Hsthe Sea Mountain Bike Rear Derailleur 7/8/9 Speed for MTB Bikes Direct Mount type

For the price it's fine & I'd say a lot better than the equivalently priced Tourney derailleur. I've fitted quite a few of these on basic fixer-upper bikes to resell & so far haven't had any issues. Others have mentioned that the jockey wheels are not replaceable/removable, however in my experience once jockey wheels are worn out on other derailleurs, the pivot bushings are shot so time to replace the lot anyway. Also these MicroNEW derailleurs (what on earth is 'Hsthe Sea'?) are available a lot cheaper from a certain 'express' marketplace

I own a bike shop I bough 15 bikes without derailleurs I bought one and it didn’t fit in a single one

Let's face it - if you're buying a derailleur and see it is this cheap, then expect the same results.This product is of poor quality, and the cogs were fixed. The build materials are not great, and spring back equally so.That said, it served a purpose on a temporary basis. If you're looking for something with a view to not replacing it, then other branded products is worth forking out that bit extra.It isn't something I'd buy again, as I soon needed to change it after a few rides.

Great value does exactly what it says on the tin easy to install and set up.
