1. I ride thin tires, 2.1 or 2.25.
A 2.35 could fit, but it depends on the rim width.
Do you know the width of the rim/tire combo you'd like to put?
2. Yes, the replacement arrived without any surprise or issues. The warranty from Peter is real.
It was a first batch problem it seems. After ~5000Km of hard rides, the replacement frame is still going strong.
I love this frame, it is the stiffest I tried( direct from China or some branded bikes ), and coupled with the Lauf fork, it is a bomb
If I would crash it today, I would probably order another one.
Just to temper. This can be very personal obviously.
For instance the wife of cmh who rides strong, tried one, and wasn't happy at all from the frame:
