design process means that a 29er bike won’t be much–if any–higher off the ground than a 27.5, so standover height shouldn’t be an issue even if you’re a shorter rider.
Acceleration27.5 in. wheels have faster acceleration while 29ers are more efficient on longer rides. Smaller wheels accelerate faster than larger wheels. This is due mostly to where the weight of the wheel is distributed.
AccelerationWhen it comes to getting out the blocks fast, the 27.5” wheels are much better at accelerating than 29” wheels. The 27.5” wheels are smaller and lighter, and getting them up to speed is much easier.
275-inch wheels are typically quicker to accelerate when compared to 29ers, which is mainly a result of their lower weight that requires less effort to spin. This can be
Mountainbike wheels come in two sizes: 27.5 inches and 29 inches. Back in the day, MTBs had 26 inch wheels, though this has all but died out now. If you decide you want a mountain bike, we recommend taking a look at our article on 27.5 vs 29er MTBs. Contrary to road bikes, mountain bikes have wide rims for wide and chunky tyres.
