Dropping a tooth in the front only gives you a 1.1 gear inch on the low end assuming you're keeping your cassette the same. You're better off just getting a cassette with an extra low end sprocket than possibly compromising front shifting. So for instance if you're running an 11-25, get an 11-28 (it will give you 4.4 extra gear inches on the low end). Not to mention cheaper and easier.

Edit: Here play around with Sheldon's gear inch calculator to decide for yourself http://www.sheldonbrown.com/gears/

I run 52/38 because i spin on the flat and for the most part spin up hills. with the exception of anything alpine, it works fine. i'd run a SRAM force 11/28 cassette if it were hilly though. its a great combination.

TA chainrings are cheap btw... cheaper than force cassettes!

I used to ride 53/39, but I have made a switch recently to 52/36. There are mainly two reasons.

1) Versatility - When racing, we usually use just a big ring unless there some steep and long hills included. But when going to Italy to tackle big climbs tsometimes the 39 could a touch too much.
2) Narrower cassette - I hate jumps in shifting so I prefer 11-25 most of the time. And with 52/36 it works perfectly. You have climbing gears and also narrow cassette for flats.

And I dont know why, but I would rather change chainring than cassette. For Shimano the smaller rings are even cheaper than a new cassette.

I used to run a 53, 38 years ago. I do know with some crank arm the chain will come in contact with the tops of the crank arms. One tooth does not really help that much and you are better off to go two more teeth on the biggest cog on the cassette.

This.

Also, running 25mm tyres instead of 23's makes the difference smaller.

Black TA's look good too :)

My brother used a 38 tooth inner chainring for a Dura Ace crankset recently on a hilly ride. NW of St. Louis along the Missouri River. Almost unbelievably rugged climbs. He had already put the 11-32 nine speed cassette from his mountain bike on the road bike. So the easiest way to get a little bit lower gear was to put on the 38 chainring. I happened to own a 38 tooth TA ring for Shimano's 130mm bcd cranks. Not sure why people think TA rings are cheap. The TA Hegoa 38 tooth 130mm bcd ring is $84 from peter White Cycles. Its cheaper than a Dura Ace cassette, but more expensive than an Ultegra or 105 cassette.

I agree with this. I recently moved and because of a change in terrain went from 53/39 to 52/36. I love it. Where I live now, it's either flat or short/sharp climbs. By running an 11-25 I have everything covered, and the switch from 39 to 36 is essentially one cog in the back. IOW, the 25 now is the same as if I had a 27 before.

If I relocate to an area with different terrain, such as where I came from, I'd simply replace the 36 with a 38. I think 52/38 might be ideal for most locale.

That's because Bertie can't use his wi fli anymore. He likes to climb in the big ring and the wi fli was great for that. I am surprised Shimano have not developed a long cage.

I run 50/34 and an 11-28 cassette... No problem even on very fast group rides, plus I even have a few downhill KOMs. No idea where I'd need a faster gear, this is 70+ kph, so I just tuck.

53s come from the time when the smallest sprocket was a 12 or 13...

they do indeed. was going to say i've run 52/34 and obviously 52/36 without hassle before. 52/34 is an interesting one but the jumps from big to little ring are a little too severe...

The progression between the gears is different with a standard and a compact, it's not just about the one extra fast gear. the change in gear inches between each cog in the cassette is slightly larger when using a standard, which some people prefer to the tighter gaps you get with a compact.

for me I have no problem with 53-39x27 in the sierras (up to10km climbs between 7-10% with steeper ramps at times) and I guess the 38 giving an extra 1.1 gear inch is not a bad thing. in fact I cant see anything to lose, hell it is even one toooth lighter too :D

did anyone have any opinion on shifting performance, i suppose nothing to it if contador is running it and he is known for being very cautious in equpment selection

it will soon be time for chainring purchase so I intend to give it a go
