Det är väl inte orimligt att tänka sig att det som föredras i velodromen också är det som bör vara starkast för just oväxlad cykling. Köp nåt NJS-godkänt. De kör båda bredderna men föredrar 1/8” för sprint dvs det hårdaste.

”1/8th inch width chains are commonly used for sprint
distance events on the track. At the world level,
everyone who competes in sprint events uses this
width chain without exception. The reason is that the
men (and some women) often weigh close to 200 lbs,
produce fantastic power outputs along with massive
amounts of torque, especially in standing start events
such as the Team Sprint. The stout construction and
durability of these wider chains mean they very rarely
fail under load. In fact, I can’t remember the last time
I saw or heard of a 1/8th inch chain fail”
