Ok chaps...its not a prototype.Those pictures are from the official launch (At a Rock/Bike festival :wink:) prior to the main launch at Eurobike.
It will be available to order post Eurobike with either belt or chain drive, either is retrofittable to the other, as are box internals of 9, 12 or 18spd. That one is 12sp, which is 150g heavier than 9sp but closer ratio's.
It is forward geometry utilising the geometry developed with Chris (and others but I think that bike will be offered in Chris Ps long/longer/longest designation.
Of course you can go custom do what you want within reason...like a shorter seat tube springs to mind) over the last 18 months.
Allegedly, (since I haven't ridden this one yet, not until next week, but from discussion with those that designed it and have been testing it for quite some time) The pinion application particularly suits the geometry, the weight distribution further enhances the cornering due to the technique used with this type of geometry, as anyone who has ridden or has one will attest, you don't get over the front in corners in the same way as on a shorter, steeper bike, much like you don't lean back on the steeps, its much more centrally weighted.
With the right parts (e.g. those on my current, but going to a new home, überlong (Longest equiv) Ion16 squeeze

e.g. carbon wheels, Vecnum dropper, carbon bars, lighter brakes, lighter discs, lighter grips, lighter stem.. ) it comes in at 15kg or 33lb.
I understand the tensioner design/setup is there to manage belt tension dynamically, the objective to reduce the resistance to the suspension action as far as possible e.g. to try and replicate as close as possible a chain/derailleur free suspension action for more sensitivity.
With regards to the heavy bit, it is. But in terms of manoeuvring the bike, the weight is in the right place and there is hardly any unsprung weight, the rear belt sprocket is very light, its also running a single speed hub for a dishless build, it has also got a huge gear range.
In terms of extra effort to just pedal it, this might surprise you, it did me!
...for a 75kg man, pulling a 3000m climbing day (more than most of us are likely to do in a stint), at a steady 5mph for 2 hours solid on a mtb, in avg temps, with avg tyres, the difference in energy expended is 81Kcals.
As a bit of a weight weenie and experimentalist I was both inherently attracted to the advantages this bike offers and simultaneously horrified at a bike over 30lbs again...having said that, I think there are many, in fact I know there are having seen a 'how much does your bike weigh' thread on here that are utterly deluded about their bikes weight
Anyways ,I'll report back after I've seen for myself...If I love it, great, if not, I'll try not to convince myself I want it anyway and carry on with the tweaked custom version of mine....
