I want to tell you my experience with this product ... Here we go:
So I created this clutch bought last week at random, because it looks in the photo as well as my old broken clutch and a further order reason was that they cost less than 8. So do not shilly-long and ordered the next day it was there! Now my new bike was there and the clutch ratzfatz grown for cultivation have to be genuine, no Head of the Class! Soon to clarify, I have a child bicycle trailer Tiggo as offered on Amazon for under 130. My new bike has a Shimano Nexus circuit since such coupling fits perfectly ran! But be careful before I had a standard derailleur plus disc brakes, as has my clutch did not fit, from experience I can you only advise of such or similar coupling buy if you have a chain or gear hub on your bike, as it gets only problem and the shit does not fit back and forth because the axis in most cases much too short and the mother no longer really gets up "risk of falling"!
small tip from an experienced Fahrradschrauberin you should the cultivation between the bicycle frame and a rubber coupling or hard plastic slide washer on the axle, which prevented many nasty scratches on the frame ...
Now I hope I could help you!
This article has clearly assuming my buy recommendation on which one fits circuit so you have!
I'm still the way a pick me next month for the bike of my friend, I think that explains everything ...
What should you get her before the panel-mounting is usually a 14er Ring or mouse key very few need for your bike a key 15 and a washer above all you need to do not grow! Crop season and degree adjustment to the car max. 3 min. (Time generously interpreted)
Unfortunately I can not give you more information about it, for which the trailer coupling is still, except for Trixie and Tiggo bicycle trailer!
