In this review, one of our customer installs the new SRAM GX Eagle 12 speed drivetrain onto his bike. The new cassette, derailleur, shifter, and chain are all a big upgrade to the old Shimano 9 speed system they replaced. Read more to learn how the GX Eagle performed.
I first want to talk about the weight of the SRAM GX Eagle 12 speed groupset. I was switching from an old Shimano 9 speed cassette. I bought the 9 speed cassette back in 2008 and expected the new cassette to be heavier given that I was adding three more gears. However, it was actually lighter. I know the different levels of this groupset have lower weights, however, I've been more than impressed with the weight of this product.
This was by far the easiest cassette I have ever installed. It comes with a built-in locking ring which is very very cool. The one downside however is I had never installed a 12 speed cassette which requires a special chain whip as the spacing is different.
The performance is unmatched. I had switched from a 3x system and was shocked at the ease at which I was able to shift. The entire drivetrain was very easy to adjust and fine tune.
If I had to put one downside to this group set it would be that the rear derailleur does hang quite low on my bike. This is not an issue normally however I have noticed that I have to be very careful when going through tight rocky sections as to not hit the rear derailleur depending on my gear position.
The big plus here was actually Worldwide Cyclery's customer service. I placed the order online and selected shipping to my house within 15 minutes they had called me and said they had it in stock. They wanted to confirm that I actually wanted it shipped as they were actually only 10 miles from my house and I could pick it up today if I wanted to. I was on the trails that night with my new groupset.
