What a collection you've got, class man chapeau. I can't even say which one I like best, they're all that nice. I have the same wheelset build coming up as your nemesis + record hubs. What's the length of those dt spokes you're using btw?
Nemesis rims 32hole and Record hubs (black) with DT Competition spokes I've built several sets with the following spoke lengths:
Front wheel: 302mm
Rear wheel DS: 299mm
Rear wheel NDS: 302mm (301 would have been ideal but 302's worked just fine and I didn't have to have a third length for the build)
On one build I experimented with DT Revolutions on the rear NDS. I thought they might stretch a bit more and went with 300mm length because of that and any lengths longer than that were difficult to get at the time. The 300's are fine, 301's would be perfect and 302's would work too.
Glad you're enjoying your bike. If I were to go sloping that would be the size I'd go for, 56s. What is your saddle height as shown in your pic? Just curious. Looks like it would be higher than say 81cm which must give you a pretty aggressive drop to the tops of the bars it looks like.
Thanks for the info on the spokes Calnago, damn I have 64 DT comp spokes and they're all around 295mm, I am guessing that would be on the shorter side of things. Saddle height as shown in pic is 82cm and my drop is 11.5 cm (measured at the hoods), stem is basically slammed. I do like a bit of drop, for reference I am 192 cm with a 92.5 cm inseam.
