chainring

Normally, chainrings are mounted with a number of dedicated allen key bolt head+sleeved nut, sunk. The pedaling force is transmitted from crank to spider, from spider to chainring, the latter along full contact of cilindric outer side of bolt/nut, with the alumium around the hole in the...

LBS supplied this to replace one they ordered by mistake , which i took back with the intention of installing myself but i know it would look odd as the arms dont marry up neatly to the old chainset 11 speed Plateau T.A. X110 110 BCD outer 50 tooth still in original packaging unopened , brand...

I need and am struggling to find at pre COVID tax prices, either a chainset 50/34 ideally 175mm can be non series like rs500 or 510, or a 5800/6800 50t chainring. Anybody got anything please?

https://www.parktool.com/product/chainring-nut-wrench-cnw-2 This seems too good to be true: a PARK TOOL for under a fiver, about half the price of the equivalent tools from "lesser" companies. What's the catch? Are they the best tool for the job?

I have a Giant Defy advanced 2 running shimano 105 gearing 10 speed. Chainrings are RS 500 50/34, 5 hole with a 110 mm BCD. they have lasted pretty well but are now worn and due for replacement. Only problem is that Shimano no longer make the RS500 rings. I’ve looked online and the Shimano 105...

As per the title I have a Shimano 5800 52T chainring which has an integrated threaded bolt hole in the chainring itself rather than the older method of chainring bolt pairs with male/female, this model just has male bolt that screws into the ring, the problem being the screw body is pretty weak...

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...

Just done the mod on my S3L as I was finding 3rd a little tall. Im so impressed with the modular engineering on this bike. I think this will be the icing on the cake of what I believe is the best bike I have ever owned.

I have a Cannondale Treadwell 2 hybrid bike. It has just 9 gears with a single front chainwheel and a 11/42 rear cassette. It has Micro Shift Advent gearing. Despite many efforts to fine tune by both myself and my LBS I am now utterly fed up of it slipping all the time. I want to upgrade but am...

Hello there! How long are Shimano compatible chainring bolts on fixies / Singlespeed bikes? Ideally I need the length of both halves of the bolts (male and female) separately and if possible how long the parts are when bolted together. Annoyingly I forgot to measure the chaninring bolts before...

I broke a chainring bolt. The alloy threaded collar is fine, it is just the bolt that broke off (which I managed to remove from the collar). The chainset is a Deore XT M770 2009 triple. The bolt is for the outer / middle chainrings not the inner granny ring. They are T25 head. They are proving...

Finding a replacement triple for my junior MTB bike build is proving... challenging. Especially when on a limited budget. There's not much out there for square taper and cranks of 165mm or less that isn't going to cost me an arm and a leg. Spa do a very nice touring triple, having said that, but...

Over the course of the lockdown my wife has been cycling most days, having previously been a very infrequent cyclist. She has been using a Pinnacle hybrid (Sora groupset) and is quite happy with that. However she is now keen on acquiring a drop bar bike for occasional days out when it's dry...

I have some seriously worn chainring bolts - no chance of undoing them with an allen key (of the right size). I don't want to buy a special tool to do the job. I have watched a couple of YouTube videos which didn't help. I have thought about hammering a screwdriver into the rounded off hex...

This chainring came with a GRX crankset but was removed before use. Cheapest I can find these is £46.99 so will do for £40 RMSD. Cheers, Pete

Had quite a shock this morning when i looked at the price of outer chainring (road bike) prices for the newer type ie Shimano 7900 prices? Seems to me that a bit of plastic on the side of a chainring puts the price up by about %300? Does any one else think this is a rip off ? Or know any way of...

Hi everyone! I am new to cycling. I bought a Mountain Bike last month and use it primarily for city commuting, exercise and going to the park occasionally. I have a 1 x 10, 32T chainring with 11/42T cassette. The gearing is 11-13-15-17-19-21-24-28-32-38-42. As my legs have gotten stronger I...

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...

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...

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)

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

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?

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.

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...

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...

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...

Does anyone have a 4 bolt 9 speed chainring lying around? It’s an old (2009 or thereabouts) drive train with the offending chainring looking like this; https://www.wiggle.co.uk/race-face-9-speed-chainring/

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...
