rear rack mounting how-to

[Jim Flom]

I just got a "Giant rear rack for hybrid" that I want to mount on my fixey
(c. 1980 Centurion touring frame) as part of its evolution into urban
commuter. The bike has two seat stays and a (vacant, at the moment) brake
bridge. It has no other bosses or hardware on the seat stays.
I really just need to get the front of the rack mounted onto the seat stays.

The rack looks a lot like this:

Thing is, the rack has no instructions, and has a bunch of parts that I
can't figure out what goes where.

1. 4 screws with washers
2. 2 U-shaped brackets with a hole on the bottom of each and slots that
look like they'd nest on the rack. The screws are too fat for these holes.
3. 2 arms like ice hockey sticks and a hole on each blade. The screws
would fit these holes.
4. 2 more arms with rubber tips on one end and a hockey stick blade with
hole on the other. The screws would fit these holes too. There's a bracket
thing-a-ma-bob that slides up and down on them and has half-cylinder jobbers
inside the sliding bracket thingies, also with smaller holes as with 2
above.

Sorry for using such technical language. I really just need to get the front
of the rack onto the seat stays with something better than duct tape. :-)

The hockey arms screw into the bottom of the rack. They should be
slotted so you can adjust the angle of the rack. Usually a philips
head bolt goes through the top of the rack to a nut. Use a washer with
the nut if the bag has some lock washers in it. The arms then bolt to
braze ons on the seat stays--but as you don't have braze-ons, you need
to get some rubber coated p-clamps. Find 'em at hardware stores or the
bike shop. Attaching the two main stays should be self explanatory.

Here's a rack with arms in place:

Thanks for the tip about the rubber coated clamps. All secure and ready to
go.

another way is bolting an aluminumangle to the rack with 2 holes for a
long legged u-bolt, the curved end wrapping around the seat tube. Seat
tube needs a half section of bike frame with a nub or stop on it for
the u-bolt curve to rest up against. Linseed the seat tube if steel
against rusting.

half section of bike tube maybe an inch inch and a half long duh
