The Schwalbe Racing Ralph is Schwalbe's most beloved tire. It satisfies the weight weenies, maintains low rolling resistance, and provides great grip.

The Schwalbe Racing Ralph UST Tire uses Schwalbe's Triple Compound technology. Schwalbe recognizes that it's not possible for one compound to do it all, so they've combined three to optimize the tire's performance wherever possible. The low-profile tread of the Racing Ralph is fast, but is an excellent cornering tire thanks to its U-Blocks. A U-Block is a block of tread angled 20 degrees or so towards the outside of the tire. A small sipe doesn't quite divide the block, creating the "U". The U-Block works to counteract the natural outward force the tire is under when cornering, helping to control the forces and keep the bike stable.

The tire is designed to be tubeless (UST), which means you can say goodbye to pinch flats. A tubeless system allows you to run less air pressure, again enhancing the grip of the tire's tread. Better traction, less vibration, and no flats lead to a great ride. We recommend running a bit of sealant within the tire to quickly seal thorn or debris punctures.

The Schwalbe Racing Ralph UST Tire is available in 2.1 or 2.25 widths. 590g (2.1)/650g (2.25). Please note: because Schwalbe has optimized this tire to be lightweight, patching in the event of puncture is not recommended.
