Greetings,

I have a simple question that may get answered in complicated way, or in basic terms. Any help would be appreciated

Im a fixed gear rider in nyc, rides are for fitness and fun ranging from 10-30 miles. Bridges and some parts of Central Park are the extent of my hills and occasionally defeat me. I’m 6 foot 215 and fit, not super cycling fit. I ride a 48x19 gear ratio and some point would like to get a 17 so I’m not spinning like a lunatic at 30mph, but yes I realize I’ll be walking the bike up more bridges when I’m tired.

Heres the big question though. How much effect would it be if I was able to drop 10lbs of my body and get to 205 assuming I maintain relatively same overall fitness level. There must be a calculator out there in terms of watts/speed and weight maybe even with gear ratios and I just can’t find it. If folks are trying to lose grams of their bike I imagine dropping 10lbs has to be significant right?

Thanks
