The derailleur exploded

After months riding and maintaining it, one day I was riding small jumps, I landed therefore the derailleur suddenly exploded, the cogs were fine but the whole derailleur just broke into 2, scratching my frame paint and it bent my 8 speed cassette too

Hi Roy

If you're looking to execute stunts on your bike, this is not the ideal derailleur. Nor bike, assuming you are running a bike with 8 speed.

I would suggest you try looking for a proper DJ or slopestyle bike.

Or upgrade your drivetrain system that has a clutch mechanism.

Shimano derailleurs that has a clutch mechanism usually require you to spend quite a bit of cash there to get product designed for it's intended use as usually you would need to swap the entire drivetrain system.

Otherwise, my suggestion is go Single Speed with a DJ frame.

Good but not up to the 9 gear mark

The shifter is sturdy and will shift easy till 7 gears, pushing it till 8, but could not go to 9, in my MTB. It needs more flexibility in the side swing to cover 9 gears. However, it is really good for its price tag.

Update after 3 mths use

the pulley cage dented badly one day while cycling uphill but fortunately Decathlon's exchange policy is excellent! Had it exchanged and installed by one of the bike techs! Shifts even better now and i have to say your refund/exchange policy is one of the best in SG and inspires confidence and trust in customers - keep up the good work!

Good for the Price

A little difficult to fit but luckily I have a besite who knows how to do it. Ok for an everyday cheaper derailleur.

works well, Bargain

used this on a 1996 Road bike to increase gear range ! Cheap cheerful and easy to set up

Good Replacment

I am a Professional Bike Mechanic and I needed a reasonable priced long cage rear mech which was Shimano compatible. I had not purchased one and called into Decathlon on my way past to get some cycle kit. I picked one of these units up for the repair I had to do on a Raleigh Ladies Mountain Bike..... The Mech fitted with no issues at all aside of setting up the low and high limit screws as this was being fitted to a 7 speed freewheel. The bike was fitted with the awful grip shifts and with this unit it works 100%... so a cheap and great replacement for O.E equipment
