The Good: - Keeps the chain in place
- Easy to install (despite some adjustments)
- The N-R-W adjustments (for adjusting the guide according to your chainring) makes the installation much more easy than other models that you have a sliding adjustment (like the older models or MRP G2)
The Bad: My chain guide cracked in several places in the first couple months of use, but the cracks never got bigger. Despite the cracks the chain guide works like a charm and after almost 2 years of use the it was still going strong.
The pulley worn out and I couldn't find a replacement anywhere near me.
