I just rebuilt it with new parts during my visit to Washington in September. Below is a list of the general upgrades, but check out the notes for parts details. New parts traded in on the bike: - tougher wheels, built by yours truly -handlebars and stems -rear derailleur -rack -saddles -lighting (schmidt nabendynamo + led lighting) -tires -fenders -brakes/levers -drum brake -cables and housing Rebuilding this bike proved interesting and challenging. Several components were odd sizes, and the tolerances of french aluminum parts from the 1980's just weren't so great. The seat posts are 26.4mm (ugh), the new Nitto stem needed a tiny bit of light sanding to slide into the fork neatly (wtf?), and the original stoker stem was just an embarrassing disaster that demanded replacement after it would barely slide over the seatpost (grrrr). After two days of tinkering and a visit to Aaron's Bike Repair in West Seattle (cool shop, but a very pretentious owner) to get some seat post and stem shims and some tires the tandem is rolling and ready for action. First ride report: Very smooth and comfortable. I put on the biggest tires I could fit under the fenders, and they were adequate for moderate stretches of rough gravel road and perfect on pavement. We had a small problem with the stoker stem/seat post configuration that was allowing the rear handlebars and stem to spin, but a little lock-tite seemed to calm the problem. The bike definitely needs the drum brake I installed in the rear (even on short hills it gets going pretty fast with lots of momentum). We rode it about 15 miles on its first outing and it was pretty much faultless. Lots of responsibility at the helm of a tandem though, so I have lots to learn before we go on a tour with this bike. sturmey-archer x-fd I was all set to build up a wheel last night when I found that spoke holes in sturmey-archer hub is rather large at almost 2.9mm. DT Competition spoke I was going to use is 2mm at elbow. Now I have to wait for DT spoke head washers and hope that would take care of it. Alternative was to use DT Alpine III spokes which are 2.3mm at elbow, but those are hard to get apparently, if at all, especially in the length I require for this build. bicycle front drum brake Sturmey-Archer S80 8-Speed hub includes shifter, cable, mounting hardware & 25t cog Hub Shell Material - 6061 Aluminum Axle Diameter - 13/32" Slotted Axle Length - 175.0mm Over Locknut Dimension - 127.0mm Spoke Holes - 36 Spoke Compatibility - 13g or 14g Sprocket Teeth - 23 or 25 tooth Weight - 1880g Overall Range - 325% Gear 1 - 100% (Direct Drive) Gear 2 - 130% Gear 3 - 148% Gear 4 - 169% Gear 5 - 192% Gear 6 - 220% Gear 7 - 250% Gear 8 - 325% Includes hub,twist shifter, cable, mounting hardware & 25t cog 305% gear range 25t cog Disc hub axle length is 185mm Freewheel axle length is 170mm Item Specifications ColorSilver Weight1600g Intended UseRoad Hub Drilling36spokes Rear Axle Type13/32" Cassette Body TypeSingle Cog Driver Hub/Brake Compatibility6-Bolt Disc Rear Hub Spacing127mm Skewer IncludedNA, Bolt-On Chainline39.8 See also: bike seat woman scott sub 20 bike boy on a bike tektro bike brakes swiss bike xo kids bicycle 20 bike commute to work bicycle pedal blocks |
