Grubee Rack Mount on a Fuji 29'er

[ocscully]

A friend of mine bought a Grubee Rack Mount Kit last week from a member of this forum and we have begun the process of getting it set up on his 2006 Fuji 29'er city bike. This kit came with the type III Gearbox. The rack on this kit had had alignment issues in the past so we started out making sure the rack was flat, and that the legs were set up properly. The mounting plate was also no longer flat so I built a new one out of 1/4 in. aluminum plate. The rack is designed to mount over the rear axle but since this bike uses QR Hubs I built a pair aluminum tabs that bolt to the fender and rack points of the rear dropouts. I've also made an upper attachment bracket that mounts to the mono stay on the chain stays. We did a test fitting of the new parts this afternoon, and with a few mods to the parts tomorrow its looking like everything is going to work well.

great work!

i have the same kit, (im mechanically challenged btw) bought new mid june and still not done. My goal is to get it running by end of August.
(I have a huffy cranbrook and the rear wheel/hub and chain/sprocket are my issues)

Please keep posting. Thanks

Thought we were going to have the bike up and running late this afternoon, but hit a couple of snags that are going to put the operational phase off until tomorrow. The new mount plate needs a bit more work to provide enough clearance between the 11t output sprocket from the gearbox and the bottom of the mount. This area is really tight even with the stock mount plate and the extra thickness of the 1/4 in aluminum plate made it so the chain couldn't make it thru the gap. In hopes of getting it operational today we went ahead and used the stock mounting plate. One of the unique things about this rack mount design is that you are able to use the leg turn buckles to raise and lower the mount portion of the rack to control the left side motor chain tension. The second major snag of the afternoon was with the throttle cable, it wasn't long enough and the cable end at the carb wouldn't allow the throttle to return to idle position. We went to a couple of the local bike shops to pick up some brake cable housing and a tandem length brake cable to make up a new proper length throttle cable tomorrow morning.

Bike is Done

Spent a couple of hrs. this morning building a custom long length (73 in.) throttle cable. Used a tandem length brake cable for the inner wire, and an oversized Nicropress fitting for the cable end. The fitting was then filed down to fit the cable stop on the carb. Once the cable was complete is was just a matter of installing it and the fuel tank and then extending the kill switch wiring. Let the test rides begin.
