can i change my 53 tooth chain ring to a 50 on a regular 9 speed ultegra crank?

Yes.

I have a 50T TA outer on mine - from Branford Bikes - with a 38T Salsa inner ($22.00, ordered through LBS). Otherwise, all Ultegra 9 speed.

Shifts as well as it all did with the 39/53 Ultegra comes with. All I did was drop the front derailleur a fraction to match the smaller outer ring diameter.

I am also using the 50t TA ring.

A better option, though more expensive, is to go to a larger cassette. Say you are running a 12/21 with your 53/39. Change to a 13/23 and you will have roughly the same range as your 50 with the 12/21 as well as having a smaller climbing gear (39/25).

Hi TF
Funnily enough, I run 13/14/15/16/17/19/21/23/26

It's an amalgan of Shimano 105, Ultegra and SRAM cogs, which co-exist quite happily.

I got my first cat licence in 1973 on a 52 x 14 and find that spending 30 years out of cycling since then hasn't improved my condition to where a 53 x 12 is essential to my happiness <VBG>

I can't help messing with stuff like this - when I did this cycling thing seriously, you could go into a bike shop, buy whatever size chainrings and rear cogs you wanted - as opposed to now, where our gear ratios seem to have been decided by a marketing suit.

Regards

For sale - Ultegra 39 & 53 chainrings, 9 speed, one owner, extremely low yardage...

My commuter is a 39/48 using Salsa rings on a mid 90s Dura ace crankset. I used to have a 50 big ring but decided to go smaller when it needed replacing. My commute is relatively flat with two climbs that can be done in the 48 big ring and a 12-23. I spin out at about 33-34 mph and I don't need to go any faster than that while commuting.

Why not just go with a 13-25 or even a 14-25 cassette?
