To be honest I think that the weight thing is a little over done. I didn’t weigh my frame, just swapped the parts across from my 853 Inbred and the total build weight didn’t seem to differ much and I certainly can’t feel it when riding; that extra weight (if it is there just seems to vanish in the general mass that is my bike). The WMB test that the Sirius won against some stiff competition did laud it for those desireable steel qualities (and it even built up into the lightest bike on test if I remember rightly) so if it is a tad portly it doesn’t seem to have affected things ‘off the scales’.
Equally I do get that people don’t want their bikes heavier than they need be, but weight doesn’t necessarily equate to ‘bad’. I suspect that the Kinesis Decade Virsa is a lighter steel frame, but then there’s been talk about cracking seat tubes, I’m pretty certain that the Cove Handjob’s lighter but there have been issues with crumpled downtubes then again everyone seems to love the Orange P7 despite the fact that it makes the Sirius look seriously under-nourished. I suppose we could call the Sirius ‘robust’ (which to me is a good thing) rather than athletic.
The Sirius (and I suspect the Scion) isn’t a race whippet, but if that’s what you really want steel probably isn’t the best choice anyway. If I were buying now I’d probably choose the Scion over the Sirius as I don’t need the sliding dropouts, there are plenty of other contenders out there too. I really like my Sirius (and I tend only to pootle about on country roads and trails) and am really happy with what I’ve got.
As far as I can make out the Scion is identical to the Sirius except for the loss of the sliding dropouts and16mm as opposed to 19mm chainstays. I assume it’s CEN tested too.
pipedream themselves say just the sliding drop-outs weigh 300g
But the Scion will still have dropouts! They’ve had to replace ’em with something so you’re not going to lose anything like 300g.
I really like the ride from my R853 but not the weight.
I was pretty deflated after getting my Sirius when everyone went on about the weight but after spending a while getting it set up right, the more I ride it the more I like it. If it was lighter would it ride better? Perhaps but then again I like the fact it’s a little less ‘waggy’ than the 853 Inbred, a lighter frame might be more flexy. In any event for me it’s the ride that counts.
