These are done.
Went to the LBS (Monkey Wrench Canberra) to talk to buds about the wheel options and they came up with some very nice kit. Ended up getting the refuse 40mm from them, and some Hope pro 2 evo that are now “superseded” by the pro 4s. Paired them with DT revs, brass nips and WTB frequency i19 team rims.
The build went kind of OK, the rims started out way out of true, but came back quick enough. What shocked me was the flex in them at 100kpghrf when de-stressing them (axle on floor, weighting rim). I’ve not felt a rim flex like that before, even ZTR 355 and crest, DT RR415, nothing. The nipples were unseating very noticeably. Anyway, I kept tapping away at it and they were pretty decent when I called it a day, though I was skeptical of their stiffness.
Mounted the tyres today, with stans 22mm tape, sealant and valves was easy enough (tried initially to bluff my way through with blue tape… it was not good), sealed without suds and with a high pressure track pump, valve core in. Took them for a spin at 55psi front, 60 rear and man, they feel good! A nice zing to them, spin up very easily and definitely a noticeable step up in steering directness. The wheels have ended up plenty stiff.
Wheels came in at 1760g without tape or anything, tyres were 525g each. Mounted up, the 40mm refuse measured 38mm on the 18.5mm internal width rims. The tyres really look and feel good, will report if things go astray with em.
