My LBS is a small appointment-only deal. Yet when discovering that problem on the just delivered MTB he headed straight to his display wall and picked a handlebar holder that fit. I did have to mod it because it wasn't sturdy enough for my riding, maybe because of the big 28oz bottle in there. Underneath I placed old bicycle tube which keeps it from rotating although the big bolts can be torqued down hard and the handlebar is steel. The MTB has made a few unplanned landings onto that holder and it still lives. -- Regards, Joerg http://www.analogconsultants.com/ |

The argument was that this would destroy the perfect chain line of the original three piece BB. Now, I have changed back and forth between the original square tapered axle to the outboard bearing BB and to my recollection the chain line didn't seem to change noticeably. Over the weekend we took a trip "up country" to visit some of my wife's relatives and as we used my wife's car she drove. It is about 250 Km, one way, so I had a lot of time to think abut things and one of the things I thought about was how could I change bottom brackets with no appreciable difference in chain line. This morning I turned one of my bikes bottom up and did some measuring and it turns out that with the old fashioned three piece BB there is slightly over 10mm clearance between the inner edge of the crank arm and the outer edge of the BB. The outboard bearing "flanges" measured 12mm in thickness and the old sty;e BB flange is `1mm.. Thus the changing from the old style to the more modern BB results in very little, if any, difference in chain line. Certainly less then the difference between two cogs on the cassette. Granted that bicycles are all different but the above does explain why I, after switching from one type to the other, and back again, have seen no noticeable difference in chain line. The discussion you were referring to was about Shimano 600 gear which is what I have on my road bike. The clearance from the inner edge of the drive side crank to the outer surface of the BB is 3mm. Now assume your 12mm measurement minus the 1mm that the regular cartridge BB has. That's already 11mm of chain line offset. A lot. You could reduce the clearance to 2mm but that much wiggle room you really need for square taper and that would still leave you with a chain line 10mm off from where it was. On my previous frame, I migrated from Campagnolo square tapered BB & cranks to Campagnolo outboard bearing BB assy, and the chain line didn't shift 10mm. Why do you think you are special? Chainline errors are entirely from not using the manufacturer's specified parts. Only a complete idiot would pull a functional spark plug from a V8 and drop it into a 4-cyl Asian econobox. Yet people mix arms and spindles which are ridiculously incompatible every day and then ride over here to complain that the crank's no good. Oy! p.s. Almost all derailleur systems will work well with +1mm/-1mm chainline error. Few can accept 10mm either way, that is a very large distance. I think I would have to be a bit picky here. A Big chain ring to a small cassette cog is going to be about 21 mm out of line, assuming that the chain line was initially aligned, big ring to 5th cog of a 9 speed cassette, and it still shifts. But, of course, if the chain line was initially 10 mm out of alignment then certainly shifting would be a bit "iffy" at least in one direction :-) On a triple the middle ring is aligned with the 5th cog.
