46:15 ~ 81gi

After the 7710s go on,

48:15 ~ 84gi

I ride this on the street. When I finally man up and head to Penrose, I definitely want to try bumping up to the 90gi range and give that a try.

I've tried 48x17 and 50x18 for the riding I've done around my area. They are essentially the same. I tried the latter out on the velodrome this past weekend and it was definitely too low. The 50x16 that I'm trying out next week will be something different for me.

I just messed around with 70GI, and realize I don't like it for sprinting. It's amazing for climbs though.

I'll drop the rear to 16 (putting it at 82gi) sometime this month.

Settled on 58 GI for the winter, liking 65 GI now. So I voted for 60-64.

I just purchased a 15t, so I'll be pushing 46x15 by next weekend; we'll see what an 11 GI increase feels like on the roads.

42x17 in fixed mode = 66.14 gear inches
42x18 in singlespeed mode = 62.46 gear inches

I'm a spinner, my preferred cadence is usually between 100 and 110 rpm.

48x16~80gi
I want to eventually change the gearing lower cause it leaves me with only one skid patch, but I have a few steep hills I go down that I couldn't imagine with lower gearing.

I really need to work on getting a higher cadence though.

for reals though, 42/15t here.

i have an 18t on the other side, but don't use it as much now that the socal road season is in full swing.

once i get to the track i have no idea what ratio I will need.

Ordered a 15t cog for the track this Saturday. Hopefully it gets here by then.

Couldn't accelerate fast enough on 48/14. I think 48/15 will be a lot better.

48/14 for about a year now, but I just picked up an EAI Deluxe 17t... so 48x17 here I come. Trying to climb hills a bit easier and practice my cadence. Feel like 14 is just too much for me now even though I'm in love with the top speed I get from it. Oh well.

i told you so.

48/16 for warmup and training races
48/15 for beginner racing
49/15 for beginner racing
50/15 for beginner and/or intermediate racing
47/14 for intermediate racing
48/14 for intermediate and/or advanced racing
49/14 for advanced racing
50/14 for advanced racing

This is a common gear progression at our track for beginners. As you get stronger you will be able to push bigger gears. Notice how the 48 gets lots of use. If you already have a 48, I suggest buying in this order:

1st Purchase: 48t + 16t + 15t
2nd Purchase: 49t
3rd Purchase: 50t
4th Purchase: 47t + 14t

Those gears will take you through about 2 seasons of racing with LOTS of gear combination possibilities.

You were right. I admit. I was fine keeping speed, I just can't spin it up fast enough. One day.
Also, that chart is ****ing fantastic. Thank you, and Carleton.

I have a 48t front chainring, and 13-17t cogs. (don't ask about the 13t, lol)
If i run into some cheap 130 chainrings on CL i'll pick them up. I'm not going to invest too much in chainrings until i get a proper 144bcd crankset.

That's what I would do.

I'm sure you'd be fine with 48/16 at a training session. I run 49/16 at them. No real need to go higher.

32x15 = 62 g.i.

I really wanna go to a splined crankset to get an even smaller chainring + cog.
