Compact to Standard adaptor

Rojales

Hi,
I have a compact Shimano 105 chainset, is there such a thing as an adaptor to fit standard chainrings!!

Thanks

Nope, but there are quite an array of chainrings to fit a compact that may give you an option that will as near as dammit suit your needs. I think the max is 38t for an inner ring and 51 for an outer.

Here's a 56T outer:

(plenty others larger than 51, indeed 52 comes as standard on a lot!)

and plenty of inner's larger than 38 e.g.

which goes up to 44T

sell the compact and buy a standard? most people want a compact these days

the new shimano 11 speed chainsets have one BCD that all the chainrings fit to (this chainset works with 10 speed, 9 speed too)

I do have a standard 39/53 with 170 cranks but I have had problems with my knees so brought a new compact chainset with 165mm cranks which has cured my knee problems, but having a compact I find that i'm forever changing gear than when I had a 39 inner. So was hoping I could fit existing rings to the compact.
