The lightweight Racelight Tk2 winter training frame has all the proven details of the Racelight T2 but uses advanced, smooth welded, Kinesium tubing to make it one of the lightest and most responsive winter trainers available. Using the proven race inspired geometry of the Racelight T2, the Racelight Tk2 takes the winter training frame to a new level, and by using advanced Kinesium alloy, we have bought the weight of this frame down to 1.46kg for the 54cm size. Both the ‘T2’ and ‘Tk2’ use longer headtubes for a more upright riding position and have rack mounts and ample clearance for full size ‘gaurds and larger winter tyres [long reach, 47/57mm brakes required]. The top tube is ‘power bulged’ at the headtube for maximum stiffness and the oversize, thin-wall down tube is aero section at the top and ovalised where it meets the BB for maximum weld area and response. The ‘hourglass’ seatstays give maximum comfort for long training rides and the oversize chainstays and large downtube area at the BB keep power loss to a minimum. 48, 51, 54, 57, 60, 63cm [c/t] [Seatpost – 27.2, Mech. - 31.8, H.set – Integrated, 11/8”, 36/45].
