chainring

Hi total bike noob here. Looking to buy a cannondale 2019 synapse Tiagra disc. Comes with a fsa megaexo bottom bracket and a fsa omega alloy 50.34 chainring. I would like to swap the chain ring for a Shimano Tiagra 4700 50.34 chainring. Just so it matches and keeps the group set the same...

Just changed the chain - how are my teeth looking? I'm not really sure what I'm looking for in terms of wear: https://ibb.co/jhmYP8r https://ibb.co/jHF5PGf Cheers

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...

My question is, can I just swap a 44t chainring for a 40t without having to change anything else except the chain length? I've currently got a 1x11 sram rival chain set.

I need to replace my outer chainring on my BTwin T500, its the Ounce groupset...I know its a 130BCD but can I buy any brand of that nature and install it? i.e are the boltholes in the same place whatever the brand?

Thanks to the contributors who helped me with a simple but very effective modification, particularly Fab Foodie, The Doctor, and Pale Rider. As I had no "bits-box chain-sets" I bought a new Stronglight 50/34 with 170mm cranks - same as the Brompton stock on my 2014 S6L with JIS taper BB...

I have been having some indexing problems with my Hard Rock for a while. I think I have finally sorted it. The middle chainring is no longer straight. Does anyone know if this is a design feature to aid shifting? How could I bend the inner but not the outer? Thanks in advance.

Hi, I have a 70s Galaxy and the front inner chainring is a Sakae 40T ( outer is 52) . I'd like to swop it to a 36 or 34, as the hills are starting to make me blow a bit, but I'm not sure what would fit! It has 5 inner bolt holes and they are 7cm apart, and the distance they are from the crank...

As per thread title - is the 105 5800 chainring in two parts? I've been tracking down a small clicking noise which occurred yesterday in my rarely used small/small combo. Not a real issue tbh but I thought that I would check hanger alignment (slightly off and corrected) and the rear mech'...

Any ideas on what these are on my 50 tooth chainring? One looks to be missing. Deep clean still in progress! Having a second look, the “missing” thing’s location hole looks a different profile to the others.

Having trouble finding a replacement chainring: Singlespeed 42 teeth 130mm BCD (five bolts) 3/32 chain Replacing now defunct model: Driveline TK-13 42T 3/32in There might be somewhere you know of that I have not looked yet; any help appreciated.

They're an odd slightly narrower size. Easy to get double ring bolts for (And I have several sets), but I am building a bike up to suit a single ring and I'd like to use a Campy carbon compact I have kicking around... I could make some as I do have the kit, but don't fancy several evenings in...

Hi folks, wondering if this is a solved problem somewhere, but haven't been able to trace an answer so far... Basically the issue is I have several Campy carbon compact cranks I want to use for various projects, the issue is I generally only need single front chainrings rather than doubles...

I have just stumbled upon this picture of a bike somebody lent me in South Africa. The big ring was something like a 62 if I recall. The FD wouldn't change down to the small ring, which was something like a 36 so the very hilly ride I did was absolutely exhausting as I ended up climbing...

Hi All, I have SS with a 46t chainring and a 16t Sprocket but, I think my knees are starting to crave an easier life. I changed from an 18t to a 16t over 12mths ago as I was starting to spin out once up to speed but, it is now the resistance when starting off that's begining to take its toll...

Hello fellow cycling friends. I've just cleaned up my old Kona Dew Delux that's been hanging around in my shed. Thought i'd lose the triple front chainring and go single. I never use the smaller rings. Makes sense. Looks tidier too. Ok, Too simple. Moved the large 48 tooth ring to where the...

Hi all, I'm changing my 2x9 setup on my Defy 3 to a 1 x 9 using a 44 front chainring. Does anyone know if I just remove both current chainrings and replace with a single 44t on the existing crank arms (in the outside position) if this will increase wear on the chain due to alignment or is it...

Excuse the few days of commuting crud on the drivetrain.What do you think regarding the chainring,would you replace or get another couple of thousand miles out of it? Im just about to treat it to new cassette and chain but will hold off if opinion is chainring needs replacing. The more I look at...

I have just changed the chainrings on my bike. There's a lug on the outer chainring that is interfering with the chain. Does anyone know what it's for. I have not noticed any of these before. Also, how are you supposed to get rid of it. None of my allen keys seem to fit.

Anyone tell me if the outer chainring is worn or is it ok ? Was going to buy it.Thanks.

I've just picked up a cross bike with the SRAM rival 1x groupset on and am loving the simplicity of it's operation. I'm now thinking about what I can do to get this on my road bike (currently 10-speed Shimano 105) with the minimum parts. I've been doing some gear calculations and I'm thinking...

Hi I've got a 52/36 chain set and given a previous 52/38 chainset I had with the same 11-28 cassette which coped with Flanders, hills in Scotland and Wynatts I think the 52/36 will be perfect for round here in the flatlands. (I still have the 52/38 on my commuter and it copes fine with the...

New chain started chain sucking on my worn inner chainring so fitted new chain ring. Its now sucking on the big (50T) ring. Rather than buy a new ring is there a case for filing the drive edge of the teeth on the big ring to extend its life ?

I've had several issues with chainring bolts working loose. I've now got 1 that wont fully tighten at all. The threads engage for a couple of turns, but it then simply goes slack again before nipping up. This is on a shimano 105 5800 chainset so unfortunately the bolt isn't the older 2 part...

I need to fit a new 42t 130 BCD 5 bolt middle chainring as the current one is worn to pointy teeth. Is there a difference between an 'inner' and a 'middle' chainring? Seems to be a big cost variation, just wondering if there's any technical difference that will affect shifting?

I greased my chainset bolts and nuts today for the first time in an attempt to resolve a creak, I thought it was the bottom bracket, but evidently it was not. Taking the opportunity to properly clean the inner chainring I noticed both rings were past their best, not sure it is economical to...

Was having a nosey about the inter web and noticed that single chainrings seem to be the way forward at the moment on a offroad bikes. Must make it hard to get up any sort of speed on a normal road and use a hell of a amount of effort

I need to replace the front outer chainring on my ultegra 6800 due to worm drivetrain, however I am having great difficulty sourcing a replacement chainring without having to buy the whole crankset. It's a 50tooth ring. Would a shimano 105 fc5800 chain ring be compatible? As far as I can tell...

Hi folks, in my need to do something stupid I've fitted a Campy Caentaur Carbon Compact UT crank to my Brompton. Does anyone do a kit to properly fit a single chainring to it?... ATM I've got a slightly ugly bodge using washers to add the extra width to a set of KCNC chainring bolts (slightly...
