- front fork hit the frame when you need to turn more than some degrees. Usually we do not need to turn so much while riding, but it can be annoying when need to place the bike in the car. Even can be dangerous if you need to avoid with "hard" turn some unexpected obstacles or strict u-turns
- the rear brake is absolutely awful, its brake power is tooooo weak. More than that cleaning the part is always quite tricky and you need some special tools for adjusting brake pad when wheel change is needed. I have cut a standard allen key for the work, but requires patience
- lock system for the seatpost is weird and the closing bolt has the extreme risk to touch or even puncture the internal frame
I'm not familiar with the issue of turning on TM02. I will say that the turning radius on a TM01 is horrible. I just learned to live with this "characteristic" of the bike. My riding buddies find it hilarious that I have to pick up my bike and turn it to get around the hairpin going up to G.W. Bridge (NYC people know what I'm talking about). At the end of the day, it's a TT bike so the primary concern is for this thing to go fast in a straight line. It's always gonna be a little bit like bambi on ice, compared to a road bike. I'm curious how other TT bikes with an external steerer do in the turning radius department. Eyeballing the new Scott Plasma, it doesn't look better than the TM01.
As for the rear brake adjustment, yeah, it really sucks. For that reason, I ended up getting a few sets of rims from the same rim width. I hate adjusting brakes on the TM01. However, the point I keep coming back to is, if you buy this bike, you already know it's not gonna be a one-bike-fits-all solution. The so-called super bikes almost all have a Integration vs Serviceability trade off. If you have the right expectation, then you won't be disappointed.
As for your last point, I wasn't aware of this issue and would really like to hear more. It's not clear to me which bolt is problematic?
