Anybody running a 50x38 ?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Anybody running a 50x38 ?

Just had a CAAD9 built up for me. I spec'd all Rival level components except for the crank where I splurged for the BB30 Force model. It came with 50x34 (11-28) which was fine but when I started doing group rides I quickly became annoyed with finding myself having to double shift the back everytime I changed chainrings in the front. I picked up a 36t and it's certainly been an improvement. Now I have my eye on the 38t. The group rides are mostly flat to rolling and I haven't missed any of the climbing gears of the 34 so far.

Anyone else running a 50x38t ?

Thoughts ?

I'm running a 50X39, but I swapped the 53t out for the 50t.
11-23 casette.

What brand 38T ring are you going to get? If your front 36T ring is a proper 10-speed specific SRAM ring, you probably have real good front shifting. The generic 9/10 speed 38T rings made by the likes of Stronglight, FSA and TA Specialites can have problems shifting with 10-speed chains because the inner ring chainline is slightly too far from the outer ring.

Some people have no problems shifting with these rings, though, so you may be okay.

Yes. My commuting bike has a 50/38. The shift pattern is much, much better than a 50/34. Mine is a triple with a 26 tooth inner but I seldom use it even here in Colorado.

My service manager and shop manager both run 50x39. I have as well, though I currently have a 50x36. We're in north Florida, with some hills, but nothing particularly long or steep.

We're all old farts, and don't enjoy grinding out 53s or 52s any longer.

Wonder if SRAM will come out with a 51x34, since their MTB XX grouppo calls for the big ring to be 1.5x the small ring.

FWIW, in the SRAM 2010 dealer book, they call the following fronts to be compact (some are more compact than others):

50x34
50x36
52x36
52x38

Why not stick with the 50/34 and go to a 12/25 cassette? It would give you a similar low gear, but tighter ratios.

I would agree you may want to look at changing cassette's. The 11-28 goes, 11, 12, 13, 14, 15, 17, 19, 22, 25, 28 and causes you to have larger gaps the further you go. The 11-23 goes, 11, 12, 13, 14, 15, 16, 17, 19, 21, 23 and then you have a 25 and 26 option in between these two ranges.

I'm running a 48/34 12-26, but I climb a lot of steep hills. Shifts better than the 50/34

Yes but I like my cassette skewed at the high end....I don't get into the 22-25-28 that often but when I need it...I need it...

@Botto....doesn't take much to entertain you does it ?

I run 48-39 or 38 a lot of the time on my cyclocross bike, which I use for mostly solo road and dirt road riding. Pretty good. 48x12 as a low gear is a little low, but workable. With an 11 it works great. 50 might be a little better, but I already had the 48t FSA chainring. Shifting with rings that close is butter. Go for it.
