Head tube angle, seat tube angle, bottom bracket drop from dropouts, chainstsy length, fork offset, and stack and reach.
All those measurements affect if a bike feels quick or slow, too big a reach or comfortable.
A basic top tube measurement really doesnt mean much at all for fit or style of ride.
These measurements are why some find a frame too twitchy while others like the same frame and find it quick handling and responsive.
Spending the money you are about to spend, i would think you would want to know how a frame will feel relative to a bike you know you like.
thanks for this, good advice.
I’ll get it measured up, and I’ll probably get a quick fit before I buy the frame too. I suppose my point is that I just don’t think I would know the difference between twitchy and quick handling/responsive because I haven’t had any long time with one size and style of road bike. So it’s really hard to know what will work. Suck it and see I suppose. I think I’d go for a 54, and then when it comes to fitting components, have a play with those sizes.
but yeah, it’s not gonna be cheap you’re right. And I would very much like to know that, but seems to be a hard thing for a rider like me to establish. I think thats a small reason why the Colnago just pipped it too- so many people like the ride and are happy with the sizing and comfort, so I can take some solace in that. Plus if there’s an issue, there will be others who can advise.
