How many links
 

Does anyone know how many links the ST4S chain should be with 14/15 FR. sprock and
standard rear ?

is it 102 , can anyone confirm ?

Standard gearing on ST4S - should require a 102 link 525 chain
:P

Thanks, mate - that's brill
& will order new Renthal cogs & Tsubaki chain for the weekend from B&C.

Should have read the reply more
closely.

Standard gearing ie 15 & 42 = 102 + rivet link.

Drop a tooth on the Fr. as many of us do, then its 101 + rivet link.
ie 14 + standard 42 RR = 101 + rivet link.

PS. Renthal sproks., and Tsubaki chain are the bus. Good quality gear. Much quitrer and no corrosion or stretch seen so far at all.
