Hardest tyre/rim combo I’ve ever tried to set up tubeless: tried them dry, rubbed with Stans, soapy water, re-seated using a tube and so on. I got so frustrated I went out and bought the £80 compressor from Aldi (I wanted one anyway), and I’m not sure I’d have popped it without.
Couple of points for those that haven’t done the conversion yet:
1. My rims were already taped, thanks Trek 🙂
2. You need tubeless valves with threads right to the bottom of the valve
3. I tried Stans valves, but couldn’t get them tight enough. Bought some Specialized Royal valves which have a square base inside the rim and easy to grip while you tighten the valve nut and they are only £3 each)
4. They are on now, but four scoops of Stans in each and they are still leaking from the bead. More Stans, and a few more pedals around the doors should hopefully do it
5. The tubes are seriously heavy, I reckon I’ve lost 2lb off the bike. Maybe.
6. Those Aldi compressors, in a small garage, are **** noisy
