Grib Snail Cams 17mm

17mm - Wheel eccentrics to tension the chain, a new design that guarantees that each click tightens the chain exactly 1.6mm. This does not happen with the rest of the market excenticas since each click tenses different measures.
The P25-17 has a 25mm tension stroke and is for 17mm diameter shafts. Made of duralumin to guarantee great hardness and low weight. 
Anodised finish that guarantees durability, prevents oxidation of the aluminium, facilitates cleaning and gives a better appearance.
Easy lever tensioning, both for tensioning and loosening. The tension lever matches a 15mm spanner so you do not need any special tool or to hit it with a hammer in case it goes hard.
