>>1490638"Endurance" = more upright and therefore slower but very slightly more comfortable (if you're the kind of person who thinks upright is more comfortable)
"Race" = gofast, but you can always engage boomerstem mode and/or get slightly fatter tires if you've got back problems or something. Check to see how fat of tires you can fit before you buy anything, but if you're riding on pavement with anything wider than 28mm you're a pussy.
