Shimano RS710 C32 Tubeless Disc Brake Front Wheel
  • £311.99
  • RRP £479.99
  • Saving you £35

The Shimano RS710 C32 disc-brake front wheel is an excellent option if you’re looking to upgrade or replace an existing one on your bike. If it’s a full wheelset you’re looking for check out the RS710 C32 wheelset This front wheel is the Japanese brand’s most affordable carbon, road wheel ever. If you’re on a budget or simply only need a replacement, then this is great option to consider. As with all of Shimano’s mid-tier products, it benefits from the experience the brand has gained from producing their premium Dura-Ace and Ultegra lines. The result is a wheel that’s relatively lightweight—especially considering the price point—yet stiff and offers some aerodynamic optimization. A Sleek Mountain Wheel A front Shimano RS710 C32 weighs a respectable 665g, making it perfect for those days spent climbing in the Alps. You might be able to find a lighter set of wheels on the market but at this price point this represents excellent value. Boasting a sleek, minimalist design this is a stylish hoop in its own right but it’s also subtle enough that you can easily pair it with an existing rear without it sticking out like a sore thumb. A Wider Rim With Better Braking The width of RS710 C32 has a wide rim profile that has been optimised for a 25mm to 32mm tyre. What’s more, the hooked-rim profile is tubeless compatible. The benefit of the extra width is that you can run lower pressure in the tyre. Although it goes against the previously accepted wisdom of using slim tyres pumped up to 120psi, a wider tyre at a lower pressure will be faster. Combine this with a tubeless setup and you’ll also experience fewer catastrophic punctures. As the RS710 C32 front wheel is engineered for hydraulic disc brakes you’ll benefit from enhanced braking power on offer from the latest disc brake technology. In using disc brakes, you’ll be confident in braking, in the wet or dry and on steep and/or long descents.
