chainring

I know they're not to everyone's tastes so was wondering if anyone had one stuck in the parts bin/box. They seem a bit hard to come by / excessively expensive at the moment. It's for a shimano 311 so I'll be looking to pay a tenner or so. This is the badger I could do with replacing

Seriously nerdy question here. Do folk ever remove their chain rings to clear all the grot out that sits in all those chainring/crank corners? Or is it just pointless - the grot/road debris will just get there again in no time? And maybe is in any case no great problem/won't degrade anything...

I need to replace my worn front Chainring, Shimano 105. The existing one is FC-5800 50 tooth which I cannot seem to find anywhere. Do you know if the FC-R7000 is a compatible replacement? Thanks.

The teeth on my outer chainring have become pointy, the chain often slips off onto the small ring when under load. Can the outer ring be changed? It a 10 speed SLX M675

I dismantled my triple chainring to have a decent look at wear on the middle ring (hence my recent search for a compatible replacement). In doing so, I noticed that a couple of the bolts weren't particularly tight. When I reassembled everything, I nipped up the bolts at tightly as I could with...

Next time I need to change my chainring, I might look at something a little smaller than the 50T I currently have. Tried the 44T in the past and it wasn't right. So looking at a 46 or 48 if I can find the right thing. Why? After almost a year and a half of not using my Brompton, I was in at...

My fault for letting the chain wear to 1% (and of course doing most of my pedalling on the middle ring). :sad: Original was a Suntour CRG730-36T, but they're pretty well unobtainable nowadays.

Having discovered that two out of three of the Scott's chainrings were attempting to go AWOL, I'm awaiting a proper chainring bolt tool from SJS. Is that it, apart from more regularly checking, or is a dab of some threadlock a good move? TIA.

Hi all, I have my first sportive in 5 September (Tour o the Borders) and so I took my bike in to Decathlon for its free safety check seeing as I have had my bike for about a year now. Unfortunately they told me that my chain/cassette/big chainring was all worn out. :wacko: I had actually only...

Hello I’m trying to find information on a crank that was removed from a Dawes Made in England stamped UtilityAny idea?

After the Great Evanscycles Fiasco concluded at the end of last week. I was all set to go on my first ride on Saturday, I get the bike outside and start pedalling, only to realise I'm going nowhere as the chain has decided to remove itself from the chainring. "Easy enough to fix", says I before...

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...
