I’ve got a minion dhf 2.5 wt on the front of my bike – the rim is a Dt Swiss e1900. Believe it has an 30mm outside diameter but only a 25mm internal diameter.
Had it on there a month or so, and so far it’s great. For the riding I do (hardpack trail center mostly – but very slippery when wet) it’s a big upgrade over the 2.3 dhr2 I had on there before. Both exo 3c and run tubeless.
Incidentally the dhr2 is now on the back, replacing an aggressor for the winter. The aggressor was great for the summer but doesn’t have good drive forward if it encounters any mud. I’d say the dhr2 is much better for straight line traction, but in the corners on hardpack I’d say it’s a bit looser. Much prefer it on the back to the front.
