We’re sad to say the R725 has been discontinued now, apologies to anyone who missed out!

The latest edition of our ever popular track frame, made with Reynolds 725 heat treated steel tubing. Fully lugged construction and super tight true track geometry gives this frame a Keirin feel which is equally at home racing on the track as it is on the streets. That Keirin influence continues this year with two eye catching paint options – a metallic lilac and black sparkle which really pops in the sunshine!

Other improvements include the polished stainless dropouts and slightly more clearance on the fork so you can now run up to a 28c tyre up front (25c with a brake).
