48t Chainring for Shimano Compact crank?

All

Quick question, I have just built up a new bike, and opted for a compact crank.

It's the Shimano 105 one, which I think has a 110 BCD. The rings are 34/50.

Ideally I would like to swap the 50 for a 48.

Do they exist for this crank/bcd?

I've done a bit of web searching and only seem to find FSA rings

Thanks

yes

Middleburn, TA, Shimano, Stronglight, Raceface all do them

CRC had some 48t Middleburns in the flood sale the other day for a tenner posted but I think they're sold out now

Have a look on CRC, for example

and on ebay

Many thanks, I though for a moment going compact had ruled out swapping chainring sizes

I have TA 38/48 rings on my old (1980s) dura-ace chainset which work fine.

Presumably any of these 48t rings will work 100% with my all 105 drivetrain?

I just find the jump from 50-34 too much, with 38/48 I was able to go from flat gear to hill climbing gear without shifting at the rear.

48 T will be fine. I doubt whether you'll even need to remove any links (unless the chain was almost touching the joscky wheels when in the 34 and smallest rearc cog)

I run 33(TA)/48(Stronglight) on my Utegra compact.

Thanks guys

I've ordered a 48t Stronglight chainring, £18 delivered, from the link above.

Hopefully I'll fit it this weekend and achieve gearing perfection!
