E Thirteen Extended Range EX Cog

1x Drivechains are everywhere you look this season from complete bikes to winning enduro rigs. Everyone is doing it so why should you have to miss out? With the e*13 EX Cog range extender you don't have to. Simply fit this sprocket to your existing 10 spd cassette, using the clear instructions provided, and say goodbye to your front shift setup.

Features:

  • It's an add-on cog to extend gear range of 10 spd. Shimano™ and SRAM™ cassettes.
  • It comes in 40t and 42t for use with Shimano™ cassettes and a 42t only for use with SRAM™ cassettes.
  • Installing your EX Cog is easy. Remove the 15t or 17t cog from your cassette, place the EX Cog on your freehub, then install your existing cassette back in place.
  • Each EX Cog is timed and ramped specific to Shimano™ and SRAM™ cassettes.
  • The EX Cog comes with a longer steel replacement, B-limit screw for your derailleurs. Your current one won't be long enough to get the best shifting up to the new cog.

Rated 4 out of 5 by non per tutti si perdono 2 rapporti lunghi e uno corto ( montando una corona 30t) sul rapporto 42/30 si è come se si usasse il 33/24, costruzione eccellente, ma non adatta a tutti mi mozzi sul wtb laser necessita di spessorare la ruota lbera con circa 10/10 di m.m. tra cuscinetto e corpetto forse ciò deve essere fatto anche su american classic dato che sono simili come costruzione montato su ancillutti fry con cassetta sram 1030 pignone 16t shimano xt 9v rifasato di circa 90°(al posto del 15t e 17t cambio sram x9 10v (no type2 )gabbia media catena non scorciata ,prima era per 36/24 risparmio totale 510g catena kmc x10 per ora funzionamento eccellente 11 August 2014
Rated 5 out of 5 by Perfect I decided to buy this product instead of Hopes T-Rex because of the 42 teeth. It works perfectly with my Sram X9 mid cage derailleur and PG1030 cassette. Maybe the problems are for Shimano components only. 05 August 2014
Rated 2 out of 5 by Flawed To upgrade to an extended range cog I also had to purchase an XT cassette. not an issue in its own right as I was upgrading to a 10 speed from 9 anyway. The issue comes from cost vs quality. For nearly twice the price of the entire XT cassette I expect quality workmanship. 1 hour into my first ride, the chain started riding up over the sprocket teeth when under load (same as the previous comment. I will also sand down the pickup ramp to solve this but should I even have to for this price. £5 more gets a Hope T-Rex which I'm sure will be made to standard Hope quality. Go for that one instead, I wish I had 02 August 2014
Rated 5 out of 5 by Great, if it doesnt start jumping! 2 rides in and the chain started jumping up and over one length of teeth when you put the power down. Not off the cassette, straight over some teeth! Very frustrating and couldn't figure out why for 2 weeks! checked and adjusted alignment/cable tension, hanger straight, b tension, chain length, nothing helped! Until I saw on a few teeth, a small bump/notch was starting to develop half way up, on the inside where the shifting pick ups are machined. A small bit of sand paper and 5 sanded down pick up teeth later... problem solved!!! 5/5 after this fiddle... Pics attached 21 July 2014

Answer: 
Afraid not. Your cassette wont break down into sufficient parts. They are for XT 10 speed cassettes (and SRAM equivalent). The 15 or 17 tooth cog and spacer must be removed to make room for it.
