Image: 114 - Cracking Nuts, Sprocket!

The Biketek sprocket nuts have just arrived in our online shop. Apart from being resplendent in anodised red, black or gold finish, these save a good deal of weight compared to normal steel sprocket nuts. This weight is unsprung where reductions really count, and every bit of rotating mass that takes less energy to accelerate makes a contribution, however small to the power available to drive your bike forward.

These will suit most modern bikes, being available in 10mm and 12mm thread. There is no loss of strength either as the threads are formed in stainless steel inserts, so you can be sure that your sprockets are securely attached, and can be changed over and over again without wearing the threads. Now, we reckon that has to be £15.99 for a pack of six, money well spent.
