Shimano Sora vs. Shimano 105: The Difference

The key difference between the Shimano Sora and 105 is the complex hydraulic disc brakes system that the 105 offers. It provides the user with superior braking that the Sora doesn’t offer. The Sora is unfortunately limited to mechanical disc brakes.

There are also several other differences to consider when choosing between the Shimano Sora and 105.

Gears

The biggest difference between Shimano Sora and Shimano 105 is the number of gears they offer. Shimano Sora is a 9-speed groupset, which means it has 9 gears in the rear cassette, and Shimano 105 has 11 gears in the rear cassette.

The Quality of Frame

Both the Shimano Sora and the 105 have highquality frames and are made from durable stainless steel material.

Ease of Use

The Shimano Sora and 105 both have integrated shift and brake levers that operate similarly. The user has to pull the lever back to the brake and swing it inward to shift. There is also a small button located behind the lever on both models that activates the opposing shift.

The shifters for the Shimano 105 are ergonomically designed, so they are light yet solid and provide the user with the ideal grip. It is easy and effortless to switch gears and provides the user with a satisfying click sound when you shift between gears.

The shifters for the Sora are not as refined, which can make them more difficult to operate. While the shift may be flawless, it will require the user to use more force when pulling, which can make it ultimately feel rougher than the 105.

Ease of Maintenance

The maintenance for both products is fairly simple. It’s important to use WD-40 to free up any frozen shifters and follow up with a silicon-based spray lubricant after the solvent has had time to evaporate, typically overnight.

Durability and Warranty

While testing we found that the Shimano 105 was far more durable than the Sora in more ways than one. From the shifters to the crankset and weighing cassettes, the 105 manages to outshine the Sora in terms of product durability. Both products have a one-year warranty through several retailers, including Amazon.

Weight

The 105 chainset is not only lighter than the Sora chainset (752g vs 953g), but also has been redesigned to include a newly positioned inner ring to prevent cross-chaining.

Price

The Shimano 105 R7000 groupsets currently retail for around $500 for sets with caliper brakes when considering the most current models. They cost around $700 for those with disc brakes.

The latest Sora model R3000 groupset may be purchased at around $350 with caliper brakes and for around $400 for mechanical disc brakes.

Compatibility with Cycles

Shimano Sora vs. Shimano 105 Groupset - Improve Your Bike!
It is possible to mix and match different Shimano components, as long as all the parts are from the same generation.

The Shimano Sora is only available with a choice of nine speeds in the back, and therefore you can only use this groupset with cassettes that feature nine sprockets.

The 105 is compatible with a broad range of cycles and cassettes. If you are interested in finding out if the groupset is compatible with a specific part or cycle, you will need to conduct a little research to learn more about it.

Which to Choose?

If your main concern is braking power, you can find exactly what you need in the Shimano groupset. The brand offers everything from calipers to disc brakes. The Shimano 105 disc brake features a hydraulic system that is more complex than the Sora. It offers superior braking power. The Sora, however is limited to using mechanical disc brakes.

If your primary concern is calipers, the 105 feature a unique dual-pivot design that includes options for direct mounting if needed.

Throughout our research, we found that the 105 dual pivot brakes are dependable, responsive, and more aero than Shimano’s previous models. However, the Sora’s calipers did get an upgrade. Now they have at least 20% more braking power than models had in the past. They offer an impressive bang for your buck with excellent braking capabilities, still, users should not expect the same level of stopping power as with the 105s.

Overall, we feel that the Shimano 105 is the optimal choice because it has many impressive features, it is highly durable and reliable, and it is much more affordable than the Sora.

Final Thoughts

When comparing groupsets to purchase, you cant go wrong with any of the products made by the industry leader Shimano. Over the years, the brand has decreased its technology from higher groupsets down to lower ones. This has caused the differences in groupset models to be very minimal with each upgrade.

The Shimano Sora was once looked over as a viable groupset. Today it is considered to be a great option for anyone seeking an affordable groupset when upgrading their bike.

If you are planning to upgrade your cycling, the Shimano brand has a lot to offer. When comparing their products, many cyclists will research Shimano Sora vs. 105 to understand both products better.

As we researched both products, we found that the Shimano Sora and the 105 are quality groupsets for any cycling enthusiast Trusted Source The great bicycle boom of 2020 Throughout lockdown, rusty bikes were dusted off in garages around the world and sales of new bikes surged. The question is now: can it last? www.bbc.com . However, in terms of price, durability, and capabilities, we found that the Shimano 105 was, in our opinion, the winner. And, if you are planning upgrade your sora to 105, that is absolutely worth it.
