hmm, that might also result hmm, that might also result in a different sort of chain wear since the rollers would be reversing direction each time they go around the chainwheel and cluster. might be good, or bad or more likely, no difference. I have never ridden a back to back tandem, but...

i prefer the layout of the i prefer the layout of the back to back tandem by tom traylor (except have the stoker pedal backwards into a flipped over wheel rather than use his many idler layout which is used to allow the stoker to have a normal forward pedal stroke)...

how much power difference for the disc wheel? Hi Jim, Since you are using a power meter, have you investigated how much less drag (or at least the power difference at some "test speed" )the rear disc wheel is giving compared to a spoked wheel (and how many spokes?) at some defined speed...

I guess the sculpting is fun. I guess the sculpting is fun. would love to have a go at it too but I can't get suitable foam here in small town NZ (and then there is the question of how much time could be allotted to it after work and domestic duties (and sleep!). Keep the pictures coming!

Interestingly the video Interestingly the video doesn't contain any "doorings" (also a feature of biking in melbourne in the non-separated "bike lanes" painted on so many of the streets.) But many memories watching it, so many routes just work naturally with a bike in the city.

Price drop New price is 450 NZ Dollars ($US375) including the fairing. 330 NZD ($US 275) without the fairing.

Eric, the hard shell does Eric, the hard shell does allow for internal padding and abrasion protection though, at a cost of perhaps more frontal area . Looks awesome Jim!

How are you shaping the foam? How are you shaping the foam? Just sanding or a coarse rasp?

Looks great. The dip in the Looks great. The dip in the middle skill also mean a nice short, (simple?) connection between the fairing and the top of the boom. could be interesting to see if there would be much drag difference between this double hump shape add a more typical "torpedo" shape...

Price drop New price 500 NZ dollars with the fairing, 380 NZ Dollars without.

Looks like you'll have a good Looks like you'll have a good view through there once the shaping is done. The vector tricycles had a very laid back postition and had big clear canopy for forward vision, but I read that they were terribly prone to solar heating and/or fogging. your concept...

Interesting that your Interesting that your templates seem to show a central dip with the pedal/toe clearance humps either side. Is your choice of this for better forward vision? Hope it works out well. I think the moving bottom bracket format makes for really simple and solid...

front half fairing or both front half fairing or both front and back with a lycra joint? Composite or moulded zotefoam?

My vendetta is set up the way I like it and I'm used to it now, and I'm not commuting 23km each way (rain or shine - love the fairing even if it gets odd looks!) any more, so I don't need this conversion bike any more and it's for sale. Located in Nelson, New Zealand. With the big windwrap...

Note, I fitted the seat Note, I fitted the seat bracket to the top tube with drilled and tapped M6 holes, not the awful looking original cruzbike kit solution of two big radiator hose clamps (hence why they are not there!).

My newly acquired Vendetta 1.5 is to be my daily driver to work (23km), and if I am to fully replace the heavy conversion, I need fenders to deal with the wet days. With fenders and a fairing, my heavy cruz conversion is great even in a downpour! I found that the SKS raceblade long fenders...

Just measured the clearances Just measured the clearances on my Vendetta 1.5. I'll leave it to JT to confirm any differences to the V2.0. Tightest is the front of the fork crown. Without removing the brake I cant get a caliper in there, looks tight might be 5mm or even less. I have 23mm...

My conversion frame is almost My conversion frame is almost identical (but i haven't yet cut off the BB.). I replaced the original shock (which was 150mm long) with a 100mm one (very cheap on Ebay, about 15 dollars including postage!). This lowers the seat, increases the front BB height...

A combined spring and shock A combined spring and shock absorber always absorbs energy whenever it moves. Although the spring returns all energy which it sites during compression, the shock absorber does not. If it didn't work that way, going over a bump would result in you continuing to bounce...
