Is Ultegra 6800 GS compatible with an HG800 11 speed 11-34 cassette?

5 min read

Asked by: Chris Barton

Yes, it is that one! And the front rings are 52-34. In fact I have three different cassettes that I swap 11-25, 11-28 & 11-32 without changing the chain which is adjusted to fit the 11-32.

Does Shimano make a 11 34 cassette?

The Shimano Ultegra CS-HG800 11-Speed 11-34 Cassette provides wide-range gearing that covers the low end while giving you bigger gears for bigger climbs in rough terrain.

Are all Shimano 11-speed cassettes interchangeable?

SRAM and Shimano cassettes, on either road or mountain bike, are interchangeable with each other as the spacing is the same between the sprockets.

What is HG800 cassette?

Compatible with GS cage rear derailleurs, the HG800-11 cassette offers low climbing gears perfect for mixed surface riding. It is compatible with both 10 and 11-speed freehubs.

What speed is Ultegra 6800?


Ultegra 6800 has a rider tuned drivetrain. Rider tuned means that riders can individually choose a large variety of gearing options for all kinds of riding, whether you ride races, Gran Fondo’s, sportives or cyclocross. The Ultegra cassette is going 11-speed. From 11-23T all the way to 11-32T.

Is an 11 34 cassette good for climbing?

All other things being equal, the 34T sprocket on the 11-34T cassette is going to give you the easiest gear. If your bike is currently fitted with an 11-28T cassette, switching to an 11-34T cassette will make climbing less of a struggle.

What is the biggest cassette for ultegra?

The 11-34T is the biggest cassette that Shimano recommends for use with its road groupsets.

Can you mix Shimano groupsets?

It is possible to mix and match as long as you get components from the same generation. For example: 9000 Dura Ace, 6800 Ultegra, and 5800 105 are all cross compatible. Each have 11-speeds in the rear, use the same cable pull per shift and use the same front derailleur design.

Which cassette ratio is best for climbing?

Here’s the short answer:

  • The best mountain bike gear ratio for climbing is 46 to 49 on a chainring and 16 to 18 on a cassette. …
  • These can consist of chains, front/rear shifters, cassettes, front/rear derailleurs, and chainrings.

What is the best gear ratio for climbing hills?

You will need even lower gear ratios for steep hills that are 8% or more. The most preferred gear ratios on such tracks are 50/34, 40/34, 36/40, 34/36, 34/32, 34/30, and 32/20. However, remember that using gears with such a low ratio will cause you to pedal more, but it will require less effort.

What is the difference between 105 and Ultegra cassette?

The only difference between them is that the 105 chain has this treatment on the roller link plates (the inner ones) only while the Ultegra chain (above) has it on the pin link plates (the outer ones) too.

Does 11 speed cassette need a spacer?

The answer is yes, you do need a spacer with an 11-speed cassette, but only if you run your 11 speed Shimano or SRAM drivetrain on a 10 or 9-speed freehub.

How do you read a bike cassette?

Quote from video: – numbers mean it. All comes down to gearing. So to make it simple the numbers indicate the smallest. And the largest number of teeth.

Is a 11/28 cassette Good for hills?

When you have built up your leg muscles and are powering up most hills, swap a lower range cassette, such as an 11-28, back in. You don’t need to do this if you are a frequent cyclist, young, with strong legs, fitter than average, or if you live in a flat place with no hills.

What cassette do pro cyclists use?

The most common cassette size used in the peloton is an 11-28t. That is positively humongous compared to the 11-21t cassette that was common a few decades ago when you’d be lucky if you got an 11-23t for the mountains. Since Shimano went to 11-speed though, the 11-28t cassette has become popular.

Does the number of teeth on a cassette matter?

What is the max cassette for short cage derailleur?

All derailleurs have a maximum cassette size. This is often indicated as the maximum number of teeth that can be on the biggest cog (often referred to as low sprocket max in manuals). So when you see that a derailleur has a maximum cassette size of 30T you know that the biggest cog on the cassette cannot exceed 30T.

What is the difference between 105 and Ultegra cassette?

The only difference between them is that the 105 chain has this treatment on the roller link plates (the inner ones) only while the Ultegra chain (above) has it on the pin link plates (the outer ones) too.

What is a 50 34 crankset?

Compact chainset

A compact chainset has a 50-tooth outer chainring and a 34-tooth inner chainring. This means that the gears are lower (easier to turn, but they’ll progress you a shorter distance per pedal revolution) than you get with a 53/39 chainset (above) with the same cassette.

What does total capacity mean for rear derailleur?

Rear derailleur Total capacity

It is the maximum amount of chain slack a derailleur can take up or let out, expressed in a number of sprocket teeth. Exceed the total capacity, and your chain will likely be too long or too short for some combinations of gears.

What does GS mean on Shimano derailleur?

medium cage

Shimano rear derailleurs are available in two types, SS (short cage) and GS (medium cage), depending on the model. The “cage” here refers to the length of the pulley cage (the unit that houses the two pulleys).

What is a GS rear derailleur?

“-GS” refers to medium-cage rear derailleurs, built with a maximum chain capacity of 37T to 39T or less. This is usually the longest cage offered for road bike rear derailleurs, but also the default “short” option offered for their mountain bike counterparts.
