What is the difference between Shimano 105 and Ultegra cassette?

What is the difference between Shimano 105 and Ultegra cassette?

Cassette. Both 105 and Ultegra are 11-speed systems. In both cases, the sprockets are made from nickel-plated steel, although an Ultegra cassette has a carbon/aluminium spider arm and an anodised aluminium lockring while a 105 cassette has an aluminium spider and a nickel-plated steel lockring.

Do I really need Shimano 105?

If you want really low gears, 105 is the better choice. In theory both systems will handle a 34-tooth largest sprocket, but while we’ve heard of people persuading Tiagra to cope with a 36-tooth, we have direct experience of a long-arm 105 mech cheerfully shifting to a 40-tooth sprocket.

Are Ultegra cassettes worth it?

Yes, the Ultegra cassette is worth the extra money. No, the Ultegra rear derailleur is not worth the extra money. You can run a 105 rear derailleur on an otherwise Dura-Ace system and not tell the difference.

Does Shimano GRX work with 105?

Shimano’s GRX for gravel and 105 for road bikes are compatible with 105, 5700 and above; as of February 2021, there are no 105 models with Di2 electric shifting, so GRX Di2 models are not compatible.

Is Shimano Ultegra good for gravel?

That said, the Ultegra RX derailleur is still a solid option when it comes to gravel riding, especially if you don’t intent to bash around on crazy rough trails and gravel roads. If you are going to use your gravel bike more like a mountain bike, then the best option might be to stick to the GRX line-up.

Is ultegra faster than tiagra?

Tiagra is equal to 105, minus one gear. The only performance upgrade of Ultegra over 105/Tiagra is the new 6700 crank. With the outer ring being forged, front shifting is more precise. Rear shifting is very, very similar.

What is the difference between Shimano Ultegra and Shimano 105?
