    Around the handlebar where the shifter is.

    Yeah but you have 100% more gear range than Eagle with the same amount of gear intervals. You get a larger shift per gear step, and be honest, how often do you find yourself on a gradient reversal that requires massive drops of gears? It's more of a problem for if you're already on a climb and then the gradient gets steeper.

    The business end of your crack pipe is hot to the touch!

    You can always go with an Effigear if the Pinion shifting methods aren't to your liking.

    That's really great feedback, thanks. How on earth did you get a GPI before superfan @Zaf?

    If anyone (hint hint) is willing to let me touch their gearbox bike I'm happy to be converted. Although I think I will hold out for a couple of generations of weight loss and a Di2 or more elegant trigger shifting system.

    @Zaf, a 10s XT cassette is only going to add 200g tops to the inertia of the rear wheel. That inertia is stored energy, so it's not quite the same as energy loss through friction etc.

    Yeah, twice as much energy to accelerate.

    There are too many variables in mtb'ing to get a clear figure. For me, I got to a point where I accepted I was not limited by my power output on the mtb (that's more of a road thing) and what I wanted was stability and suspension performance that inspires confidence.
    Low central weight and removing unsprung mass is gonna be pretty unrivalled in achieving that.

    You are the very definition of early adopter for innovative drivetrain technologies, salute! I hope you are planning a shaft drive commuter sometime soon :)

    Have spent the last 4 days in Bright on holidays. Two days in the snow and two days mountain biking on mystic mountain. Those jumps on the Hero trail are bigger than they look! Top section is pretty blown out at the moment but the last 2/3rds are really fast and flowy. Props to the trail builders for putting in a decent climb up there too so I didn't have to ride a fireroad up each time [​IMG]

    Mine is the Helius AC Pinion. Had it since May, 2013.

    That's what I use the Rohloff equipped Cotic Solaris for. I couldn't live with the Rohloff for mtb duties, but it seems perfect for commuting.

    I've had Di2 since 7970 Dura Ace, then 9070, but I didn't like the look of the new 9170 so haven't fitted it to the roadie. I've had a lot of trouble with the XT Di2 though. Mostly sorted now.

    I love Bright and it's among my favourite of locations. How slippery is it now though? I'd have thought in winter it would be greasier than a butcher's shop floor...

    Every time I've come to Bright it's always been slippery. Should really come back in summer .

    Tuesday was pretty slippery on the lower trails but today was nice and tacky in most sections, unless there was a bit of standing water. The less used trails were covered in pine leaves too which added an extra layer of difficulty.

    I have to say, "Up DJ" is a fine example of how to build a fun climb. There's always a roller into a bermed uphill corner to keep momentum up. Always detoured down "Down DJ" and then back up the climb on the way to Hero.

    I love Up DJ and Down DJ. Great bit of trail and ride that with a smile on my face the whole time.

    Mainly with it losing charge. It seems the front derailleur had to be set absolutely perfectly or it will keep trying to self adjust overnight. Other than that the initial set up by DefCon Cycles was not well done at all. Front and rear derailleur not set properly, cables run badly, Di2 stem not tightened correctly, firmware update not done.

    Got my bike converted to tubeless today, some new tyres - specialized butcher grid on the front and specialized purgatory grid on the rear, andsome new shimano GR500 alloy flat pedals to replace the stock plastic ones. Only had time to get a quick ride in so far but is a noticeable difference in comfort and control.
