Ultegra vs. 105 Cassette – How do they differ?


If you are looking for an impressive performance, Ultegra and 105 Cassette are built for the job. One thing you need to consider is the kind of results you want to get with these products. For example, Ultegra is quite light but it is also durable. This means that you can comfortably use Ultegra for racing as well as on the long rides across tough terrain.

For 105 Cassette there are many riders who can swear by the exquisite performance you get with it. While Ultegra sure has its big selling points, 105 Cassette is still on the map because most riders really enjoy the consistent and stable workouts you get with them.

While Ultegra is the more recent group set, the 105 Cassette does not shy away in delivering an impressive performance.


While Ultegra and 105 Cassette belong to the same group set (11-speed) they do have their structural differences. First, the Ultegra has a sleek and more refined finish than the 105 Cassette. This is because it is subtly designed with durable coatings and light-weight materials. While the weight difference between them is almost negligible (200g) you get a different kind of design with the Ultegra.

To add, both the Ultegra and 105 Cassette are designed with Hollowtech technology to make them firm and stiff while still as lightweight as possible. 105 Cassette is also designed with Trickle Down technology.

Both group sets are built to be efficient but still with an eye-catchy design.

Gearing and Electronic Shifting

If you are looking for the best tech-features a group has to offer, you need to consider the gearing and electronic shifting. With Ultegra, you get an optimized set that delivers on consistent shifting by the pairing up of the chain, cassette and chain rings. On the other hand, 105 Cassette has a rather mechanical system that is quite bulky.

As for their gearing, Ultegra and 105 Cassette offer the same kind of options. They both come with short and mid-cage derailleurs that have the same requirements.

While the Shimano Ultegra is quite pricey, it does come jammed with the premium quality features making it well worth the buy. First, its design has been tweaked to make it easy and comfortable to use. For example, the shape of the brake lever makes it easy for you to wrap your finger around it for smooth braking. If you want to hard brake, you can also quickly add all your fingers to it to come to a hard stop.

Secondly, Ultegra is manufactured with carbon-fiber plastic brackets that are reinforced. This is partly why they are more expensive but you do get a compact and lightweight product that is easy to use.

With Ultegra, you also get specially designed chains that go through a Sil-Tec friction plating process. This means you get a smooth running chain that requires close to no maintenance.

As for the pedals, Ultegra has stainless steel body pedals with widely spaced bearings. Together, you get pedals that are not prone to wear and tear and they give you more clearance of up to 33 degrees.

To add, Shimano usually updates its group sets every three years. With the Ultegra, the most up to date version is the R8000 so you should consider going for that. The hydraulic disk brakes are R8070 and the disc brakes are R8020.

They are also tweaked to be as long lasting as possible. For instance, the rear derailleur is designed with an aluminum cover that protects the parts from any external elements as well as absorbs all impacts and shocks.

Another quality feature of the 105 Cassette is that the new models make use of the hydraulic brake/mechanical shift unit. With a smooth finish, you get a good looking product that has enough grip to perform in the wet.

The pedals fitted on the 105 Cassette are also uniquely designed for adjustable entry and durability. They are configured to last you quite a while even with many intense workouts.
