Starting 1st build - Grubee Starfire - sprocket kit

Hey Jav, for a while, I did a bunch of 68 spoke wheelsets. They were a Blue-eyed sollanovich! BUT along the way I found that if I downsized to 10/32 or 12/24 bolts, then I could have more leeway in aligning the holes.

BTW yes most were the old 5-holes (which I used to pay 8 bucks each to have the center turned to 1.5 from 1.4) but that last couple I did were 9-hole (still the math is wrong!)

Consider nice washers, good quality American hardware, and smaller bolts all around so it will still be reasonably balanced (IF that makes any difference.

Mike

Thanks Mike. appreciate the input.
 
Jav...is it a cruiser or multi-speed ?
I have a heavy-duty coaster wheel I could trade or something
brake arm is already bent for sprocket clearance

e-mail me...pm's are turned off

Bill, multi speed. (MTB - 8 speed setup).

Kinda on hold with my build for the moment. Just ordered the front mounting kit from sick bike. the down tube dia. on this Trek is very large.

must be pretty standard fair for MTB's to have 32 spokes. I'll also hit a few garage sales, and goodwill, to see what I can turn up. :rolleyes:

I may go with a smaller bolt setup, as Mike suggested. (but use a good American quality hardware).

thanks for the offer though!

Got my front mount kit from SB today. Fits up fine on the downtube. Yippee!!!! I'll be building up this weekend. (I'll take pics...)

still debating what I'll do for the rear wheel. either 9 smaller bolts for the existing 32 spoke, (US grade kit). Or, I go with a new 7sp, 36 spoke wheel. But I'll end up using the rest of 8 speed drive train, with the exception of the cassette. (needing to buy a 7sp).

Man, this totally stinks... I got the SB front mount kit. I took out the front mount studs, but the SB front bracket doesn't line up on the drilled holes. Their site said center to center, from the the studs, should be 1.6". My 2008 Grubee Starfire Gen II looks more like 1 15/16's....

My bad. I thought the Grubee would be standard for this kit, (not knowing any better).... Now I'm back to square one. No way to get the front bracket mounted to the engine. the rest of the SB mount fits the downtube just fine though...

bummer... was planning to build it up this weekend.

the center bolt to bolt for front mounts are 1.57 inches or 40mm. this is for 48cc engines and simular sizes. maybe the sbp mounts are for 66cc(80) engines which sometimes have mounts for larger bike tubes.
