Which gear dropout hanger for b'Twin RR 8.1?

esuhl

My rear gear dropout hanger is bent, causing shifting problems, so I need to replace it.

It seems like there are hundreds of different shapes and sizes, and I haven't found any websites that mention the bike model I have -- it's a Decathlon b'Twin RockRider 8.1 (2010 edition).

Would anyone know how I can identify what type of hanger I need and source a replacement?

It could be just a case of looking for one that looks the same and then e mail the store.
Try "Chain reaction cycles" they seem to be on the ball with odd questions and very helpful.
Even ask decathlon
You can straighten the hanger so that it works better until you get one.

I doubt you will find anywhere that will drill down to model, too many possibilities of change mid production run. You need to get it off and compare to the diagrams.

To choose the right hanger, please compare your actual hanger to the picture. If there is any doubt, send us a good quality picture of the actual hanger or/and frame (around the hanger place) at

I would ask Decathlon first as they supplied the bike and are the only retailer.

Cheers everyone! I've emailed Decathlon, and I'll take the hanger off tomorrow so I can have a proper look and see if I can match it to one of the photos. Those links look really helpful, so I should be able figure it out. :-)

Aha! It looks like it's a D187 hanger. I've just ordered one! Thanks again!

I've had this issue with my new bike, luckily I don't need a new hanger but want one should the worst happen. Tried a few places I already knew and even emailed Wheels manufacturing in the US who could supply a hanger number but did provide a link to soshanger who have the right one for me but payday isn't till later this week.
