Resto trouble

(1/2) > >>

Peanut:
I've run into a couple of problems. I knackered the seatpost getting it out but I have a nice layback I want to use instead, thing is it's too skinny for the frame, are there spacers you can get?

Also the bars on closer inspection look like they've been cut down, anyone got any good ideas on how to extend them back to the width they should be?

sam hudson:
The shims that came with my Uni seat were just plastic.I'm not sure about over the counter stuff but you could always try to make some shims out of plasticard.It comes in different grade thicknesses.You would have to bend it down at the top tho (to create a lip)to stop it slipping down the seatpost tube.Its easy to manipulate tho,so it shouldnt be too much trouble.
Hopefully tho,someone will know an easier way :daumenhoch:

I would imagine that to safely extend bars you would have to cut the extention tubing to the desired length and then get some smaller grade tubing to fit inside the extentions and the original bars...and then weld the lot up.I wouldnt imagine that a straight weld would be strong enough without an insert....but then i'm not a welder. ::)

Good luck

theRuler:
sounds like you want to run an oldschool sized post in a newschool sized frame.
hmmm
havent seen any shims to do this before.
you could give alans a ring - he will know

as for the bars
once they are cut, they are cut

they are better narrower anyway, rather than yeehah cowhorns ;)

bodamus:
You can always make your own shim the oldschool way by cutting one out of a Coke tin, this way you can create your own thickness of shim.

Or if you don't want to be a cheapskate try alansbmx they probably have shims metal and plastic versions which will hold your seatpost in.

From bodamus ;)

theRuler:
the difference between old posts and new o/s posts is quite a lot
maybe make a shim using a section of a new oversized post with a slot in it?
