I'm in the market for a pack with spine protection, then… not available in the UK.

Pit Walk: EWS Round 3, Ireland
I thought it was XC racers that are the weight obsessed. I wonder how much you weight you can save doing that? Next time I go to buy some tyres I'm taking some scales!

Second Life - Video
This is exactly the reason e-bikes should exist, along with those who suffered injuries. I'd hate to think that I couldn't get out and ride due to injury or illness.

At the top, the reaction force must be at least equal to his weight. This is so that his wheels are pressing against the ramp. If his wheels aren't pressing against the ramp he's falling. So if he were to travel only just above zero, then he wouldn't press into the ramp enough and he'd fall. Like if you've ever been on a gravity wheel at a fair ground. Like you said, we haven't taken any drag into account plus, it may be elliptical so these are only very rough figures.

Two Days Left to Help Matt MacDuff 'Raise the Loop'
I got that he needs a start ramp just over 15 metres high and needs to hit 62km/hr AND I'm prepared to show my working. ????????

Join Kona in the Alps on the All New 2016 Precepts - Video
Could someone explain the main differences between the process and precept in terms of suspension kinematics, ride and manufacture? I'm just wondering what makes this bike their budget offering. There must be differences in terms of the frames performance, or is it down to the spec of the kit on the bike too? Cheers.
