Wheels are possibly one of the biggest upgrades you can make to your bike. A lighter pair of wheels will make your bike accelerate quicker as there is less 'rotating mass' to get up to speed. Many of the high end mountain bike wheels we sell are all mostly UST/tubeless compatible as well which means you can completely elliminate pinch flat punctures. You don't have to spend a fortune on a pair of wheels to make a difference though, we have wheels starting from only £19.99!
