    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?

    Goodbye indexed gears?

    Hi, This is a similar post to @Biker2772's about slipping gears. I suppose all cases are different, so I'm posting my own thread and I'll paste below some detailed images. The gears Ultegra with this code embossed: "RD-6500 VIA". The bike, a Principia Rex, is 20 years old and I bought it...

    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)...

    Do both of the rear derailleur have the same mounting system?

    Rear derailleur barrel adjuster insert thread stripped.

    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...

    Shimano Tiagra 10 speed rear derailleur - Spring and Pin

    Hello I needed to remove and replace the cage / plate on my Tiagra rear mech as it was damaged and bent. I had a replacement at hand. I removed the securing pin and the spring that is loaded inside obviously came out. I've tried several times to reload the spring but I am not able to get the...

    Ultegra 6800 rear derailleur, B screw fallen out

    Hi all, I wanted to double check for opinions on how much of a problem it is if the B screw on my Ultegra 6800 rear derailleur has fallen out? I had two incidences of rear derailleur issues in past six months, the first time the hanger snapped whilst shifting, which I then replaced and carried...

    Rear Derailleur. Standard Mount Or Direct Mount?

    Just about to clean the drivetrain and I've noticed a bit of damage on my well worn rear mech. Looking to buy a replacement and I have come across "Standard Mount" or "Direct Mount" (often both?) being used in the online descriptions. So here's a piccy of what I've got. Answers on a postcard...

    Help with rear derailleur

    Got a carrier bag stuck in my rear derailleur on my way home yesterday, it’s totally knocked my shifting out, not sure how?

    Rear derailleur only shifting to larger cogs

    Bit bemused, apart from the smaller cogs I cannot get the hybrids rear derailleur, a Shimano Tourney 6/7 speed, to drop onto a smaller cog, changes up to each larger cog without a problem. Is it new derailleur time?

    Rear derailleur configuration

    This is just for thought. Please don't respond with vitriol. We all have personal preferences, no one school of thought is correct. The very first derailleurs manufactured in the 1940s and 1950s had a spring pulling the slider towards the largest sprocket (just like today in low-normal /...

    Rear derailleur problem or not?

    I don't know if this is a problem or not so thought I'd better ask here. I have a Giant road bike and the rear derailleur is a Shimano Claris. I've just tried adjusting my gears after they started to jump a gear when I shifted to the largest sprocket on the rear cassette. It seems to be working...

    Rear Derailleur. Will I be Shunned?

    Not entirely serious here, but is there any reason I shouldn't? I mean, a mountain bike mech on a road bike!! Burn him! I have a couple of other choices. A very nice Mavic job. Trouble is, it will be used in all weathers and that particular mech operates on a weird circlip spring loaded...

    new rear derailleur for old school 80s road bike.

    So 80s era road bike. I recently changed both 8 speed rear cassette (now 11-32) and added a smaller front chainring (now 38-52). My derailleur is Shimano 105 from that era, I have down tube friction shifters. The derailleur is a short cage (SS in Shimano terms) and I want to change to a medium...

    Rear derailleur cage size

    On my rear derailleur I have a long cage. Should it be a short cage on a road bike? Just been comparing it to friends bikes.

    Le Cyclo Rear Derailleur Shifter

    I've just acquired a Sun cycle with the above deraillier. I've tracked down a NOS tension spring, and the rest of the mechanism looks like it will clean up well. The cable is a continuous cable which is in tact but just thinking out loud where and how do you replace these? Picture for reference.

    When replacing a chain at what angle should the rear derailleur be?

    Photo 1 is in biggest rear cog and front on biggest ring Photo 2 is in smallest rear cog and front on the biggest ring. I feel that in photo 1 the angle of the rear derailleur is a bit too much??

    Poor shifting - replace rear derailleur?

    Shifting is poor and when in any gear it isn't smooth. I've tried to adjust tension etc but it makes little difference. There is some play where the mec attaches to the hanger but tightening the relevant bolt makes no difference. Does anyone know why this is the case? I have fallen on that side...
