Well done to ALL posters
It soon became useful and entertaining. There are regular posters, people who add useful info occasionally and plenty more who drop by to watch. That's fine. If you want to add news/comments it's easy to register and become a member.
RULES No personal insults. No swearing.
not resolvedThe replacement front derailleur off of el fleabay which is needing a bit of hot shim action (about 4mm worth, any suggestions as to a good material for shimming.
Or do shop repair inventories carry such items as Fd-M412 Clamp Band Adapters For 28.6Mm
TBC?
I've previously got a replacement band clamp off the shelf courtesy Velo Ecosse.
I've shimmed various things in using carefully cut sections of beer tin. If you cut as a spiral, you can get a long, constant section that is conveniently pre-coiled.
I have the old Shimano band from my Alu-framed road bike that I had to replace when I moved the derailleur over to the steel frame, which has considerably narrower tubes. I'll measure it tonight as it may be correct width for your seat tube? It's sold for a Sora, but it looks pretty similar to the Alivio one;
Ta, would have to go for the shimming option, as it's a combined one, rather than a switchable one. Gah. Tempted just to buy a new one from CRC, as in the long run it would be a lot less bother as it comes with adapter.
This is why I shouldn't play with my bike. Maybe Mikael has a point.
No, this is how you learn. Otherwise you'll never learn! The other option is that you may be able to buy a shim manufactured to the correct tolerances for your purpose. May be a more permanent fix.
Is it 2mm on either side = 4mm, or 4mm all the way around (as in 8mm total)?
I think it's 6mm total. The original item comes with purpose built converters http://www.chainreactioncycles.com/Models.aspx?ModelID=38440
Surprisingly my 99p ebay model didn't :) The ever helpful TBC says they can order in, will see what I can rustle up at home before I put them to the bother though.
I've an official Shimano band clamp adaptor-shim left over from my front mech replacement last year... I even know exactly where it is after my tools-and-hardware reorg the other week...
oh oh oh :) Can I purchase/bribe/cajole for? Even if it's not shimmy enough, I'm sure I can shim the shim.
I imagine it would take an aluminium-seat-tube-sized band down to steel-seatpost-sized-band size band. No-one else has laid a prior claim to it so it shall be made available to the claimant above. I'll tweet when I get home and can retrieve it.
Woo! I await with tweeted breath.
