Well, it had to happen eventually – we had a rather small turnout of attendees (about a dozen) and of show-and-tell items, but this is a group that can be counted on to fill the available meeting time with something even so. And we did! Tim Dunsworth passed around some photos from the recent Stevens Point Recumbent Rally, including a number of unique homebuilts you will be able to read more about in the August meeting notes (or will have already read about by the time this write-up comes out – it's tricky writing with a publication lag in mind).
Web Space Fund Drive
Mark reported that when he had requested donations to register a 2nd MnHPVA domain with to get more web space, (for meeting write-ups, event pictures, etc.) the first five checks totalled $150 when he only needed $90. He said he could either take Jane out to a nice dinner with the extra, or try to collect another $30 so that he wouldn't have to go back into Pledge Week mode again when it's again when it's time to renew the original domain in April '06. The fund drive lasted all of about 3 minutes, since a half dozen people immediately stepped up and exceeded his $30 target with $50 of donations.

At this point Carl mentioned that he had had Dave register a domain for Edina Bike through and cited a referral from MnHPVA. So, we got the 100 Mb bonus without needing the 2nd domain. With the extra 100 Mb we should be flush with capacity for some time to come, since the monthly meeting write-ups take very little space for HTML code and he keeps most pictures small for faster down-loading to members who don't have broadband connections. Mark will give Dave all the money, so that when it's time for him to renew he can also then get the 2nd domain which will bring us up to 240 MB.

Even after all of this, people have insisted on donating still more, saying "Use it for the ice races or something." Mark

Mark reminded us that Sunday the 19th will be the annual ABCE (All British Cycle Event) ride and get-together. Mark is going to be riding a really sweet (if he does say so himself) 1958 Jack Taylor that he built up from a frame, using a variety of swapped or donated parts.

Dave Siskind provided a nice set of hammered aluminum fenders from his 1963 Taylor tandem. And a Campy Nuevo Record rear derailleur from the 60's, with over seventeen thousand miles on it. Mark passed it around to show that after removing some crud it still looks brand new.

While mere mortals like us would have dinged it up just mounting it and removing it once, Dave had managed to put 17,732 miles on it without a scratch. Mark knows the exact milage, because in his latest book Dave lists the miles he's gotten out of every component, even tires and chains, in his 420,000+ miles on a bike.

There was a good turnout, 35 or so, which included 3 guys from Missouri and at least 7 MnHPVA members. Weather was perfect, and apparently I'm not the only one who thinks the Taylor looks sweet, as it won the "Peoples Choice" voting. Not that it was the "Best" bike there. It's not very original and would have been lucky to get in the top 5 with formal judging. But it sure is great eye candy. Mark

Crank Length and Power Output
We had some more discussion between Mark and Carl about regular vs short cranks and general bicycle biomechanical issues. One point Mark thought of after our previous discussion of this issue is that the way people rock a wedgie from side to side when climbing hard out of the saddle in effect makes it act like it had shorter cranks, supporting his point that the expected loss of leverage from short cranks is made up to some degree by operating the leg muscles closer to full extension where they are most powerful (and least likely to over-strain the bent knees?).

Carl still believes that it is both possible and practical to generate higher forces on a recumbent because you can push against a seat back, though others thought that doing high intensity leg presses couldn't be sustained for long and would lead to blowing out your knees for most people.

Carl insisted that this could be sustained for a long time at a fraction of the maximum force (which would still be more than you could exert on a wedgie for a similar time), and that there are ways to mash without blowing out your knees. [I have long since moved to a spinning style and don't plan to go back, but there was a time when I would have pressed him for details on how to do that. I am frankly skeptical, though. Tim.]
