SON Archetype w/ Shutter Precision dynamo… very nice!
I’ve just finished putting the last touches on my new audax wheelset, which I hope will be seeing some heavy action in 2013.
Based around the SON Archetype rim, Shutter Precision SP8 dynamo and a Novatec lightweight rear hub, laced 32h 3-cross with Sapim Lasers, the total weight for the finished wheels is just 1930g. Not bad when you consider it’s saving me around 300g of LiPo batteries on the longer rides… effectively a 1630g wheelset!
I should probably also offset the substantial cost of new batteries I won’t be buying against the cost of the parts (totalling £300.77). I sourced the hubs separately, but got rims and spokes from DCR Wheels in the UK, a pleasure to deal with 🙂
As my previous Raptobike wheelset weighed 2.1kg, I’ve cut half a kilo from my overall bike weight without dropping spoke count or compromising durability. (The strange black anodising over the machined brake tracks will quickly wear off, alas…)
The SP dynamo in particular is incredibly tiny. It’s hard to believe that it outputs the full power of a SON or Shimano dynamo in such a small and lightweight format… it barely looks like anything more than a slightly old-school front hub at first glance.
Incidentally, I won’t be using my Strava bike to ride brevets! This is just to allow me to bounce off a few kerbs and iron out any kinks in the lacing. In reality they’ll be going on a new MetaBike or High Baron (tbc – but looking very much like the latter).
I’m also quite excited by these new 28mm Ultremo ZX tyres. Fitted to the wide Archetype rims these measure 29.6mm actual, which is not so much less than my comfortable Kojaks (32mm actual). However when you handle both tyres the much thinner, more supple casing and tread of the Ultremo jumps out at you. I expect and hope these will be real mile-eaters over the coming season.
As they were on half price from Planet X I just bought four tyres, settling any worry about durability for this audax season at least! 🙂
Notes on weight
The Archetypes came in right on the mark at 450g. The spokes/nipples worked out at 185g per wheel (just over 100g penalty compared with a courageous 20/24 lacing).
The Novatec hub weighs 275g and the SP SV8 386g.
