Sympathetic geometry

    Hey guys, unfortunately back problems are developing and the culprit is my road bike frame. It's too big. Anyway, now I'm after a bike or a frame with a sympathetic geometry. Components don't matter as I'll be putting my own on. I don't want to spend big. Was thinking of a Spesh Secteur and took one for a ride today and it's very comfy. The thing is I'd have to buy the whole bike to get the frame. Is there any way I can get a frame that meets my needs without having to buy a whole bike? AFAIK the secteur is one of the least aggressive geometries available.

    Size? Budget?

    The Secteur I was looking at was a compact geometry 58. Budget about €600 but I'd much prefer to spend €3-400 on a frame. Aluminium frame and carbon forks will be fine.

    Are you sure you can't change your position sufficiently by shortening stem and pointing it up?

    Yeah, I've done all I can. Got fitted and everything. New shorter stem the whole lot. No joy. I am not taking this decision lightly. Sucks balls to be honest!

    What is wrong with your current position that a new frame would fix?

    The bike's too big. No matter how I refine the position I can't change that fact. Top tube is too long and I'm too stretched on the bike. A smaller frame could do a lot to remedy this.

    OK. I've got a 50mm stem you can have for not much if you want to experiment with a shorter length.

    The problem with a smaller frame is that you'll tend to have more drop due to the shorter head tube, though I understand you're going for a relaxed geometry to fix this.

    Hmmm...interesting proposition Lumen and I appreciate the offer. If I were to go for a very short stem as you suggest I may lose out on height at the handlebars thus accentuating my flexibility and back problem. I've already upturned my existing shortened stem. The Secteur has the same geometry as the Roubaix and has a tall head tube to compensate for a shorter frame. That's what attracts me to it and I was wondering if there are any comparable alternatives in my original post. I'd like to try the short stem though as it could save me a lot of cash if it works out.

    You can get stems with a crazy amount of rise, I would try one of those (or indeed an adjustable one) before deciding you need a new bike.

    You can have the stem for €30. That's what I paid for it here, it's never been used (other than during my bike fitting when I put it on, found it was too short, and took it off again).

    The only thing worse than buying a wrong sized road bike is selling it and buying another wrong sized road bike.

    FWIW I have suffered much with my back, and the only thing that has helped has been off-the-bike exercise, running and swimming. Being very stretched out tends to help more than harm, in my own experience (yours may differ, obviously).
