Current setup is a stripped down Vilano aluminum roadbike (first bike, got it on craigslist for $25 - so I can't really complain). I've removed as much useless junk as possible. Specs are:

- Shimano Tourney 21-speed setup.

- 50t/xx/xx chainring

- Highest rear cog is a 14t

- 700c/25 front and rear tires (cheap tires and stock wheels)

- Steel front fork

- Aluminum seat post

- Steel crank arms (pressed-on square pattern)

- Weighs approx 27 lbs.

- No water bottles, nor water bottle brackets


So I've been riding this thing for a couple weeks now, and yesterday I finally put a computer on it to see where I'm at. Well, on flat'ish roadways, tucked on the down bars, I can put a lot of oompf into it and managed to only push like 25.4 mph (50t/14t), but don't have cadence numbers on that (felt like a lot lol). I can approximate it using math, but I have no factual data. I'll double check the calibration of the computer for the speed reading, but I'm assuming it's accurate the way the instructions suggest I set it up. Without detailing cadence I doubt that's useful info. But I was surprised at the numbers. I've watched and noted people maintaining 26 and 27 mph over lengthy rides, yet they may be chugging a 53t front ring and 11t rear cog for gearing. I'm in pretty decent shape, and have been distance running for years (middle distance strength training), and I'll also humbly admit that high intensity cycling isn't exactly easy. I'm willing to accept that I need to condition more towards cycling, yes.


The only other rear cog I can get for this setup is a 13t, which isn't much, but is worth a couple mph assuming equal cadence. I can actually get as gianormous as a 58t front ring lol. Lastly, I'm willing to lighten my beast up some, also - but I feel this benefits acceleration more than anything. I mean, I've got less than $100 in it so far, so i'm not complaining. Eventually I'd like to do some local races, but otherwise would like to ride faster bc speed is kinda fun.


With all this, what can I do to get more speed ? Cheers!
