I have GT Grade set up as a road bike with 28mm Conti 42ksii tires and have the weight down to just a bit above 19lbs. IMO, it works great, though I'm a solo rec rider FWIW.
Factually speaking what are the real differences once the wheelset is swapped?
- stack and reach: can you get low enough for the road? I went with a slammed -17 deg stem to get low. I'm not tall but if you are, you might be fine just removing spacers and flipping the stem.
- wheelbase, headtube angle, trail: does the handling feel sluggish to you once you've test ridden it? Subjective.
- handle bars: the wide flared bars sucked on the road. I went with a narrower bar for more comfort and more aero.
- gearing: 46x11 is good enough to spin out at 40mph IIRC. Mine is 50-12, which is the same top gear as 46-11 last time I checked.
