I have one Riv model, a 60cm Bombadil which I have setup as a road bike with 38mm tires and drop bars. I'm also 74+ inches tall and propotionately long inseam. While I love looking at model after model of many a bike brand, regardless of material or any other parameter, there are very few production models that offer a combination of frame dimensions that are accetable to me, as in they just aren't very long front-of-center. One of the few is a VO Rando road bike, a frame I bought a few years ago. Otherwise it's custom, in particular from Jack of Franklin Frames in Ohio. I have one from '99, and one soon to be. I'm also intrigued by their(VO) Chessie and Piolet frames. Variety !
I'm interested in frame designs, desiging them. I don't care about the branding on the side. A cow can be branded any which way but the cow is still the same cow :-) It doesn't become any more or less than it already is. I'll look at any frames geometry, regardless of the material. I'm mostly checking out the variety of gravel based frames, and sure enough it varies wildly. I'm not sure if I could ever get carbon or alloy frame designed for intergrated everything, brifters and the like, but I can use the geometry and make a steel frame with such qualities. I'm designing one right now and I'm contemplating a front end of a 71-71.5d HTA, with a upper 50's to low 60's trail, and 17-20mm, of wheel flop. The steering, the combo of HTA, rake and tire size is what gives a bike a "stable" feeling, not BB drop alone. The trail and wheel flop along with the BB drop, and really the entire design. I could have 80mm of drop with a very low trail front end and it would never be considered "stable", hah hah ! Grocery carts are very low to the ground, with no trail, and anything but stable ! My Bomba for example has about 70mm of BB drop(measured by me) with a 20mm-ish of wheel flop and low 60's trail and exhibits the "stability" Rivendell is known for. I'd call it more "predicatable" or "intuitive" as the desinger/Grant has defined and designed it to be. One way of the many !
