    I've got a faulty Di2 Shimano RD-6870 rear derailleur, medium cage. the item is faulty. The derailleur causes the di2 battery to go flat in a couple of days. My local bike shop did a diagnostic test, and found that this derailleur was the cause of my flat battery issues. The derailleur...

    Why you need to own a derailleur hanger tool

    When I go into a bike shop and look at the wall of tools—usually Park tools—I am stricken with a serious bout of envy. My own shop tools all fit into one small carry box, though it has many of the necessaries like a torque wrench, chain tools, spoke wrench, etc. I've long considered the...

    Replacement dérailleur

    I need to replace my Shimano RD2300 dérailleur as it's making rattling noises and The pantograph pins also seem to be worn, and it's not reliable changing down. I was wondering if I can replace it with a Shimano Claris mech.

    Specialized Allez derailleur problem

    My Allez has been skipping gear and making a rattling sound from the cage on the derailleur. I have fitted a new chain and cassette, but the gears still skip. On closer examination, I think that (a) the jockey wheel bearing are a bit worn (They wobble) and (b) the pins that hold the body...

    Sachs Huret derailleur

    I'm restoring a Raleigh Winner and I can't workout how to attach the derailleur to the frame. It's the odd shaped nut and bolt that's got me at a loss. Any help would be appreciated.

    Rear derailleur

    Hi, been playing around with my rear wheel then noticed my gearing was a bit off. Does my derailleur look bent? If so which way do I need to adjust it?

    Torque of derailleur hanger screws

    Quick question, I was checking for the source of a creak, and noticed that the screws that hold the derailleur hanger onto the frame felt very loose. The frame is aluminium, and the screws look like steel, so don't want to risk stripping the threads on the frame. Anyone know what’s the...

    Rear derailleur adjuster spring....(gears jumping on smaller cogs)

    Can I assume that the spring that is housed in the rear derailleur barrel adjuster actually helps with the cable tension. I lost the damn thing whilst replacing the cable! Basically, my smaller cogs are jumping, despite adjustments (two evenings after two rides) And, what does the (B-Tension)...

    Now sorted - Brompton derailleur trigger (pre-2017 type, with bell)

    Just as a spare so I don't have to change everything (or have mismatched brake levers, the horror) if mine wears out.

    Which derailleur for 7 speed?

    Hi all This is on an 87 Raleigh Randonneur. I've just changed the 6speed block to 7 (the dizzy heights of 1989 now) it went in fine with the addition of a washer on the drive side to space it a little. I have put SIS dt shifters on which came from a 7sp Galaxy recently so I know they work. Thing...

    Rear derailleur cable snapped today out on a ride. 8 speed sora (sora is now 9 speed but bike is from 2013 so was sora at time). I digress! On taking old cable off to replace new cable I couldn't get the barrel adjuster back in. On inspection the thread on the actual derailleur seems to be...

    Rear Derailleur Movement Blocked by Frame

    I've just been given an old bike which i thought I could get working. The chain was actually snapped, so I managed to get it fitted again and borrowed a friend's chain tool to close it. I repaired a puncture on the front and was all set to give it a try. The rear gears don't change .. on...

    The end of the front derailleur?

    A new company in Belgium has come up with a very clever replacement hub gear that does away with the front derailleur. It's controlled by Bluetooth and can even shift under full load: View: https://youtu.be/UFMhUYoqFyc Could this be a game changer?

    Correct derailleur?

    I have a 2014 105 10 speed groupset, and have just upgraded my cassette from an 11-30 to 11-32. I got a new chain at the same time, however I didn't realise I had to also get a larger derailleur. I'm not up to speed on these things, so how can I tell which dersilleur is correct - as I also...

    Rear Derailleur - Lower Jockey Wheel Screw Loose

    I have a rather high mileage 9 speed Shimano Ultegra Rear Derailleur and the Lower Jockey Wheel retaining screw will not tighten or bite. As a result, the jockey wheel was only held by the one (outer) side and was not locked in to the inner side. It had worked loose. If I remove the lower...
