Highly recommended for anyone with an 11S setup wanting more low end
by nyc2pdx

Replaced an aging 11-32 cassette on my road/gravel bike with this - what a game changer. As someone who climbs ~2000ft/day during Summer/Fall I can tell you it makes a difference. Also lets you ride in the big ring a little bit longer before shifting down. Helps you achieve the higher cadence you couldn't before during steep inclines, when you have no gears left.

Great product. Works well if you do a lot of climbing.

Shimano Ultegra are quality products. I ride a road bike in an area where there are a lot of hills and do a lot of climbing. The 11/34 cassette works great for the areas I ride.

Worked perfectly
by Rick
Vancouver, WA

I�m an older cyclist and needed a gear range that would make hills a little easier to negotiate. Installed the 11/34 cassette and have had no problems with shifting. Gear shifts are smooth. Had to make a slight adjustment with the rear derailleur is all.

Doing a tour of Utah and Colorado. Decided to get a lower gear for the altitude climbs. Fit perfectly on the Shimano wheel in place of an 11-32. Did not need to shorten the chain, just a turn or 2 on the B screw.

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.

SRAM 11sp compatible
by PNW Biker
Competitive Racer

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.

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.

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.

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.

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.

Largest spider is bad design. Third from largest cog is too close to second from largest and fourth cog also is a little wonky. Several reviews I read before buying this warned me, but I reckoned Shimano would have corrected the problem. Nope (. Going back to the 105 cassette until their gravelCX groupset is available.
