There is a round super spoke and the cx super spoke. Oddly enough i know sapims range.http://www.sapim.be/spokes/butted/super-spokes
Sapim dont list the cx super spoke on there website.
News to me, Malcolm, thanks for clearing that up. The spoke I'm thinking of is this one: http://www.starbike.com/en/sapim-super- ... ull-black/
If you have the enve 45's you already have climbing wheels. What you want now is something less stiff in order to climb better. It does not work that way the weight saving is not going to be big enough.
Well, this is Weight Weenies... My 45s on CK are 1200g. So there's a potential 425g saving on the wheels, with another 120g to come from switching from Conti Competitions to Veloflex Records (which I grant you I could do on the 45s). A bit more saving if I glue rather than tape - did you know that one wheel's worth of Jantex 14 is 30g? I think 585g (assuming 10g of glue per wheel) of weight saving will be noticeable; that's almost 10% of the current weight of the bike (and a whole 0.6% of the total system weight - I'm an idiot, but not a moron
What's disappointing me is that I have a set of DT Swiss RRC425/525Rs. They're supposed to weigh in at 950g. In fact they're 1100g. Now, I did replace the freehub with an 11sp one when I picked them up, and maybe the original was some kind of super-lightweight special item (in which case I'm once more an idiot for having moved the original on using BR for £25) but 150g seems like a big difference (in idiot-land). I might take one apart and see what the rims weigh, to see if a rebuild with Extralite hubs and Super-CXs would make the difference.
I'll keep an eye out for Reynolds KOMs, but if I'm picking up used wheels I might as well use the Enve 25s. The brake track will presumably be similar to my 45s - which is to say fine in the dry, nerve-wracking in the wet - but I'll use R-SYS SLRs in the wet, so I'm not that bothered on that score.
Extralite make bold claims for stiffness in their wheelset, citing high spoke tension. However my understanding is that stiffness (lateral, anyway) is a product of bracing angle and inherent rim stiffness, not spoke tension.
