    upgrade

    2.0 spec Hi Stuart, It's hard for us to support upgrades like this directly with parts, because we have to buy everything in lots of 100. When I built the Quest 2.0 prototype using a Quest 1.0 as the base, the DualDrive Hub kit was $476 including shifter and clickbox, the rim had to...

    Setting knee clearance and x-seam on the silvio 1.5

    There seems to be some confusion around independently setting the knee clearance/handlebar position and the bottom bracket position/x-seam length on the Silvio 1.5. I've placed a short blog entry showing how to do this. http://cruzbike.com/setting-knee-clearance-and-x-seam-silvio-15...

    3 speed hub

    The internal The internal 3-speed-with-cassette solves the issue of changing chainstay angle as the adjustable front tube (AFT) is moved to accommodate different x-seams. Front derailleurs tend to drag the chain for riders with very short x-seams, which required us to offer an offset front...

    Checking In

    Good to hear from you. I hear you on the work situation... haven't been on a bike in embarassingly long. Lots of new stuff in the pipeline, though. Should be an interesting spring/summer. Gas'll hit $5/gallon about the time the weather is good enough for commuting... Cheers, Doug

    Cruztrike

    Hi Jim, Actually the team has been chatting about this quite a bit lately. Several of our designs would lend themselves to a performance trike conversion, even a tilting design if we could come up with something light and effective. We have several major initiatives to complete in the short...

    Crank arm bolt torque?

    Hi Trev, See here: http://www.cncexpo.com/MetricBoltTorque.aspx Use specs for 8.8 - 8mm bolt; you can lube it or not as you like (I like a bit of light oil on a properly-torqued bolt). Note these numbers are in inch-lbs. Cheers, Doug

    IGH and Quest 559 don't mix, is that right(?)

    Hi Toby, I don't remember which parts you've replaced - is your derailleur hanger straight? John and I had a discussion about chain slippage a few nights back. If you run the b-tension screw all the way in, it increases the chain tension, but at the expense of "chain wrap" around the cassette...

    Cruzbike for touring?

    Hi Sean, Three of our bikes are well-suited to loaded touring: Sofrider Quest Sigma All three use robust aluminum frames and have ample mounting points for racks. The Sofrider and Quest will accept MTB seatpost racks, and can carry underseat loads with a little ingenuity. David Byrne is...

    Shorten my chain?

    Lemme understand, the chain drops off the front chainring when you shift the rear derailleur up? Is this an 8 or 16sp? Best, Doug

    Cannondale super V 900 as a Cruzbike?

    Hi, The seat height can actually work out pretty well on this frame, but the stem compatibility will probably be an issue. I think Jack (Defjack) has dealt with this before, but as I remember it was a challenge. Good luck, on whichever approach you take - we'll all be around to help. Best, Doug

    One week review

    Great ride summary - 300m with no hands already - very impressive. I'm taking my Q559 to the Outer Banks of NC next week. 45 miles of off-highway bike paths. Hoping the weather is good. I've noticed some folks like to have a little more lumbar on the seat. You can place a piece of exercise mat...

    Which chain?

    Hi Trev, Hard to go wrong with SRAM chains. A good alternative is KMC. Generally inexpensive, but smooth-running. I've used SRAM, KMC and Shimano, when it was on sale at the LBS. SRAM and KMC are neck-and-neck; Shimnao is usually expensive for no better quality. We use YBN chains on some of...

    How wide a TIRE can I run safely?

    Generally about 2 inches is as wide as will dependably clear the front fork legs and front chainstays for 26" tires. Remember that the rim width will affect the ultimate width of the tire sidewall-to-sidewall. Best, Doug

    Seat Post Clamp-on Rear Rack for Sofrider

    Hi Rome, I use a Topeak MTX - A type rack on my Vk2. It has 700 x 38c tires and I have no clearance problems. http://www.rei.com/product/697096 There are 3 types of MTX racks; the A-type is listed as "small". It mounts easier if you substitute a 40mm M6 bolt in place of the quick release...
