Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

I can run 5 cogs-63, 66, 70, 75, and 80 gear inches. I ride the 70 and 75 most of the time. I just did an extremely flat century (400' of elevation) with the 75 gear inch. Riding with a fast group of geared riders for the first half of the ride the 75 was perfect. Riding by myself or with one or two other riders the 70 would have been better. Could have flipped the wheel but was lazy. I found out that a long flat ride on fixed gear is hard. I've come to appreciate rollers and short climbs!

i'm running the same gear as you for road right now, but i was thinking of switching to 47X17. how do you like 50X15 for track? theres one 40mi away and when i get a track bike i'm definitely checking out some classes. 50x15 sounds perfect for me. i'm 5' 8" 150 local bike shop if it matters. i used to run like 82" on the street and loved it, as long as i had a brake. i dont ever remember hills being too much of a bother. 69" seems too low though but for towning around brakeless its perfect. idk, i guess how you likin that 50x15? that really sounds like something i would like for track racing

48x17 on the road.

48x15 on the track (first season).

50t for up front is next on the list (track). Also have a 14t that I haven't worked up to yet.

I am also 5'8" and 150 lbs.

50x15 is great for me at SDVA, which is slightly lower then avg, but I'm a spinner and san diego is a slow track. If your track is indoor and wooden it will probably be faster and warrant a bigger gear, but 50x15t is a great starting point.

54 x 16 on the streets and hopefully, when I get home, on the track as well. Thinking about picking up a 14 just for fun to switch out once in a while. 54 x 16 is actually not that bad. In fact, I don't know if I could go back to 48 x 16. I like the top speed. I'm a little slower on steeper hills but average hills I'm okay climbing. Should get a little better once I get new pedals and shoes too.

I've already mentioned this on some other threads but currently running 53x16 @ 87 GI. I'm actually thinking about gearing down back to 46x16 because of the wind and my legs forgot how to spin after half a year of mashing.

Well I know that I'm not doing it for style, my commuter looks dumb (mini aero bars, aero brake levers, water bottle cage, anatomic drops, freewheel, etc). I purpose built my cheap commuter for a high-ish cruise speed since I commute to work on a long flat straight and I hate waking up early.

Plus, I only weigh about 135, my starting inertia is far less than most riders.
