yeah that's what Madcow suggested above. I ended up using the SL (j-bend) version and built them up to 110kgf DS,m. I think from memory this resulted in something like 60-65 NDS. Ive only done about 2000km on them but so far i havent taken it easy on the wheels yet they've been faultless. Still early days but i'm really impressed with these hubs and looking forward to racing on them next year!
I think i lied in my previous post. I just check my spoke tensions with my Park Tools TM-1. I have DT Aerolites on the drive side and lighter Sapim Super Spokes Non Drive side (j-bend hubs, not straight pull). With this combo i get (very consistent
readings of just under 13 (over 12.5) DS and 4.5 NDS. The Super spokes have a bladed section og 2.0x0.9mm and the Park Tools conversion chart doesn't have a conversion for such a spoke. The closest the chart offers is for a 2.0x0.8 spoke and a reading of 4.5=59.5kgf for that spoke, so i guess my reading of 4.5 on the slightly larger Super Spoke would equate to a tension of just over 50-53kgf or so. my DS tension atm equates to about 105kgf. So the ratio is around 47% which is pretty close to the calculated tension ratio for these hubs based of the geometry on paper no?
I think i only went for the SP version because of cost (spokes and hubs cost more) and because i wanted to experiment with the lighter spokes front and NDS on the rear. Im perfectly happy with these wheels and really cant fault them (1098g, they feel great and haven't exploded yet!) but i think id get the straight pulls next time just to get higher tensions for piece of mind and because they look cool. I do sometimes wonder if the wheels would feel even better/stiffer if id used Aerolites/Cx Rays on the front. But its no biggie for me the way they are now.
