new problem

I was looking around tonight for a new rear sprocket and all I could find was 40-41 and 42 tooth. With my 15 tooth front that would be crazy rpm's on the highway. BTW I'm using a gs 1100 spoke rear wheel with my gs arm. It's looking like I will need a custom rear sprocket. Anyone have any recommendation? I will probably do a ton of highway/freeway riding this upcoming summer and want the rpm's low. I'm thinking maybe a 15/31 set up or maybe even 16/32 (liberal speed limits in Montana). :woohoo:

and all I could find was distressing info about how a lower more relaxed rpm highway cruising speed wouldn't increase highest attainable top speed, but might well lower it, and definitely take a lot more time getting there.

But on the bright side, the s-l-u-g-g-i-s-h new acceleration won't cause anymore soiled undies (unless trying to hurriedly pass a semi without a couple of downshifts). :laugh:

Good Luck!

no,no,,he must have sat in some coffee....

What size pitch do you need? I can see what I can find. Also if you have to can you go with a 17t front if available?

Later, Doug

I'm going with 630. Won't I have to grind some clearance with a 17 tooth?

I bought a rear sprocket from Rebel Gears. www.rebelgears.com

My 650 originally had a 13 / 33 gearing with 630 chain. I changed the rear to 26, keeping the 13 up front. The 2:1 ratio works well on the highway. The 650 starts to load up a little above 85 MPH or perhaps 75 if there is a strong headwind. With a 130/90-16 tire, it runs about 79 MPH at 5,000 RPM.

With its greater torque, your 1000 should have no trouble at all. Good luck.

Might enjoy not searching for an imaginary 6th gear.

But don't go for pinks.

Good Luck!

hey that is the truth...my girl knows nothing about bikes and she sometimes asks me after a ride what i was doing shifting again on the freeway.....Patton wrote:
