Strengths:    least expensive, 42T sram specific version

Weaknesses:    can bend under load

Bottom Line:   
I was waiting for someone to come up with a cheaper alternative to Wolf & OneUp for 42T on sram, and waiting when I heard of E13. been using this for a year with little problems with sram 1070 11-36, x9 type2 RD (after initial skipping issues due to loose freehub on my CB Iodine 3 wheels, no issue on newer Ibis/Novatec hub). Having that extra 42T range really helps my 1x10 setup and been happy - chain had to be 2 links longer than my origial 2x10 due to X9 type2 RD not flattening all the way when the B screw adjusted to clear the big 42T cog.

However today I bent the ring during a bad shift going up hill - I did the same thing on an sram 1080 (large cog also ALU and after a replacement never used it and went back to steel only cogs) but I think the design isn't as good as say Wolf where you have EVEN spacing between the teeth support (as opposed to E13 have 5 teeth in the bigger gab where it bent) AND having tabs that presses against the 36T steel cog. The E13 cog is flat (has some grooves) and doesn't get supported by other cogs. Cheaper but not as durable IMO.

Strengths:    Provides good gear range at reasonable cost

Weaknesses:    quality issue, but that got resolved

Bottom Line:   
Brought from my LBS along with new XT cassette and Sram chain.
Easy to fit (I like doing my own mechanic stuff) but couldn't get it to run right, kept riding off the Ex cog.
Took to my LBS (Freeridn Kumeu Auckland New Zealand) to try and sort out, he had a few goes, but no go.

He finally measured the thickness of the Ex cog and found it to be 2.3mm or so, this meant it was to tight on the chain and causing chain to hang up on cog, like chain suck,

E 13 supplied a new one (1.9mmm thick) and it now works a treat, so happy as.

Strengths:    Gives you 42 teeth.

Weaknesses:    Was not compatible with my Stans 3.30 hub. My XT derailleur was not happy. A good idea that creates a bad experience - at least for me, but could work for others.

Bottom Line:   
I was excited with this product, and have many E-Thirteen items of high quality, BUT this one is going back. I started with a brand new XT cassette, new XTR chain, with existing XT shifter, and XT derailleur - modern 2013 models. The cog made contact with the hub (Stans 3.30 w/ EX Arch rims) causing chain suck and drag/rubbing; a 1mm space fixed the problem. The B limit screw does not work on my XT derailleur as it crests the top of the limit stopper effectively making the screw non functional. When taking out the 15 or 17 stock cog it really screws up shifting - remember Shimano made those ramped cogs to step together, so deleting one caused skipping and a little extra manual shifter push to make the jump at the missing cog. Once on the 42 tooth EX Cog the chain skipped and jumped and was generally noisy; no adjustment of the B limit screw up or down remedied the problem.
When returning to straight stock cassette setup the rubbing, bad shifting, and skipping went completely away. Quiet as a mouse now. I want to like the Ex Cog, but I cannot.
