This question is for Tom D. or anyone else in the bike business and concerns 9-speed titanium cassettes that are produced by a company named Cycle Dynamics (http://www.cycle-dynamics.com/index.html). Although this product can be bought in a few shops around the US, they also market direct and I am considering purchasing a 9-spd 11-19 straight block cassette for my TT-bike. The price is reasonable - about $120 plus shipping for a 110-gram cassette - but I was wondering if anyone has any experience with this companies products?
We purchased cassettes from them a few years ago for Campy 9 speed applications on a shimano freehub. They had a cassette that fit the shimano spline but was spaced out for campy 9. The last two cogs interlocked and had an extra long lock nut to hold the whole thing together. They were very nicely made unfortunately for us campy switched to 10 speed right after we received our first shipment. I have a bunch still in stock. 12-21, 12-23, 12-25. All titanium. I would sell them cheap if anyone is running campy 9 and wants to use it on a shimano wheel or the individual cogs are shimano splined. The only two that would be unusable would be the last two (12-13 )because of the unique interlocking setup. All the other cogs could be used as normal shimano cogs. You would just have to get Shimano spacers. I am using a 12-25 on my cyclocross bike right now.
