Great product, does its job, highly recommended for EVERY geared cycle
Because last thing you want after a crash or fall is to walk your cycle back home and somehow take it for repair. Save hassle, save time and if going for long rides, save frustration and get this.
You may not realise its worth if you. buy it, but 100% will regret if you don't buy and for some unfortunate reason the RD gets impacted , which is always scary.
My only recommendation for Decathlon is to make it little bit longer and see if price can be reduced since this is a bit expensive for such a simple part :)
