I’m not sure where all this ‘correcting the mistakes …’, bodged CEN compliance and seriously overweight comes from. I didn’t weigh my frame (19.5″) but the overall build weight didn’t seem much different to my 853 Inbred build (the kit was transfered across), it certainly doesn’t feel any heavier to ride or, for that matter, slower or less comfty. In the WMB grouptest, which the Sirius won it was also the lighest build; I appreciate that magazine articles are hardly definitive but the bikes were given a serious test by competent individuals and they certainly didn’t seem to complain.
CEN compliance was a suprise, when I pre-ordered my frame in December the Sirius wasn’t going to be CEN tested, the frame that arrived many months later (after some long delays, the original ETA was December) the frame had been CEN tested and was, no doubt, a bit heavier as a result; I’m no expert but I can’t see, or more to the point, feel when riding, anything that suggests that it’s a bodge (nor in fact did the WTM team),the ride seems just as nice as my non-CEN 853 Inbred. My main gripe was the Pipedream didn’t inform me of the changes that were being made after my pre-order had be placed.
If I was buying again I’d probably go for the Scion, I don’t need sliding dropout and a little less weight in a frame that’s not going to be running 130mm fork and getting thrashed is probably a good thing and narrower chainstays might at a bit extra compliance (although the Sirius is a very comfy ride), but I’m really pleased with my Sirius.
