Re: [RBW] Re: 40/24 double mod on Bombadil
I just got my Hunqapillar back from the painter last week, and today my LBS installed the headset, BB and crankset. I decided to install the stock Riv 26/40, although may go down to 24 in the future. The thing is, the Phil BB had to be shifted to the right all the way, with the left side flush with the BB shell/frame in order for the 40 ring to clear the chain stay. In fact, there is about 1mm between the sharp teeth of the chainring and the chain stay. Do I need to up to a larger BB spindle? I think I have a 111, so next size up is 113. What do you guys think? Do I need more clearance between the ring and the chain stay? Actually, the 26 is also very close to the chain stay. I used to have a 24/36/46 before.

Yes, I do think you want a slightly longer BB when you switch from a triple to a supercompact double.

Re: [RBW] Re: 40/24 double mod on Bombadil
I call this sort of gearing subcomact and like the switch to 38/24 on the Fargo (from a 46/36/24 triple). I lose some of the intermediate gears but have the same range and, more important in this case is that when moving from smooth, flat surfaces to sandy, hilly surfaces I don't need to switch between outer and middle. I simply swapped a 38 for the 36 and a bash guard for the 46. I switched from a 7 sp (for Big Apples, 16-18-20-22-26-30-34 or suchlike) to 8 speed (ditto: 13-15-16-17-19-22-26-34). It would be even better with 9 speeds and a 22-25-29-34 progression (Big Apples), but not so much better -- for my purposes -- to be worth the hassle of seeking out the needed spacers and cogs. I gear slightly higher and somewhat closer for the Kojak wheels: 12-13-14-15-16-18-21-26. I moved the spindle to the left by a couple of mm so that the chain tracks pretty straight between the 17 and 19 t cogs (65 and 58 gears; on the Kojaks: 15 and 16 t, 69 and 65). Patrick ain't it fun obsessing about gearing?

Re: [RBW] Re: 40/24 double mod on Bombadil
You mean shorter, right? -- and that only if you use the outer and middle positions. If you simply remove the outer, there is no need for a new bb at all since normally a middle ring is centered on the cassette already. (In my case, I had a triple biased toward the left to allow me to use the outer (46) with all (7) cogs; when I ditched the 46, I moved it back to the normal triple position with the middle -- now outer -- once again centered on the cassette.
