Size L Trinity Pro TT with 165’s and no issues.
At low speeds tilt the frame towards the ground body more upright. Outer foot low inner high. No pedaling.
A TT or triathlon will only ever have a u turn done like that.
If this is a parking lot or gates on a multi use path, walk the bike. It isn’t designed to go 2 mph.
Either way….Scandi flick that sucker around tight corners.
Also gotta learn to bunny hop while in the extensions. You’ll forget a speed bump or pot hole one day and regret not knowing.
