Habanero Ti road w/ Dura Ace, Habanero Ti Cross w/ Dura Ace, MTB w Deore XT
Not racing but road (mostly) and trail riding. In short, I wish I had bought one earlier!
I bought a Habby cross frame based on 10k+ happy miles on my Habby road frame. I basically wanted something more versatile. I did have Mark do a semi-custom and route the cables road-style and extend the head tube about 1/2" to get the bars further up. Now, for every 1k miles I put on the cross frame, the road frame gets maybe 50 miles. In fact, it may be time to sell the road bike. The frame looks brand new while the Dura Ace parts are, well, aged.
The cross frame is more comfortable and more stable on the road. I run Dura Ace with a triple with several different wheelsets/tires ranging from Easton Circuits with Pro Race tires for centuries to Dura Ace hubs with 32hole 3x OpenPro rims with (IRC?) 35c cross tires.
One warning: Avoid Ritchey forks! I had severe front brake shudder with the original WCS fork. I tried everything: different pads, toe settings, different cantis, Vs with Travel Agents, mini-Vs, and more. I finally replaced the fork with an Alpha-Q CX and IRD Cafam cantis (like the Paul Touring but 1/2 the cost) and no more brake problems - they work almost as well as my Dura Ace brakes now.
BTW, kudos to Mark for all the support with the brake issues!
