I have four Schmolke-rimmed wheelsets:
1 x rim-brake shallow tubular (road)
1 x rim-brake 45mm clincher (road)
2 x disc-brake 45mm clincher (road and CX)
They're daily wheels and have held true throughout.
I've traditionally ridden tubulars on the road, CX and track, and the clincher 45mm Schmolkes with Veloflex and Ultradynamico tires feel just as good as the tubulars.
