Why We Like The XT FC-M8120 1x Crank Arms
We may as well put ‘Deore XT’ in the dictionary as a synonym of 'quality'. These Shimano XT FC-M8120 Crank Arms are built for us to put them through the wringer. Seen on our cross-country and enduro bikes, they’re light enough for all-day trail use and durable enough for us to throw down on big park days. The newest XT offering is equipped with a cinch chainring to minimize creaking and weight while working with the latest and greatest Shimano 12-speed drivetrain systems.

It’s what you expect from XT
- Familiarity:
- I've used it once or twice and have initial impressions
Caught this on sale for what SLX normally sells for and I couldn’t be happier. I am a bigger rider and I don’t worry at all about the cranks holding up.
