Shimano Chainring Needed


Recommended Posts

Hi All.

 

I have a Shimano 105 chainring set with a 53/42 set up. I am looking for a 39 inner ring. It is a 5 hole bolt configuration and dates from the late 80's.

 

Any idea where I can buy or swop?

 

Thanks Johan

Well if nothing else I was thinking the 42 ring. If I cannot swop I will have to buy.

 

Here is my problem. Bike dates back to late 80's. I rode it like that until 1999. Upgraded to STI levers and new rims with a 9 block cluster. Cluster is from 18 to 21. Front 53/42.

 

In between I mostly rode mountain bike but want to ride on the rode again.

 

Back then I was strong enough to turn the 42/21 on all the hills I rode on. Now the will is there but the legs suffer.

 

So I need to go to a 39/21 as it looks easier to fix than to look for a 9 block cluster.

 

Thanks Johan

Look for 2nd hand cranks,it will be cheaper than chainrings.btw you still get 9spd cassettes.

Thanks. Came right. My LBS ordered a 39 blade based on the number of the crank. Received it this week and had it fitted.

 

Now I also have granny gears. LOL.
