    £14 Fixie Chainring Bodge

    I had a old Apollo MTB that cost me a tenner. It had a noisy Freewheel so doing a single speed conversion at a cost of £4 for a BMX Freewheel. I am using the middle ring on the OEM Chainset which I know is not supposed to come apart, I know the 2 redundant rings won’t do any harm left there and...

    Absolute black subcompact oval chainring / tiagra crank issues

    So it says on their website that the 46/30 absolute black chainrings can be fitted to tiagra 4700 cranks.... With a little adjustment.... After I brutalized the cranks for a while with a file I just about got them together with the rings. But for the love of all things Holy I cannot get them to...

    Wobbly chainring

    The top of my chainring moves laterally by up to 5mm during a single rotation. Is this usual on a 1990 Raleigh Chiltern? If I tighten up the bottom bracket to reduce the movement then it binds in some places. (I'm currently waiting for a crank puller to remove it and inspect it properly)

    When Should I Need to Change Chainring?

    Hi Some advice needed on chain ring wear. Have done approx 12k miles on an FSA chainset, pretty much all of it on large ring (it's flat round here and I'm lightweight) I've attached a photo. Would you consider I need to change the large ring or is it still OK do you reckon ? thanks in advance

    Absolute Black chainring Shimano/SRAM compatibility

    I have in my ‘eBay/car boot bargains’ box cycling stuff I have acquired at a bargain price. Whilst looking through I found a almost new 5x 110 bcd Absolute Black oval chainring. It’s marked specifically for some SRAM cranks. Should I have a go trying to get it to fit my Shimano 105 set up?

    Bigger Chainring on a 1 x Gravel Bike

    Hi Guys I have owned a Ribble Gravel Bike for a little while now. It is kitted out with a SRAM Rival 1 x 11 groupset This is 42t up front, with a 42-11 cassette. I have found that i have very quickly run out of gears and spend a lot of time sitting on the 11t cog. I would like to replace the...

    Anybody got a spare 30T chainring suitable for a Shimano Claris 8 speed? I have a triple chainring but the smallest ring is missing. I believe the smallest it will take is a 30T. I'm willing to pay of course. It doesn't have to be a Shimano as long as it will work.

    New chainring time..

    I think it's time to pop a new chainring on this but I am having trouble making sure I obtain the correct one. My chain's slipping again despite being within 0.5 and 0.75 on the wear detector, and on a new cassette too. A new chain is on order. It's an 8-speed Claris transmission with an FSA...

    chainring bolts

    Question: The Stronglight Track 2000 chainset has mounting bolts whose female (the part at the side of the frame, the "nut") part is not entirely cilindric, first a kind of ring, slightly larger diameter with grip ridges that fret themselves in the alu of the spider of the crankset, then a...

    Single chainring on Campagnolo Record ultratorque carbon 5-arm cranks?

    Hi folks, thanks to Campy's usual "heck you, we're Campy!" attitude the Carbon 5-arms use a special set of bolts, the threads on the four normal arm bolts are M6x0.75 and the hidden arm bolt thread is M8x0.75 ... does anyone one make a set of bolts to go single-ring on these or am I going to...

    Removing a stuck chainring bolt

    Not just any stuck chainring bolt - one stuck by my own stupidity. Will try to explain as best as I can. I was doing some tinkering with an unused 8 speed triple Shimano chainset, seeing if I could get some brand new chainrings from another Shimano 9 speed series to fit it. In screwing the...

    Shimano 105 5600/5700/5800/R7000 chainring compatibility

    Hi, I need to change one or probably both of my chainrings on my 50/34 5600. Surprisingly, there are not that many available replacement parts available. Could I use a (11-speed) 5700 chainring or even 5800/R7000 one or is that a silly idea? Thank you

    Chainring bolts for Ultegra R8000

    Whilst doing some maintenance today managed to strip the head off of one of the chainring bolts on my Ultegra R8000 chainset, does anyone know of a decent supplier for new parts? As a temporary measure I've cannabilsed a bolt from another 6800 groupset which seems to fit. A general search on the...

    Is my middle chainring ok ?

    Hi I've just been cleaning my bike and noticed my middle chain ring is a lot more worn than the other 2 do you think it needs changing or will it be ok for a while. Also I seem to live in the middle one and was thinking of going 2x instead of 3x with something like 36-28 or 38- 28 I'm currently...

    Another Chainring question.

    I'm still undecided about the 44T chainring. Loving the fact it makes the hill near home easier, but for the sake of one 6 minute climb, it's compromising other aspects of the ride. As Brompton only do a 44T, 50T and 54T, is there any reason why I couldn't switch to any other 130BCD 3/32...

    Stuck 6800 chainring shifter after swapping cables

    Hi all, a common question about stuck shifters. I remembered freeing up my old 6700 before with GT85 and an air duster but tried the same on my current 6800 shifter and didn't work. Also swapped out the inner gear cable but problem seems to be that the cable ends are not moving in the shifter...

    Chain ring PIN lost from large ring-what is it`s function?

    I have read two different opinions regarding the purpose/function of the Pin . One was that it stops the chain getting jammed if it came off the ring. Another was that it helps the chain move across to the next chain ring when changing.

    Does this chain ring look worn?

    I have been looking at a used bike online that I am interested in. It is described as one year old. I don`t know much about bikes but some of the teeth on the chain ring look a bit different to the rest of them.

    Chainring bolts

    Hi all, Somehow managed to lose the single bolt that attaches round the back of the crank rather than one of the ones for the holes on the spider. Without wishing to purchase an entire new set just for one bolt (especially as I have a spare set of the other four) does anyone know where I can...

    Missing chainring bolts

    This morning I noticed that 4 of my 5 chainring bolts were missing. The one near the crank was in place. Never had them come loose before. Is this a mechanical or a thieving toerag?

    Chainring Options...........or not as the case may be...........

    I'm currently running a Shimano 6700 53/39 chainset on the CAAD, just like this one; Looking at chainrings I think I'm stuck with the standard ones due to the shape of the spider, is this the case or has anyone found any alternatives? FWIW I fancy oval rings but think I'll have to swap the...
