Rebuilding the Rans Stratus, need a larger chainring...

Hi Folks,

Well, I have pulled my Rans Stratus out of storage, and started a rebuild. She looks pretty good, but I am refreshing a lot of the
parts now. Fresh Town n country 26 inch on the Back, but the Maxis 20 inch up front looks fine. New 9 speed chain and Cassette,
and a fresh Battery Pack. Making the jump from 24v 16 ah, up to 36 20 ah this time. Motor and controller can take it. Got a fresh
cycle analyst on board as well, still need to mount up a magnet and set my wheel size for speed.

Tossed it together and took it for a spin. Seems pretty solid, chain skipped a little on my high gears. Might need some more wrap
by adjusting the derailleur. I knew it was running pretty well when a motorcyclist gave me a wave from his monster Harley, or
something. Felt like I was up and over 35, maybe 40 miles per hour. Smooth and steady. But, My pedalling speed was too high.

I think I need a larger chainring. I wonder if anyone is making some 60 tooth, 110 front chainrings these days?

Thanks, Josh K.

Vuelta will make up to a 63T, last time i checked

Yeah, great guys, thanx! 62 would be perfect. I have a 72, but it drops my cadence too low.
Might have to run it for a little bit anyways, and see how it matches up. I may be running a
bit faster now with the 36 volts, maybe running a lower gear. It's been a while since I had this
machine up and running.

Jesus flipping christ. You've gone full aero.
What are your watts at what top speed? I have to know.

Thanks, Well, at this point it was about 13 watt hours per mile at about 25mph, on Portland International race track.
I ran against Bill Bushnell on that day. Great ride, fast and smooth track.

24 volts, Astroflight motor, Castle controller, coupled to a Boston Gear helical cut gear reduction, 110 psi...
24volt,20ah A123 lifepo4 pack.

But, today I have no windshield, and have bumped it up to 36 volts, over compensating with current, soo it will be more,
for sure. I am looking into recreating a tailbox to reduce my drag. But, not sure that I can spring the 500 bucks for a wind
wrap again...
