Zámeček ventilu (1 kus=2 poloviny)

Genuine Mini Spares product as everything else on the market was poor fitting and unstable.For Performance see 88G459EVO made in the USA by a Specialised Racing product company.All the earlier heads used the 2A11 cotters, noted by the wide slot in the valve. Later production and most aftermarket valves, use this 88G459 collet/keeper with a single narrow groove Pre APlus. Valve stems with 3 grooves as used on most A-Plus heads,use CAM6975 cotters. Order the correct cotters to go with the valves you will be using. When ordering these you get two halves to equal one cotter for one valve.
