Cyclocross Geom
Looking at cyclocross frames as a potential change for my commuter. angles look weird, which I can understand, but the top tube lengths seem much shorter. I normally take a 58cm frame size with a 57+cm toptube, but the frames I have looked at seem to have 1+ cm shorter top tubes? iis that right, or should I be looking at a size up?

CX frames sizes are always slightly shorter than road and should also have a slightly lower top-tube (ball-clearance). 1cm is about rightRecipe: shave legs sparingly, rub in embrocation and drizzle with freshly squeezed baby oil.0

Top tube is shorter as aerodynamics are not important on a crosser. The more upright position lends itself to better handling over the inevitable rough stuff. Much easier to negotiate rather than being at full stretch. I have a 55cm tt road bike and a 53cm tt crosser the seat tube is much the same on both though.Rock 'n' Roule0

Bottom bracket on most CX frames is also a little higher for ground clearance, so always opt for shorter seatube. As said, toptubes are generally shorter too - a smaller frame helps with handling as you can move your weight around more - likewise, saddle to bar drop tends to be less too - head-down, ar$e-up doesn't help much on really slippery conditions - your bike handling skills are more important. Because they ride a little higher and with fatter tyres, they feel a little odd at first but you soon get used to it.Make mine an Italian, with Campagnolo on the side..0

Cool, thanks very much. So I'm guessing that I'd need my bars up higher as well then, i.e. Lots of spacers?"And the Lord said unto Cain, 'where is Abel thy brother?' And he said, 'I know not: I dropped him on the climb up to the motorway bridge'."
