Alfine perversity
My latest project, "Urbi et Orbi," is ready to ride:
http://wiredcola.com/content/urbi-et-orbi It's a late-80s Pinarello with an Alfine 8-speed drivetrain and some other, similarly curious choices. Notable to this venue may be the cable routing and cable joint positioning: By using the "vertical dropout" anti-turn nuts, I have been able to run the shift cable up the seatstay. It is quite silly, but this setup is partly a proof-of-concept for a San-Jos8-on-the-cheap I hope to prep for cyclocross season. 25 pounds, more or less. Thanks especially to Dan Burkhart, who helped rather a lot with parts and technical support, though I was careful not to explain my ultimate plans to him, because I wanted him to have plausible deniability. He may want it. -- Ryan Cousineau http://www.wiredcola.com/ "In other newsgroups, they killfile trolls." "In rec.bicycles.racing, we coach them." |

Hey Ryan, congratulations on a cool build, and thanks for the plug. I'll be interested to know if you run into any problems with the cable crossing the chain like that given it's tight clearance. I'm sure cable removal and replacement will be easier than in the conventional position as looks like it is more accessable. Now get out and ride it.

Seriously, though--add the rapidfire shifter on a mild sweep bar and some Ritchey grips--and that'd be my ideal fast city bike--a lot like what I've ridden in the past, but lighter. I command you to get some blue bmx chainring bolts and lose the extra ring! The style gods will be pleased. BTW, I haven't messed with the Alfine yet, what's up with the plastic nonsense around the rear cog--my eyes first screamed, "PIE PLATE!" |

Dan Burkhart www.boomerbicycle.ca It looks like it is well clear of the chain. You can see it most clearly by looking at both of these photos: http://www.flickr.com/photos/rcousin...n/photostream/ http://www.flickr.com/photos/rcousin...n/photostream/ The chainline would have to be pretty far off before the chain could touch the cable joint at all. The cable itself is entirely protected. I rode it to work today (very short commute), and it's in desperate need of more beer-can shims to stop the bar from rotating. The plan is to drink more beer tonight in order to generate some shim stock. In retrospect, I think I would use the trigger shifter instead of the rotary shifter, but I will probably skip straight to trying the Travel Agent hack instead. There are a couple of rides I want to try this weekend. One is a TT, and the justification for the absurd 53x18 gearing. -- Ryan Cousineau http://www.wiredcola.com/ "In other newsgroups, they killfile trolls." "In rec.bicycles.racing, we coach them." |

I am opposed to triathlism. The only run/bike/swim event on my calendar is the cyclocross race at Fletcher's Farm*. Seriously, though--add the rapidfire shifter on a mild sweep bar and some Ritchey grips--and that'd be my ideal fast city bike--a lot like what I've ridden in the past, but lighter. A lot of the inspiration for this project was looking at city bikes of various forms, and wondering why they were all so heavy. This bike provides some physical insight (it is, after all, 25 pounds, not 20 pounds) but one can see how you could do the same bike with more modern parts and achieve something pretty interesting. I don't know if there's five easy pounds to take off of this bike, but there's probably a couple in going to a lighter frame, fork, and headset. Some carbon fibre extremism around the bars and a lighter wheelset might be good for a few hundred grams, too. I command you to get some blue bmx chainring bolts and lose the extra ring! The style gods will be pleased. I'll look for the blue bolts. The extra ring is a tricky question. The rings are 53/44, and I envision using the 53 for TTs and then pulling a bit of chain and changing to the 44 for city riding. BTW, I haven't messed with the Alfine yet, what's up with the plastic nonsense around the rear cog--my eyes first screamed, "PIE PLATE!" That's the plastic guard that is molded onto the Alfine cogs. You don't have to use that design: Shimano gearhubs will take any cog built to the Sturmey-Archer three-spline standard. I chose it because of its look and so I would never have to worry about losing my chain there. That is something that may be a legitimate issue once this bike morphs into its extra-silly mud-proof-cyclocross incarnation. PS: wait until you see the new fenders. *two years ago I did that event, which had a longish Le Mans-style start and a crossing through hub-deep water. It was wonderful. -- Ryan Cousineau http://www.wiredcola.com/ "In other newsgroups, they killfile trolls." "In rec.bicycles.racing, we coach them." |
