Constantine, I did what you did too! I took out the chainrings without marking them! Is there any problems associated with placing the chainrings on different position than before? I started to hear some clicking sounds when I was pedaling hard after I did my whole bike maintenance, could this be it?

OOOoooops!… I did not mark the chainrings’ position in relation to the crank. ((
What should I do now?

@G: Measure your chainring from the center of the bottom bracket to the outside edge. Then measure the prospective bashguard to make sure it is larger than that distance. These measurements will be different depending on which bashguard you want to buy, as they have different ways of mounting.

I have a SR Suntour XCC-T102 42/34/24 on my ’08 Trek 4300D, but want to turn the front into just a single chainring with a bashguard. How do I take measurements so that I can get a new chainring and bashguard that will fit me cranks?

thanks…

Thanks for the help Alex.
Some of the teeth are bent forwards and are sharp, however some of the other teeth are blunt and look quiet worn down.
I’ve phoned the local bike shop, and they will replace the chainring or the crankset if necessary.

Graham, considering your chain & cassette are new, it does sound like your middle chainring may be worn out. How do the teeth look? At the end of this video there's a pic showing what a worn chainring looks like (shark teeth).

When i ride along on my 2nd chain ring, the chain slips. 1st and 3rd are fine but its only my middle chain ring. I’ve ridden close to 1500km on my bike. Should i just replace the chain ring if possible or should I grab get myself a new crankset. I recently replaced the chain and cassette after I bent my old chain. Could this be contributing to the problem?

Thanks Graham

Hi Cameron,

The middle ring would be the best one to leave on, as the chainline in that position will still allow for smooth shifting on all of your rear cogs.

I have three rings on my bike but I want to make it a single ring in the front. Is there anything I should know before i just take the other two off?
thanks

Hi Alex,

Fixed the problem, the clearance is still not that great but it won’t move and won’t rub unless the ring gets bashed.

Keep up the good work, much appreciated
