Every time I go back to mine (05?) from the Ti29er, I remember why it's the weapon of choice at many of the trail centres and my longer distance adventures.
I was out on it last night and it makes my clumbsy riding look 1/2way competent. It never really feels quick (29ers always feel quick somehow), but timed sections tell otherwise, so did my ride mates last night once I'd waited for them !
It's an effortless ride and that's what makes it such a joy to be on – you'll start adding 1 or 2hrs to your routes once you have one & not be fatigued, I'm not sure how it does that TBH!
I've never read a bad word about them & they've got to one of the better looking bikes out there – I like the silver ones as above, in particular.
