Bike Setup:
Miyata Nimbus being built for race

Summary:
I am currently building a road to compete with and the Shimano 105 was recommended to me. Well, I purchased it and installed it a few days later and went for a test ride. I've never been so disappointed. In the low gears, it was fine. But as soon as I shifted into the high gears, the octagon "teeth" inside the left crank stripped out so bad the crank would freespin with zero resistance

Strengths:
No strengths, absolute weak part.

Weaknesses:
The materials are incredibly poor. Yes, it is fairly light but one should make a product that is strong and light or strong and heavy. Light and weak is a very poor combination.
