My preferred range of gears

I live in an area that averages about 80ft of elevation gain per mile. I have 50-34 crank in front, so I do have a 1:1 ratio with this cassette. It is awesome on the long climbs. I have done mountain passes like Independence Pass and Vail Pass. I don't know if I would have survived without it.

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.

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..

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.

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.

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.

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.
