Just putting a chain reaction order together and have come to chain rings. I've currently got a 105 with 39-53 chainrings. On the current chain ring it says 53-b, so I click on 105 chain rings and they only do a 52-b. I'm happy with the 53 so can I just order a 53 ultegra chain ring to use on the 105 cranks or will I have any problems with this?
On the 105 list it says you must use A with A and B with B but doesn't say this on the Ultegra chain rings, so I'm guessing there will be a problem.
Why? He isn't increasing the number of teeth, and one link extra on the chain is not a big weight to carry.
52 and 53 swap isn't it? I know the difference would be very small, but there would be a geometry change.

Nah my poor explanation, I'm using a 53 (105 chain ring) now and want to stick with it, but they only do a 52 in 105 chain rings at chain reaction cycles. What I want to know is, if I buy a 53 Ultegra ring is it compatible with 105 arms?
Is it just a matter of BCD (orPCD) in when staying within a brand? In this case Shimano.
My only experience of buying an aftermarket chainring to date admittedly was a very cheap Rocket chainring off e-bay - with the dual 110/130 BCD bolt hole patterns.
I bought it to fit to a Shimano Sora 130 BCD crank and had to file a few mm off each mount lip - as even though the bolt holes lined up the crank spider shelves were too shallow for it to mount flush. Don't think I'd recommend Rocket Rings now anyway very cheap & nasty.
Do you enjoy talking in circles? Love arguing over silly semantics with like minded people?

Its the BCD of the ring that you need to look at to see if it will fit. I bought an Ultegra large chainring thinking it would go on my SRAM cranks (blond moment) and when it wouldn't I did the research...I think most are 110 BCD.
P.S I went straight to Ultegra, price between 105 and Ultegra was almost negligible. DUra-Ace, well thats another story !
