freegan bikefascist you're probably right, nl was specific about "equivalent priced". it's not realistic to compare alfine to top end 3×9 as there would be a huge price difference and therefore have completely different customer base.
as for unsprung weight i agree, there's no point having suspension then have loads of weight the wrong side of it. my point to glenh was that i'd doubt it would have much effect on the way the suspension operates, several hundred grams may have shifted to the rear wheel but this is nothing compared to the biggest moving mass on the bike i.e. the rider, who could weight anything from 50-110 kg (4-9 times the weight of the bike itself), that's a hell of a lot of range for a suspension system to cope with nevermind the fact that it's not fixed in one place.
personally i'm less concerned about the range, as long as i can gear 1st to match a 3×9 1st i'd be happy, it would mean i'm missing my 3 highest gears but i only ever use those on down hill road sections, though i think the gaps are slightly bigger on the 11 (not so keen on that) so i'd actually only lose my top 2 ratios.
anyway, only 6 months to wait, i need to get some bits together!
