SRAM 11sp compatible

Sweet spot gearing for PNW Cyclocross (SRAM 11x32 is too high for hilly CX courses, and the 11x36 is too low for flat courses, but Shimano's 11x34 is just right). Fully companiable with SRAM Force1 1x11sp.

Make sure you use the supplied freehub spacer.

What's not to like?

I've been using Ultegra cassettes ever since I broke two Dura Ace cassettes. They are quiet, shift great, and if you replace your chain when needed these cassettes last for well over 10,000 miles. The only reason I just bought a new one is that I'm looking for slightly lower gears for climbing as my girlfriend is the "Fastest girl in the world" and I'm trying to keep up with her on long steep climbs.

Great for the tough climbs locally

I bought a second lighter wheelset for my gravel bike with more A road bias. My other wheelset have the same 11-34 gearing. Decided to upgrade to the HG800 from the HG700 mainly because the price was minimal and BTD'S VIP points made the cost negligible for a slightly lighter and nicer cassette. The 11-34t cassette paired to a 46/30 subcompact crankset allows decent road speeds but allows you to crush any hill on the road and all but the steepest trail climbs here locally. I have found that I can climb 16 degree fire trails with this cassette before I have to stand up and the tires skid out beneath me with a file tread tire.

Probably doesn't need to be said that you will need to add links to your chain if you are going from a smaller cassette.

Solid choice for the money

Crisp, clean shifting cassette for those who don't feel like spending the extra cash for the Dura Ace. The larger 34 tooth gearing works perfectly in the Colorado mountains or on the steep gravel roads.

Replaced an Ultegra 11-28

Very high quality and great having the extra low gears for climbing. Be sure your derailleur can handle the larger cassette or buy a wolf tooth extension. You will also need a new chain. Very pleased with this purchase.

Works well with my 11 speed dura-ace derailleur

I bought this to use when I do long very steep climbs in place of my usual 11-30 cassette. Its nice to have 2 easier gears on those climbs.

Best place to buy!!!!!

Needed an 11 speed Cassette that could work on my 10 speed wheel. Bike Tires had it and at a great price. BT always the best to deal with. I have made well over 100 purchases from them. I usually pick up at their store in Portland Or.

Great for gravel. Don't forget the spacer!

Replaced an 11-32 on my gravel bike. Nice to have the extra teeth for a little more relief when the going gets steep. NOTE that even though this is branded as an Ultegra cassette, it is actually spec'd for mountain bikes. Meaning - if you're using a road hubset you need to install the included spacer on the freehub before you install the cassette.

This is great! Allowed me to use my old Chris King wheels with an 11 speed drivetrain

With the advent of 11 speed road groups, I wanted to use my old 10 speed Chris King wheelset.

This let me use this wheelset for at least a few more years!

The casssette for the rest of us

There is no shame in getting the gears that work FOR YOU! My setup Praxis Zayante 4832, Shimano Ultegra FD-6800, and Ultegra RD-6800-GS (long cage). The HG800 11-34 was a simple drop-in replacement for a CS-R8000 11-32. I tightened the B-Screw a 12 turn but it really wasn't that necessary. I did not even have to change the chain. The derailleurs have no problems shifting small-small to big-big and every combination in between.

Low gears for steep hills

I live near the Santa Cruz mountains in California and my bike club rides frequently up very steep hills (15-20% grades). I ride 10k miles with 1 million feet of climbing annually, but past racing age. I use this 11-34 gear with Ultegra 5034 cranks resulting in a 34-34 low gear. This lets you climb the steepest hills while spinning a decent RPM and not straining your knees. Also helps on long hard rides near the end to climb hills when you're tired. If you are a 125 lb racer you don't want this cassette. It's only drawback is that to achieve the wide range there are some gaps in the gearing. I miss the 12 tooth sprocket.

Perfect addition to help with hills

I bought this cassette to help with hills as I am riding the Copper Triangle in Colorado this year. Wound up liking it so much I bought more of them to upgrade all my bikes. Fully compatible with Ultegra 8000 series derailleurs. With this cassette I could climb Everest .

Great Product

I was already running the Shimano 6800 11-32 cassette but anything I can do to help save my knees is a plus. You wouldn't think 2 extra teeth is a big deal but it is noticeable. When Shimano introduced this cassette and made it compatible with my current shifters I went for it. You will also need the 8000 series derailleur and a new chain to make it all work but when you are finished you will have a bike that can climb Everest without having to get off and walk.

A few extra teeth allows for a spin instead of grind.

This cassette fits on medium cage rear derailleurs. The gear spread is perfect so you are able to adapt your gearing to cadence when climbing.
