Used for 1 week or less
bought item to enable a more upright riding position. on a touring bike as the one i wanted was a 3 day delivery from a company online, and i needed it that weekend .Installed as per instructions ( and i have fitted other makes of stem raiser on cycles before,) Firstly it advises knocking down the star nut to the lower area of the stem,? as a result when you fit the stem raiser you are unable to tighten the stem itself to the steering column . The clamps that they supply to hold it down are seriously inadequate and as soon as you try to ride and brake the whole steering column starts to come loose and chatter loosening the clamps further, until within 500 metres of riding the both the upper and lower sets of bearing on the column had come loose. Returned to store for a refund ,the person on the desk asked someone from the cycle maintenance dept to have a look, he firstly said that he hadn't fitted one like this before but couldn't see how it would work without a bolt going into the steerer stem. as you could not get it tight enough,i said this was the problem i had come up with , but now I was left with a steerer on the bike with a star nut knocked down into the steerer columns unable to fit any type of handlebar clamp.took nearly an hour to get the star nut knocked out fully to refit the original handlebar clamp.Waited for one off line, took 15 mins to fit worked perfectly first time.This is the first bad review had to give for decathlon bike parts, they are usually good quality but not this.
colour
dangerous ,appears to tighten but works loose.
