    Chain “bunching” when back pedalling

    As the title says, but only when in the small chainring. Could it be due to the chain being stretched ? I am going to renew the chain and cassette anyway as they are getting to that stage. Before anyone says you pedal forward anyway, you often have to back pedal when adjusting pedal position...

    Is it time to change those chain rings? I haven't worn out a chain ring yet. I've upgraded mine before it's gotten 3 months old. Well not my current road bike. I'll consider it when my cassette is worn. Been wanting to complete the...

    Chain ring - suitable replacement

    At present I'm running an Ultegra 6700 compact chainset. I have just replaced the chain and cassette due to wear. First time I stand on the pedal to move off the chain rides up the teeth on the outer chain ring slipping and dumping me on the ground. It would appear that the chain ring is also...

    Chain Wrapping Up On Itself When Changing To The Smallest Chainring: Any Ideas?

    This has never happened to me before, but on the way home on Monday night, my drivetrain seized solid as I changed down to the smallest chainring on the way up a very steep incline (I changed down whilst I had good momentum so I wasn't loading the drivetrain). I walked the bike the rest of the...

    WD40 for the chain

    Hi, just wondered if it’s ok to use wd40 for the chain. Not long term use but at the moment with the poor weather I keep hosing the bike off after each ride so then spray the chain with wd40 or similar to drive out the water and stop it rusting between uses. Would this offer enough protection...

    Replacing cassette, will I need to use a shorter chain?

    Hi, I will be replacing the 8 speed cassette on my bike soon (the bike is only used for going to work and back), the current cassette is a Shimano HG200 t12-32. If I replace it with a Sram PG850 t11-30 would the current chain length be ok or would I need to take an extra link out? The chain...

    chain broken, could it be the result of cleaning method?

    Last night my chain broke on the way home, resulting in a lengthy walk home, thankfully punctuated with a few downhill coasts to break the mundane progress :biggrin: I didn't take a picture of my chain after the event as it was dark, and I was in a hurry to get home, it went in the nearest bin...

    Should have gone to Specsavers - Chain advice

    I fitted a new chain recently and stupidly routed it on the outer side of the cage plate housing the jockey wheels, rather than on the inside. I've been running it that way for 500km wondering why it sounded so rough. Yes, I should have gone to Specsavers. Doh! 🙃 🤷‍♂️ Anyway, I've now refitted...

    Bike chain maintenance

    Hi This is my current approach and wanted to check I was on the right track. Will use a degreaser, to get off all the rubbish on the chain. Then will hose down to make sure all degreaser off the bike. Then will spray on GT55 and apply wet lube. I will back cycle the bike and use a cloth...

    New chain comes off triple chainrings

    I have two tourers with triple chainrings where over the years I've noticed new chains sometimes come off the lower chain ring, but not after it is worn in. Neither bike normally has any problems with dropped chains as L screw and cable tension are correct. The dropped chain issue has only...

    Wahoo Kickr Core - Chain Rub

    I have just attempted to setup my Cannondale CX on my Wahoo Kickr Core for the first time and initially tried to get it to work on a 130mm adapter. The frame would not sit flush so turned the provided adapter to 135mm and sat first time round. Next I tried to pedal and on the front derailleur...

    Shaft driven (no chain) single gear bike (Walens Trident) - Leeds

    Bit of a strange one, hence thinking people on here may be interested. I have for sale a Walens Trident, single gear shaft driven bike. The shaft is shielded within the chain (or shaft) stay, and access is through a panel toward the rear of the stay. I've given it a quick once over and...

    Chain splitter

    I've just bought a chain splitter like the one in the picture off ebay. It came with no instructions. I can push the chain's rivets out and back in again by just turning the handle. What is the black screw on the other end of the body for?

    Adventures in OCD: Today's Chain Waxing

    A divisive and arguably thoroughly boring subject, but I'm sold for the most part. Today having covered around 380 miles since the last treatment, the 11sp KMC chain on the CdF was a little overdue another dunk in the pan. I usually check the chain for elongation before every 2-3 waxings; my...

    I have an old MTB with 6 speed Shimano Uniglide cassette and 3 x Biopace chainrings making 18 gears in total. Is the Shimano Altus HG40 6-7-8 speed chain the correct one? The pin lengths are the same as my KMC chain at 7.3mm. THanks for any advice...

    Chain not moving to big ring

    Hi, so basically as I was cycling I was not able to shift my chain from the small ring to the big ring. So I got home and undid the bolt and pulled the gear cable for tension and now the gear shifter has gone very soft and the front derailleur does not even move when I shift gear unless I...
