ShimanoUltegra CS-HG800 11-Speed 11-34 Cassette(Return to Product Page)

Good enough for flat, great for steep climbs

11-34 ultegra cassette is what allows this older cyclist to climb�5000 miles on my current ultegra

There are steep hills in the Islands , so I opted for this cassette... Im not too thrilled with the spacing of the gears, but it performs as well as can be expected..

No issues so far.

Was looking for a little extra help up the really steep climbs. Western Bike Works had exactly what I needed and always at a great price. Their customer service is as good as it gets. Theyve earned my loyalty for sure.

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.

Used this instead of my old 1132 cassette this year at DK200 to make the 11,000 feet of climbing a little easier and it did the trick nicely. Worked great with an Ultegra chain, compact crank and a GS rear derailleur Di2 set up. There was plenty of take up to keep the chain taught on the rough stuff cross chained and enough clearance on the 34 tooth cog with the B screw tightened up a bit.

I use this with a Wolf Tooth extension to provide me with an extreme climbing gear when I'm in the mountains, close to the end of a long day and down on watts.

Top quality Shimano cassette, this cassette is about an ounce lighter than a sram one for the same gear range and shifts a bit smoother on my one by cross bike. The extra low end is a plus on some of the steeper cross crusade courses like ninkrossie.

Perfect fit. Great quality.

Product is as stated! To be of Excellent Shimano Quality! Would recommend All to get their Bicycle Accessories from Western Bike Works! Awesome service as well!

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.

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.

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.

A rock solid, well made product. Shifts are smooth and quiet.

The cassette was delivered without any issues. I gotten installed for an upcoming event that required some climbing elevation. I wanted to be ready. The cassette works great.

As alaways you get what you pay for, it's pricey but worth it for the quality and smooth shifting.

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.
