bent middle chain ring - will this work as a replacement

freeagent

somehow i've managed to bend the middle ring on my 2010 Boardman Sport.

Crankset is Truvativ fiveD.

can I fit a replacement from another manufacturer? like this 32T ring from Shimano?

If so then great...
However... for a while I've been thinking about ditching the outer ring in favour of a bashguard as i've used it once in the 9 months I've had the bike...
Is the fiveD crankset actually worth upgrading though?

If it is worth upgrading, I've been thinking about getting the 36T version of the above, just to give me a slightly better spread of gears, and a bashring like this;

sorry for all the questions... i'm still a bit new to all this, and don't mind spending money on an upgrade, but don't want to shell out on upgrading something that is not worth it..

cheers,

yes but you may need to take a file to the shoulders to make it fit.

for both items.

OK thanks for the reply, will go for a 36T and bashguard..

Remember that the middle ring is directional. If you fit it the wrong way round, the chain comes off really easily :oops:

I wonder how people fit rings the wrong way round. many have recesses in them for the chain ring bolt head. many are offset from the mounting face so can not fit the wrong way.

the biggest issue is incorrect rotational position.

I know :roll: some people eh pfft

Allegedly the middle chainring on M521 cranks is very easy to fit the wrong way round. It all goes together just fine *ahem*

Well why don't they make it clearer then?!

I agree if you're talking alignment.

Way facing, that's a different story, ramps and pins on middle and outers (mostly have a pin on that sits under the crank arm to stop the chain getting jammed, so you need to align the middle and inner to this postion) make that completely obvious if you only slightly know what you're doing.

thanks for the advice guys - it seems a 36T ring might not be such a good idea - as my front mech may struggle with the 14T difference between bottom and middle ring, and there could be limited benefit in going 36T anyway,

I'm gonig to order a 32T and bashring and see how I get on.

I'll try to make sure i don't get it the wrong way round!

If I had a 22t granny in 2 ring setup then I'd perhaps think about a 34/6 rear go for a 36-40 middle/outer and then with a 28t granny - well within limits.....

I run a 34/36t cassette, and a 22/32 up front, and never spin out. Not sure what you ride but it works fine for me.
