The Hope RX4+ mineral oil type brake caliper has been refreshed as the RX4+ SL. The RX4+ SL caliper retains a precision CNC-machined monobloc design that results in a stiffer caliper to give unrivaled feel and modulation. In addition, it now features a new bore cap that adopts the narrower design first introduced on the GR4 and TR4 to reduce overall caliper width and improve compatibility with a wider range of frames. It now also incorporates the bleed nipple design from the RX2, making bleeding simpler and cleaner. Together, these focused updates make the RX4+ SL more user-friendly while maintaining the powerful, reliable performance riders expect.

Exceptional Wheels
The CLX III are exceptional I was a little apprehensive about buying them having ridden the Enve 4.5 but you feel less crosswinds and their lighter and spin fast. The spokes seemed to offer a lot of dampening vibration. Win win in my book.
Got this for my kids bike. He does XC racing. Has been riding in dry lose dirt, wet conditions. Lots of climbing and some downhill. He loves them. Shipped fast and in sexure packaging. I would definitely buy again.
Heard a lot of good things about this tires put them on my commuter. The roll much faster than the schwable energizers on it. Puncture protection only time will tell.
