Posted by bturman on 5/25/2018 8:02 AM

The Good:

Range for days, Looks the part

The Bad:

Weak non-adjustable clutch can't control chain slap, numerous jams and blown jockey wheels/mech cages, sensitive B-tension. Chainring is soft as cheese. Stupidly expensive and the mech hangs down a long way.

Overall Review: I ran X01 Eagle on my bike for three months over summer. Riding a few times each week and racing 4 one-day enduros and one 6-day trans event. I had numerous problems with Eagle. Not so much in terms of shifting. It moves up and down through the the block quickly and consistently. (Though it's ...

How-To: Fix Common Rear Derailleur Shifting Problems (video)

The rear derailleur is the heart of most mountain bike drivetrains. As the 1x drivetrain becomes standard issue on capable cross-country, trail and enduro bikes, we're left with one shifter, cable and derailleur to adjust for top-to-bottom gear range performance. GMBN has put together a handy gu...

For the last year some friends and I have been toying with the idea of riding the Colorado Trail from Molas Pass to Durango – a ride actually deserving of the word "epic." Three weeks ago we made the high-country adventure happen. We planned to tackle the beast over two days with a sag-wagon ful...

When you look back at the history of SRAM's 1X drivetrains, it took quite a while for all that wonderful technology to trickle down to a price point that many considered to be affordable. Three years and multiple intermediary drivetrains separated the 2012 introduction of XX1, the company's flag...

Guerrilla Gravity BFC Cog (product)

On a summer trip to Whistler, a few friends and I ditched the lift line in favor of the lesser traveled trails on nearby Blackcomb. The ride began just like any other - popping wheelies and cracking jokes as we made our way to the base of the mountain. Then the pitch kicked up a few notches. My ...

The Good:

Light weight with a claimed weight of 303 grams, or 287 grams depending on what page of e*thirteen's website your looking at. I didn't measure it, but it feels much lighter than the Shimano 11-46 cassette it replaced. The gear ratios are well thought out and feel closer together compared to Shimano's XT cassette. Shifting is buttery smooth, even after two months of use. The 9 and 10 tooth cogs really let you get moving on downhill and flat sections. No unusual squeaks or weird noises as of now.

The Bad:

This cassette is expensive even by SRAM standards. Shifting into the 9 tooth cog isn't as consistent as the remaining cogs. Sometimes it takes a couple pedal revolutions to get it to grab the cog when paired with a XTR derailleur. Ironically, shifting is quicker and more consistent with a XT derailluer.

Overall Review: This cassette offers much better performance, range and weight savings compared to Shimano's 11-46 XT cassette. I've been running it for a couple months now and it works just as good as the day I installed it. Tooth wear looks minimal to non-existent at this point in the cassette's life; however...
