Kmc X10sl

16989 Views 51 Replies 27 Participants Last post by  phlegm
I just got a X10SL chain from chainreactioncycles today, it was in a long rectangular zip-lock style bag with just a sticker saying KMC X10SL. It is a silver one, and with grease it weighed 250g even. Also it didn't come with a missing link :madmax:

So is this the older one? or the newer one? any way to tell?
also since it didn't come with a missing link and I don't have one what should I do? send it back? order a missing link? will a sram powerlink for 10sp work?

Thanks,
Colin.

I got my 2010 off ebay uncut with missing link was 246.645 grams.After I cut it it was 238.14 grams. The sram 10spd powerlink will work.
the 2010 version has just one larger slot in the plates, whereas the earlier versions have two smaller slots
I'd be emailing CRC to let them know they need to send you a link pronto...... check the exact product you bought first to make sure it was supposed to come with a link.
Normal KMC chains come in a small square box.

PBK has some good prices on these at the moment...$65AUD
A german guy just posted some comparison numbers from "old" version and the "new" one.

It seems the new ones gained about 8-10g over the previous version. As mentioned already above the new ones have just ONE slot in the sideplates while the older ones had 2 slots.

Ad they defintely should come with missing link!

I've got the 2010 version - think it was about 248g out of the box and ended up at 237g when trimmed to size.
I prefer the "missing link" to the SRAM version as their 10speed link isn't designed to come apart like the 8 and 9 speed versions, which is a bit of a PITA if, like me, you remove your chain to clean it.
by the way, i went from the old version 9 speed to the new version 10 speed and am amazed at the performance improvement. the old 9 speed shifted like butter and the new 10 speed is even better
I dont want to hijack this thread, But Im going to be buying a gold KMCsl within the next month for next season and I have an 11-34 casette 2x9, I have heard about shifting problems with using a 10spd chain on a 9 spd drivetrain. How have you guys had any problems with them? The weight savings is pretty decent, so If I can get away with using the 10spd then im all for it

If it matters I have an xt casette

Running the same 11 -34 & 2 x 9 as you with KMC 10sl & shifting is excellent.I like the shifting on this chain better than XTR & Sram hollow pins
Alright, thanks guys. I do have the new one then, and I will be sending an email to CRC to try and get the missing link.

Thanks,
Colin.

I was running a 9 speed KMC and switched last weekend to the 10 speed I did a 6 hour race on it this Saturday and the shifts felt great works superbly
pernfilman, was that the boulder 6hr?

It was the Boulder 6 hour and it was chilly, did you race it also?

Yeah I was there. It was definitely cold, coldest I've ever ridden in.
How did you do out there?

EDIT: just noticed your thing said 'The Missing', I think I raced you at Solavaca.
I raced Solovaca as well First place cat 2 senior men

5th overall open class at Boulder

Coldest I have ridden in for that long it was something else, how did you do ?

Yeah I came in second at solavaca in that class.
Nice! I got 17th in the open class at boulder (not enough endurance)
Any idea if most online shops selling these chains would still have old stock left that they are selling? Can anyone confirm who is currently selling the 2010 chains?
