General: 'Mirage' Cheapy Lo Pro Advice

Morning Folks
Anybody know anything about Mirage frames? I'm fairly sure by its white, neon yellow and orange it's 80s, very light Columbus tubing...Anyway, I was using this as my conversion pub bike for the last year or so and feel like a change and since I can't afford an Affinity I was wondering about slapping on a 650 fork and wheel to lower the front end. Has anyone done this or is this completely ridiculous? I'd continue riding as is if not, it's just that the frame is a Gee hair too tall so it smacks my balls from time to time. Thanks in advance

Sorry, meant to say it's just a standard road frame with the usual angle top tube as opposed to an angled one on lo pro's

Yeah, if you're smacking your balls on the frame, you should definitely get a frame which fits you.

Your idea of using a smaller wheel to lower your top tube is... Well, it's sketchy. A 650c fork/wheel will lower your front end about 5cm (this is obviously an estimation, please treat it as such). While that is not much, it may lower your standover height enough to accommodate your testicles. May. Keep in mind that it will only lower your measured standover by 2.5cm. Probably not enough. What this change will do for sure is completely change how the bike turns and feels on the road. The smaller wheel will absorb less road bump and noise, thus your ride will be more harsh. So you'll feel the bumps and potholes much more than before. The geometry change will also give you a much twitchier, tighter steering.

All in all, you're going to spend as much for this new fork and wheel as you would just buying a smaller road frame. Maybe less, but you'll have to deal with new issues such a change would bring.

BTW: A Lo Pro is a standard track frame with 700c wheels, the only difference is that it has a sloping top tube. The geometry corrects for this. It's not a pursuit bike and not designed for a front 650c. That doesn't mean that you can't use one, just that it isn't the intended wheel.
