People hung out in the parking lot for quite a while because it was a pleasant evening and because some of the interesting goodies to check out were to be seen only in the parking lot. A Pedalcoupe showed up again, allowing a few more people to see it and try it out. And Jim Black had a sociable tandem with two kinds of electric assist units to compare.

Chris Burbank's Aluminum SWB
Carl Gulbronson passed out red licorice whips as a treat (Thanks, Carl!), then showed off some miscellaneous goodies:
1. He had some Bebop pedals that are fairly light and cheap clones of the Speedplay pedals (and recently survived a legal challenge from them for design infringement).
2. Sun now makes a much cheaper clone of the mid-size ZZipper fairing using the thicker (0.060?) lexan material.

Jim Black's Electic Quadribent
David Eggleston drove up from Texas on Friday and Saturday of last week with two slightly different enclosed trikes on a trailer. He imports them as kits and will also assemble them for US customers. They are semi-monococque aluminum structures that are bent to shape from sheet stock with just one direction of curvature and then put together with LOTS of pop rivets. The compound curved nosecone is a molded plastic piece.

A number of people tried them out and liked them pretty well. Mary Arneson thought they were sportier than her Cab-bike but not as practical due to the open cockpit with no rain protection. They did a ride around the city lakes with more velomobiles than have probably ever been assembled in one place around here (and perhaps anywhere in the US), two Alleweders and three Cab-bikes. Pix and a report can be seen at

Mark Stonich's Sidecar Goodies
For small orders of steel tubing, a local branch (or franchise?) of Metal Supermarkets was recommended. It is located in Roseville at Fairview and Hiway 36. It is not as cheap, nor does it have as wide a range of stock as Dilsberg or Aircraft Spruce, but it is local and convenient, and for a small purchase the price may be offset by not having to pay shipping charges. See for more info. Denis Diekoff had another news update on the 29th Street Greenway. He was riding on it near the east end (the old Honeywell facility) and saw lots of dump trucks bringing in loads of trail base materials, so it looks like some real paving work should start soon.

Denis volunteered to bring some government bike guy (almost a contradiction in terms, but we can always hope!) he has been in touch with to a future meeting. This person has expressed a willingness to talk for a half hour or so on any topic we are interested in and he is knowledgeable on. Dennis will check to see what his actual job title is and what topics this might include. He will post more info on the listserv when he has it.
A tip from the Hostel Shoppe website on setting the proper chain length, which Mark thinks has about the best explanation he has seen. Wrap the chain around the big-big sprocket set without going through the rear derailleur at all, then cut it off so it has one or two links of overlap. Details here. Mark was going to do a chapter for the fifth edition of "Lord of the Chainrings" by Bill Patterson (an interesting mixture of mathematical models that may or may not be relevant to real world bike handling, plus some personal opinions), but when Bill made some unacceptable editing changes Mark just withdrew it completely. He will try to set up a web page to make this material widely available. He has some hope that Patterson is finally realizing that the earlier editions were not the exclusive or complete source of truth and wisdom on bike handling.
