MRP 2X Chain Retention System

MRP 2X Chain Retention System

Designed to work with the growing number of 2x10 drivetrains, the 2x is equipped with MRP’s integrated skid chainring protection and a dual pulley tensioning system that ensures the chain is properly tensioned. It also reduces drag and noise while keeping weight low by eliminating the need for a full bash ring.

MRP 2X Chain Retention System Features

  • Compatible with 9 and 10 speed drivetrains
  • For two-ring drivetrains.
  • Integrated skid protects chainrings and glides over rocks and obstacles
  • Modular skid saves 40g when removed
  • Patent-pending dual pulley design provides precise chain engagement while reducing noise and drag
  • Raised top fin profile prevents the chain from dropping to the BB shell

Exactly what I expected... noiseless!!!
I ride a 2010 NS Surge frame with an All Mountain/Enduro set of components (160mm). The real noticeable thing about the quality are the pulleys that allow the chain to roll smoothly through the tensor. Absolutelly no noise. Used to ride with a Gamut but this one is way better. Awesome product. Easy to install, fitted perfectly.

Works, but expect slight drag
The MRP 2X was very easy to install. It comes in ISCG, ISCG-05 and BB mount. My remedy has ISCG and it was installed very easily. All the reviews I've read said they felt no drag, but I have to admint I felt it just around the street at my house, not much but it was there. It does keep the chain tight and I could not produce any slap whatsoever.

PROS: Easy To Install, No Chainslap

CONS: Chain Drag, No Real Chain Guide

BEST USES: All Mountain, Freeride, Mountain Biking

Top Notch Problem Solver!
Three months of use, a bit of noise but no perceived drag and functionally excellent. I was dropping chain up front even after tweaking Shimano 2x derailleur. Chain would get badly wedged between ISCG tabs and chainring, taking a lot of time to and effort to remove. Installation instructions' "matrix" was way off for my Giant Trance, but once I got the chainline right, the dropped chain problem has completely disappeared. Bashguard is excellent. This item is more than worth the cost, time to install, and weight gain. I will be running 2x for everything but XC from here out, and the MRP 2x guide will be on every build!

PROS: Functionally Excellent, Bonus Bashguard

Nice looking guide
At the moment the chain guide is sitting on my bedside table. I really like it here as it doesn't take up much room and has its own attractive black pull string bag which keeps it in pristeen condition. The bag has MRP on the side, so I Can identify it easily if I get another small black pull string bag. Before I go to bed I like to spin the two guide wheels and imagine what it would be like attached to a bike. So far I am very impressed with its flawless performance.
