Retention system
Retention system
Since modern helmet designs were first introduced, the way they stay in place on the rider’s head has subtly changed.
Originally, it was down to the straps that travel down in front of and behind the ears and meet below the chin to keep the helmet on. Today on most helmets it’s standard to get an additional retention system which can be adjusted to fine-tune the fit.
There are a number of variations when it comes to the design of retention systems and how they are adjusted, but essentially they all work by pulling together what is essentially an adjustable webbing system across the back of the inside of the helmet. To run through a couple of systems, Belgian brand Lazer’s RollSys device uses a thumb wheel on the top of the helmet, while Italian firm Kask, like most manufacturers, have a ratchet dial on the rear of the helmet. Either way, what you should look for in a retention system is something which can be easily adjusted with one hand while on the move. More complex systems (often on more expensive helmets) will also some kind of height adjustment, again allowing you to get the perfect fit for your head shape. Finally, It’s worth seeing whether you can comfortable fit a cotton cap under the helmet and retention system.
For most riders, what retention system works for your is simply down to personal choice, but for those with long hair it can be a deal breaker as some won’t work if you have a ponytail. Specialized even makes a women’s specific helmet, the Andorra, with a ponytail friendly retention system. Once again, it’s a case of try before you buy if you have long hair. Even if you don’t, it’s advisable to visit a store to get first-hand experience about how the system on the helmet you choose works and how it should feel when you have the helmet on.
