I didn't mean an off-road segment - just a fast ride down a road
Round here there are segments that line up nicely with prevailing winds, so when theres a stiff southerly, riders go out into the headwind then turn and smash-back at four-times the speed. Or more
a 40 km/h headwind is awesome once its a tailwind.
Fun fact: the head angle is 70 degrees according to this table from Evans Cycles. Yet the Cannondale Trail (2017) which is a "sport" hardtail has a steeper head angle of 71 for the 29" version.
Though they fixed this in the 2018 version and set it to 68.5 degrees.
@CristianCiupitu A boom is the pokey bit out the front. It supports the bottom bracket/cranks/etc. Has to be adjustable for leg length, which adjusts the chain length with the two idlers/tensioner underneath (a "chain gobbler" in this manufacturer's parlance)
This one has a round boom and it is only held by two QRs, so a good push made it move, rotaring the chainring 20 degrees off. Doesn't work well like that :-\
