 Effect of lane position in a blind left turn Just trying to introduce a bit of tech into the discussion. Consider a worst-case scenario roadway; a dense forest immediately adjacent to the edge of the road so sightlines are blocked in curves. Let w = width of each lane R = radius of turn (at centerline of road) d = distance of driver from centerline of road... more » By Joe Riel  - 2:33am - 4 new of 4 messages

 Best Repair Book So, the kid is going off to college, and he's taking two bikes (road/ 29er), and I'm ashamed to say that he is not mechanically gifted and that I never taught him much about bike repair. I just quietly performed my duties as fleet mechanic. My only excuse is that he did not get really manic about riding until just recently.... more » By Jay Beattie  - May 21 - 3 new of 3 messages

 indexing slipping (force SRAM) I've been having problems with my rear derailleur system where the indexing seems to be slipping on its own. It's a SRAM force with a 10 cog cassette. That is, shifting becomes funky and I hear that sound when I shift. I often have to over-push the paddles to get onto a larger cog. Eventually I can't get onto the largest cog at all. (This in fact caused some consternation on one steep pitch!) Other gears might skip or the cog drops down to the next smaller one.... more » By yirgster  - May 19 - 8 new of 8 messages

 How many miles/kilometres do you get out of a chain? ... ... You paid for two Campy chains and got 10k km out of the pair? That's only about 11% better than I do. I got 4506km out of my last X8 KMC chain. There are guys on the Thorn netsite, where I hang out because of the good Rohloff info, who commute in all kinds of British weather and get 10K plus out of a chain, every time. I'm just about the hardest guy on chains there, especially considering my chain runs inside a completely enclosing case (Hebie Chainglider). If I use an open chain, a good one lasts 2200km and a cheap SRAM is lucky to see a thousand miles/1600km.... more » By Andre Jute  - May 14 - 43 new of 43 messages

 Advice on bike to get ... If you can afford a little over a thousand dollars, the steel framed Surly Long Haul Trucker is a very sturdy touring bike, and my 58 cm has a really long head tube and allows a lot of handlebar height adjustment as you get your form back and can tuck down more. Oh... I see you balked at \$700. Never mind. But I *know* these guys... more » By Dan O  - May 13 - 26 new of 26 messages

 Garmin Edge 305 My Garmin Edge appears to have died. Yesterday I downloaded a ride and left it connected to my computer to charge. When It said charging complete I removed it but it failed to come on. Also it won't communicate with the computer. The computer behaves as if nothing is there. I suspect the lithium ion battery died. Is this a reasonable?... more » By steve  - May 13 - 5 new of 5 messages
