1x, 2x, 3x chainring - does it matter?
I need to replace one chainring in my 3x9 setup. One possible option I'm looking at says it was made for 2x setups. Another option says it was made for 1x. They have the correct tooth count, BCD, and bolt layout. How much does this matter if the…

Why will some chainrings fit 7s-12s while others are meant for just 10s?
When looking for a chainring, I see that Shimano specifies whether it is for 2x or 3x. I'm guessing that the pins (protruding rivets) on the former will be on one side only, and on both sides on the latter.
They're also labeled "PCD", but the…

Why use 54T (or bigger) chainring?
In time trial races, I see people are using these big chainrings. Is 50/11 combination doesn't give enough top speed? What's the real advantage? I can only think of the negative, which is it makes the speed difference between two cogs wider.

Can I (easily) change this chainring?
A while ago I bought a fairly cheap bike - a Pinnacle Lithium 1 from Evans Cycles in the UK. It's dangerously close to being a BSO, but I really enjoy riding it and have no regrets about buying it.
Well, almost no regrets because I find the gears…

Are narrow-wide single chainrings compatible between 9, 10, 11 and 12 speed?
I am planning to convert my bike to 1x12 setup. Since it is an old bike I want to keep it as low budget as possible. I am looking to keep my existing BB an crank. I have read multiple posts about people just dropping high and low chainrings from 3x…

What should I upgrade first?
I just got a new basic hardtail bike. I want to get better, and it’s not the best bike, so I want to upgrade it. I was thinking about changing the gear set up to 1 and 11 speed rather than 3 and 8 speed. I go out about mountain biking twice a week,…

Chainring rubbing frame after replacing
I replaced my Ultegra R8000 inner chainring from 36T to 34T. After installing, I made sure there was enough clearance between the inner chainring and the chainstay and spun it to make sure all is good. However, after today's ride, I realized that…

There are some 5-bolt 110mm BCD double cranks out there (FSA Tempo Adventure) that put the large ring on the inside of the spider tabs. I want to figure out a way to use whatever 110mm rings I want with them so I'm not tied to a specific, hard to…
