derailler hitting spokes on uphill
good afternoon,
Have recently been bitten by the cycling bug again, love it!
I have an issue with flexing I think if I get out of the saddle on a reasonable climb i can hear the derailler snagging the spokes is there an adjustment I can make?
Am wondering if I need to pull the derailler out a little bit and or check the rear wheel isnt having a bit of movement with my poor form?
Thanks for any advice

Most probably the low gear stop on the rear derailleur needs screwing in a smidge to stop the derailleur from moving towads the rear wheel so much. Won't need much, just a wee turn, then make sure you can still change into bottom gear.WyndyMilla Massive Attack | Rourke 953 | Condor Italia 531 Pro | Boardman CX Pro | DT Swiss RR440 Tubeless Wheels

It's your limit screw, fix it today. Or you'll be starting a new thread soon "my wheel and derailleur exploded".0

Yes, definately fix it before your next ride!WyndyMilla Massive Attack | Rourke 953 | Condor Italia 531 Pro | Boardman CX Pro | DT Swiss RR440 Tubeless Wheels

It could be the limit screws, but if the gears were well-tuned and working fine recently, I'd say it's more likely to be a bent derailleur hanger. See it all the time, takes a knock when the bike is being transported or locked up somewhere and suddenly the rear derailleur cage is clipping the spokes in the low gears.
You don't say what bike it is, but if you're not confident fixing it yourself, take it to a shop.0 -
What a helpful bunch, thank you
Ive never had a problem with the gears lining up,
have had the bike about 6 weeks a moda and tbh on an early ride it did it and my mate said here i know what that is and pulled the derailler a bit and no bother until 800 miles or so later. Ive just pulled it slightly again, and will get it onto a workstand to check its all lined up.
thanks again0 -
Look from behind when in the lowest gear (get off the bike first!); the derailleur pulleys should be vertically aligned beneath the largest sprocket. If there's a suggestion of a lean inwards so it's nearer the spokes, it's likely a bent hanger and needs replacing before you rip off the rear mech.
I've bent the hangers on both my bikes, both after a tumble onto the drive side. That tinkling noise as the mech hits the spokes is quite terrifying. One hanger I managed to straighten using a vice and large adjustable spanner, the other I just replaced.0 -
I have the same issue. I just gave up trying to fix & stopped using the cog, I set the limiter so it won't shift onto the last cog.
Miss using the 23 cog though :evil:
Bending the hanger to try straighten it didn't help fix problem (I though It must of being caused by a bent hanger though I never dropped the bike etc?)
Ive bought a new 105 rear deralier I might on try sometime.0 -
guys,, fix it now before you ride again or else it can get very painfull and expensive as I know very well. Luckily it happened to me on my cheap commuter hack not my best bike. I left work one day as normal on my flat bar commuter which is well adjusted and maintained. no problem until I got to the one hill on my way room and flicked down to bottom gear, Crunch the rear wheel ate the mech locking everything solid and chucking me into the road, luckily just a few bruises and grazes, end result rear wheel, rear mech and hanger totally knackered. As I said the bike was well looked after and adjusted so I can only guess that it had been bashed or knocked over in the bike rack at work without my knowledge. fix it before it hurts you0

Also, check that the gear mech hanger is securely attached to the frame - I have seen the screws work loose on a frame with pretty catastrophic consequencesMake mine an Italian, with Campagnolo on the side..0

I'm not saying don't check it out properly, but there are setups where a very light spoke/mech interference just happens. I had it with some DT Swiss hubbed Reynolds running Campag, for example. Straight hanger, properly adjusted etc.0

Is your wheel sat straight in the dropouts?

A weak wheel will do this when climbing out of the saddle if the gap between mech and spokes is small. Undo the mech cable and move the mech over by hand moving the chain at the same time until you reach the limit screw. If that happens before you reach the spokes and the sprockets line up with the biggest cog then its not the limit screw. Some wheels tinkle when climbing caused by the spokes rubbing where they cross, Campag Neutrons do this. Apply a bit of lube at the spoke crosses.Pegoretti
