The Qu-Ax TA (36 x 2 1/4) tyre has been around for many a year now and has proved itself as a fine road going tyre. Until now though it has always been a little on the heavy side sitting at about 2.5 kg. We have just received the new lightweight version of this tyre. The tyre tread has stayed the same but the weight has dropped to just over 1.6kg. So if your in the market for a new lightweight tyre for your 36 road Unicycle perhaps this is worth a consideration.
