Not sure your numbers quite add up there njee. It's not like you stop dead when you shift so you won't be losing 2s per shift but there's certainly some time to be made.
It was a generalisation, but if you need to shift up the cassette when you're out of the saddle you can, if you need to drop to the granny you can't, I reckon it's not far off that. Either way, 2x9 better than 3x9 with road cassette.

26 and 38 middleburn rings, with an 11-32 on the back. Been getting huge amounts of chainsuck when shifting down, still haven't sorted it yet. And now that I don't have any forks I don't have much chance to, for now.
Perfect gearing though. Got me up nearly everything in the Alps (not enough skill for the other bits).
unabashed definately looks nicest
But defeats the real point of 2x9, which is being able to ride in your Chinos. 😉

Nah, real point of 2x9 is that it shows were clever enough not to fall for the whole "triple ring" scam. No one really needs a triple, but the bike manufacturers say you do, so people keep buying them. 😉
To be fair triples made sense when mtbs were 5 speed meaning that you'd need big jumps in sprockets to get any range with a double.
Next week: DIY adjustable rake suspension fork, a 6 hr conversion of some otherwise perfectly functional trail forks with some springs from a chesterfield sofa, a length of threaded bar, some bamboo garden canes and profuse nuts & bolts renders a working prototype. Postulated benefits include 'becuase I could' and 'gives me something to talk about' with the added 'baby sick avoidance' bonus.
Its lighter, not as much as a mud trap as a triple, more clearance, less stuff to replace from wear, cheaper, etc. etc.
Lol@ adh 🙂
A further further follow up.
I've replaced the XTR front mech with an [url= http://www.chainreactioncycles.com/Models.aspx?ModelID=27692 ]SLX double-specific[/url] one and it now runs perfectly - no chain drops, shifts spot on and all gears are useable in both chainrings. Really chuffed with it.
