It is no longer a legal requirement, to wear face masks in shops. However, it would be appreciated, if those with "Flu like" symptoms postpone their visits. Despite the relaxing of restrictions, only one customer (Or party), at a time, is allowed to enter the shop. Please wait by the gate, if there is someone in the shop when you arrive (Or join queue if already formed).

Gear Chart & Calculations

The calculations below are approximate for 700c & 27 Inch wheels.

To calculate the exact gearing, divide the number of chainring teeth by the number of sprocket teeth and multiply the answer by the actual rolling diameter of the tyred wheel. (Divide actual rolling circumference by 3.142 to calculate rolling diameter)
