    One-piece speed and cadence sensor unit on Vendetta?

    I have an old powertap hub I have an old powertap hub which can measure both speed and cadence at the hub itself, presumably cadence is detected by measuring the frequency of thetorque peaks felt by the hub. Not quite as accurate as a cadence sensor but less extra gear on board. If using a...

    Ugly but effective, with fairing for rain and (i hope) aero!

    4000 commuting on a cruzbike conversion Just ticked over the 4000th km on my cruzbike conversion today. Almost entirely it has seen daily 46km commuter duty, except for two sessions of Chung method aero testing on weekends. Good things: -the windwrap gx fairing and fenders makes rainy day...

    Rigidity of donor bike

    Looks like the headset is a Looks like the headset is a threaded 1", so you would need a 1" threaded to 1 1/8 converter, (about $10-15 on ebay). That's assuming that the original folding steerer is removable. Downside is that with a cruzbike you won't be able to fold the handlebars down...

    Ugly but effective, with fairing for rain and (i hope) aero!

    I'm looking over the top. I'm looking over the top. It's hard to say whether it would be more aero to look through, as that would increase the frontal area a bit ( the fairing is of course much wider than my head, about same as shoulders. Anyway, looking through it would be no good...

    Ugly but effective, with fairing for rain and (i hope) aero!

    That is part of the plan. I'm That is part of the plan. I'm turning over ideas on the best way to configure it. I don't like the socks which are open all the way along the bottom.I'm thinking of enclosing everything aft from the down tube plus rear disc cover, then front sock over the front...

    Ugly but effective, with fairing for rain and (i hope) aero!

    My conversion has gotten heavier - I added a fairing. But the fairing is GREAT for keeping more than half of me dry in wet weather, even really pouring rain my legs only get a little damp. No noise, the mountings I made are working great. Crosswinds are no problem. I can feel a little tugging...

    Amateur aerodynamics

    From reading on the Mosquito From reading on the Mosquito site, it seems to me that the diagonal strips are actually carbon, but most other stuff on the machine is wood, with a little aluminium here and there, and the two big carbon struts in the rear suspension. Looks like a really nice...

    Amateur aerodynamics

    the sides are probably the sides are probably compressing because you have a big detached flow eddy on both sides. Perhaps the nose is too bluff. With a more pointy shape you might be able to bring the separation point further aft. If the flow is not separated, the sides will suck outwards due...

    Sofrider or Conversion?

    Given that the only component Given that the only component differences for a softrider to a conversion really are that the rear (old front) axle is usually solid not quick release, and that the front fork of a softrider doesn't use the steel brackets and hoseclamps (I guess perhaps at most 500...

    Sofrider or Conversion?

    I did a "cheap" conversion, I did a "cheap" conversion, using a donor which I bought second hand for $100 (new zealand) - and at that it was even overpriced. But I used nice (very old shimano XTR) components and wheels from an unused mountain bike i had sitting around. Although the...

    the conversion kit's tft the conversion kit's tft adjustability really is a great and key feature. i moved my seat back a bit today in order to shorten the tft and thereby raise the bottom bracket some more. the daily 46 km round trip commute is a pleasure even though my conversion is very...

    A 1988 Moving Bottom Bracket front Wheel drive

    I saw this picture in an old issue (volume 9 no. 2) of the journal of Human Power (IHPVA).Check out that front chainring! I guess the front tube isn't telescoping. If it was, wouldn't that be prior art to the Cruzbike patents? In some ways I like the simple frame design. Not sure if there...
