+1 on the LT 301. I probably single handedly made Long Teng Great Again (MLTGA) on this forum, because i bought 2 frames, in parallel w 2 Winow, and i recommend LT as much as i advise against winow.
But the point is, a bike that still looks aero with 38C clearance, the 301 is an obvious contender. Doesnt hurt that they're cheap either.
Ribble has launched a range of all rounder bikes that would qualify, but i dont know off the top of my head where to source OEM frames that are similar to these.
My LT268 is fast AF, when built to be an aero machine, it really is. The 301 is definitely not the same frame (the down tube looks like a chonky boy, especially), but in spirit it's the same frame, with bigger clearance. And the 301 is much more modern, lighter and so on.
How do you rate the performance of your LT268 frame with other models, at what level would you classify the frame?
