If one has to resort to installing a spacer under the freewheel, he/she is doing themselves and future owners three disservices:
1. Never should a spacer be placed behind a freewheel because 99% it cannot be removed (after torquing the freewheel and years of climbing hills) without ruining the hub.
2. If the rear derailleur (on the bicycle that is now using this wheel) comes the slightest bit out of adjustment and throws the chain into the area between the spokes and the reverse side of the freewheel, you now have a chain that is wedged heavily down and in between this area. Of the 99% of the times I have seen this happen, all 8 (if 32H) or all 9 (if 36H) outer drive side spokes needed to be replaced as the chain shredded them to the point where the wheel was no longer safe to ride.
3. You have left the future owner with all sorts of silly and ridiculous spacings (123.5mm, 124.5mm, etc) which he or she now has to attempt to rectify.
*4. It has been my experience (in selling on eBay for 5 years of so) that the resale value the hub with the dreaded shim is much lower (to the buyer who knows what he/she is looking at.)
As for putting the spacer behind the fixed cup in order to achieve proper chain-line, that too is very "hack." We all have (or have access to) an old Campagnolo catalog that tells us exactly how to set up chainline. Oh, and do not forget that if you put that 1mm spacer behind the fixed cup, you have successfully moved your entire bottom bracket over 1mm thereby bringing your left crank closer to the frame and moving your right crank further out. But if riding with an offset BB suits your needs then more power to you.
Ted E. Baer Where we had two helicopters, eight news vans, and over 300 policemen dressed in riot gear the other day to make sure a bunch of 17-y.o. kids didn't get out of hand. I wonder what this cost the city? Hopefully not as much as Palo Alto's $21.5 million dollar settlement with Enron........... Palo Alto, CA
