One other. I’ve never seen a SunTour flip flop but like the idea a whole lot. Standard or normal or medium gear for Brit when your bike was new was 48x18. Since there is no other definition of medium gear 48x18 is still it. Higher is a big gear, lower is a small gear. The tradition for the hard men was to do early season TT in fixed gear, fenders and maybe even clinchers until they broke the hour in that 48x18. Only then did they turn the wheel around and fit the derailleur. I’ve only done a few rides on mine with a fixed wheel, you can tell the bike loves it.
