[Closed] Idiots Chainring Question

You can use any brand who make a suitable chainring with a matching bcd ( bolt pattern )

you don’t mention which version of crank you have so it’s hard to give recommendations.

However. A 2 tooth jump will make pretty much sod all difference VS a slight increase in leg speed ( RPM )

As long as the BCD matches and the offset is broadly comparable, yes.

You'll need to get the 4 bolt asymmetric bolt pattern rings.

and use  http://www.gear-calculator.com/# to see how much difference it makes.

Thanks Both. Four bolt crank, not sure which version. Would you recommend the jump to 36t then? I just have concerns about the other end of the cassette when climbing.

Only you know how hilly it is and how you currently cope.

Don't forget you will need a longer ie new chain

Very and slowly 🙂

Good shout on the chain Murray. I didn’t even think of that for some reason.

Anything with the 96 bcd will do

ive just put an ubercomponents oval ring on mine

Don’t forget you will need a longer ie new chain

If only going up 2T then it's unlikely you'll need a longer chain.  2T would need an extra half link, which you won't be able to make work on narrow wide 🙂 .  4T would need a full link.

If the chain is about right and not on the tight side now, an extra 2T won't matter.

There are two 96mm BCDs a symmetric one and the Shimano asymmetric one.......

Just check what it says on your current chainring - 104 / 96 etc. Shimano thought it was too easy having one standard - may as well have 3.

Thanks everyone

32-36 is quite a jump, Around 12.5%.

do your sums on a gear calculator, you might shrug that difference off no problem, but you might not.

it would be a big difference for me, however I’m aware that im quite sensitive to small changes.

To add I think I’d try the 34 first if it’s very hilly where you are. You could go on sheldon browns gear calculator to compare the different options too.
