What's your choice?
On_one are doing the 971's for a tenner, which although is good, the 991's you can pick up for 20 when on offer...?
971's wont be good enough for you 😉
😆
on-one do the 991's for £17.99
I'd still prefer KMC
951's work a treat here.
Kmc x9l
Ebay
951 are fine
KMC last longer
No performance difference between the 971 and 991 though, maybe a few grammes but that's it.
For £9.99 each, it is indeed cheaper than trade price for sure.
What's meant to be the spec difference between the two?
971 outer plates are chromed. 991 inner and outer plates are chromed IIRC. KMC still last longer. Cheap chains a false economy if causes Cassette to wear prematurely
No. SRAM 991's are bright nickel coated.
had 951/971/991 on various bikes, just get the cheapest, you wont notice any difference
991's are twenty better
Are the power links the same?
Best bit about a pc991.
If its a choice between the 2 Sram then get the 971 ,once its covered in oil and mud it wont make any difference.
Although my money goes to KMC ,not much difference in shift quality but found the Sram ones seem to rust quicker and stretch sooner.
Neverr tried a KMC. The Shimano's seem to last a few months at best.
Which KMC would you recommend?
KMC X9.93 are great - rust free, long lasting, excellent shifting.
Does KMC use the power link system?
I have not used KMC but it looks like thay have own power link system http://www.chainreactioncycles.com/Models.aspx?ModelID=25439
