What size Big Ring on your double?
Just wondering what size Chainring most of you ride with and why? My bike came with an FSA SL-K Light Crank with 53/39T 130BCD Rings and I have been thinking about changing the rings out for some Praxis Rings mostly because of the look (bike is black, everything is black, I like the black) and the good reviews on their performance too. Now that I really started to think about it, I wonder if I should reduce the size of the big ring to say a 50T? My thinking is that although 95% of my ride is on the 53T Ring, I'm usually in the middle of the cassette, never on the 12T. I also might find that with the smaller Big Ring that I will not need to switch to the 39 as often on climbs? I should also note that my bike has Ultegra Di2, I'm assuming that a 50T Ring is compatible? Any info would be helpful, Thanks!

I didn't think there was much climbing in the Orlando area. I still have my standard double and I like it. The hills around here are not enough for me to change it really. If I had the funds I would get a backup bike with a compact for when I travel to do more challenging rides.
You will be fine with either. If you are happy with the standard, there is no need to change that. If I were you, I would try to find a friend with a compact, or even go to a bike shop or performance and ride a compact before purchasing compact rings. |
Compact
50/34 11/28 cassette |
Compact 50/34 with 12-25 cassette. Moving to 11 speed 50/34 with 11-28.
|
53-39, 11-26 daily wheels, 11-23 race wheels
|
Htfu. Use the rest of the gears on the cassette by building bigger guads. Dial it up past 400 watts. Then get a bigger big ring.
|
If I lived in Florida I would run a 50T or even a 48T
|
I use a 50/36 and 12-27. The relatively wide cassette allows me to stay in the big ring on rolling hills while the 36x27 combination is good for climbing ugly hills. The 50x12 top gear is shorter than common, though. This also allows a 14t gap in the front, which aids shifting.I really don't get why this isn't more popular.

Vintage Racer has - 52/42 - 12/23 (6Speed)
Endurance training bike has - 50/34 - 11/28 (10spd) Full Race bike has - 52/36 - 11/28 (11spd) On the full race bike: I think I might go 50/36 or 52/38. May change cassette down the road to 11-26. Lots of climbing around my neighborhood though. |
Commuter hybrid trek 7.2: 11-27 (28,38,48)
road bike: 11-25 (50-34) cyclocross bike 11-25 (36,46) |
52/36 Sub compact
12-30 rear (ran a 11-28 last season) |
53/39 double, 12-27 cassette (9 speed). Seems to get me around SoCal pretty well.
|
53-45 ................. 45 is a perfect hill climbing gear
|
HTFU is right, and when you're able to dial it up past 600w, get a 55t:
|
53/39 x 12-25 daily wheels, 11-23 crit wheels.
|
50/34 compact. 12-23 10 speed for most riding. 12-25 for hillier territory. (I like the 1-tooth spacing on the former for most of the cog range that I use.

A 50t ring has a 110 bcd, and would not be compatible with a standard 53t 130 bcd crankset.

50/34 with 12-28 (11speed)
I do a lot of hills and I want to keep the rear cassette fairly closely spaced together. Hate big gaps. I slightly miss the 50 / 11... but I'd rather give up the 11t for the 16t. 11-28: 11-12-13-14-15----17-19-21-23-25-28 12-28: --- 12-13-14-15-16-17-19-21-23-25-28 |
@lsberrios1 I love me some old school.

Flat ride, standard and 11-23
Climbing ride, semi compact and 11-28 Also have a 12-25 as my everyday which goes on the semi crank. |
The road bike rings in the garage right now in some combination or another on a bike or ready to go on a bike:
34,36,39,42,50,52,54 with 10spd cassettes of: 12-25 11-25 11-26 12-27 11-28 I think I may be forgeting some. But, those pretty much cover it for me. Personally, if mostly flat, mostly on the big ring of 53 and mostly in the middle of the cassette, I would keep it that way. |
