Rear sprocket teeth number

42t is standard, if you had the option to fit a different tooth count, what would it be?
I know some would like bigger and some smaller, personally for me the 42T is fine for normal road use. I always have the option of changing gearing by the many different size tranny sprockets.I'm not talking about quick change rear sprockets.

42 is fine for my street use. Short to tall overall gearing is available with fronts. I also don't see the big yank for: A) replaceable sprockets; $150 for a drum/sprocket every 20,000-40,000 miles isn't so bad. B) a cush drive hub is nice, but for street use, I'm not convinced that the uncushioned power pulses are as destructive as commonly believed.

I like your work, just my .02 as solicited. Cheers :mrgreen:

Silly question for real Commandos as there is only 42T so what you are really asking is what others like in other brands and eras cycles which can change rear sprockets, which more silly because rather few venture beyond thrilling public operation so pretty much stick with factory issued ratio. When I fttted Norvil's teeth ring I discovered there is no room to fit little bit bigger OD sprocket as it fouled the swing arm or shcoks. I'd want ~65T for the partking lot and pasture stunts, 50's for the hill climbs and 1000 ft drags, 40's for road race up to 160 and 30's for land speed events. But this is not for a real Commando. I posted references on chain link/sprocket phasing for least wear and tear if we had our durthers a long time.

Count these teeth - which is about a dozen T OD more than allows fitting the drum into a real Commando.

It probably isnt so much the power impulses but rather sudden loads
like brutal downshifts or wheel leaving the pavement and then
catching sort of loads. Otherwise Id say there is a reason modern
bikes have big cush stuff in their rear hubs.
If you ride reasonable distances at reasonable performance
levels it may not be significant.
But Id go for it, if only because of the worry factor. It cannot
hurt.

its the ringing metal on metal repeat vibration impacts the cushions are needed to dampen, not clutch drop drags and tire skipping down shits though that sure would accelerate the breakage. The meteorite Man of Discovery Channel fame is a local boy in Kingston, he's got a big watermelaon size iron based meteorite ancient Africans used as a pounding surface since was by far hardest thing in their world, he sectioned it to reveal the reason one surface was more flattened out, the whole thing had been deformed to point the outter part had been rolled under like the two curls vortexes of a paddle stroke in water, just found the zillions of times of hand pounding vibration slowly mooshed it like clay. As the edges curled under and around you could see the internal cracks formed to allow the deformation to continue. PIcture a mushroom cap with edges curled back under but bigger and tougher than a shop vise. Its takes longer than a few generations to beat an anvil into mush but it sure will over a few civilizations usage. Likely only take a handfull of microns of compliance to get just elastic deformation instead of plastic deformation till failure. Oh yeah my log splitting wedges get like this too on a small scale.
