It looks like the biggest I can run is a 30 (depending on teh tire) 28 for sure. If tubed I’d run latex, not sure if that matters.
I like that Expanse. Looks perfect if it fits. The other ones i was looking at
- Bontrager AW2 TLR in a 28mm - Allows the tubeless setup to avoid the pinch flats in the gravel sections running lower pressure, but doesn’t look to be much sidewall grab at all.
- Bontrager R3 Clincher in a 28mm - Looks to be a good tread compromise to allow it to be fast on the flat paved sections and have some grab on the sides, but it’s tubed, so I’d be worried about pinch flats. a 28TLR would have been awesome, but looks like it’s not offered.
- Bontrager R4 clincher in a 28mm - Looks a lot like a Panaracer Gravel King to give an even greater grip, but again, is tubed. Pinch flat being the concern again.
- WTB expanse in 30mm
- Roubaix Pro 2Bliss Ready in a 25/28 or 30/32 (would need to measure).
I’m leaning towards #4 if I can fit it, with #5 being plan B and #2 or 3 being plan C. So many choices. Now I understand why @Nate_Pearson & @Jonathan spent so much time talking about tire choices in the podcast. It’s much easier on my TT bike!
