Changed my mind chainset, help needed

BMKN

I currently have a FSA Tempo chainset, I wish to upgrade to a standard chainring, I want to just buy two new chainrings, I had bought 105 chainrings but found they are not compatable, I will return them, however what chainring do I buy, I am completely lost with what is compatable please elp

If you look around (I'm assuming you have a "compact" double with 110mm BCD) you will find that FAS do 39 and 52 tooth chainrings to suit. Here is one example - they're called Pro Compact rings.

I assume that you have a compact double chainset, and you want larger chainrings?

If so, you need some 110 BCD chainrings to fit your chainset.

Praxis works are a company that make larger ratio rings in this BCD. They aren't cheap, but they are excellent.

For alternate chainring options you need to find 110 BCD rings in the sizes you want. I personally run 50 outer and 36 inner.

A supplier with a wide range of chainrings is spa cycles. For example £10 for an inner stronglight ring:

£14 for an outer ring:

The outer rings do have pins to help shifting.

Why do you want to change to a standard chainset and why do you think it is an upgrade?

Doesn't really matter why he used the word upgrade, or why he wants to change gearing. The question was what rings to buy that would fit.

I'm using Sram red 52/38 rings on my 110bcd chainset. Spa cycles is a good shout on somewhere to buy rings though.

I think the OP doesn't understand what standard and compact cranks are. That would explain his thinking that either / or was somehow an "upgrade".
