Shimano Tiagra Vs Shimano 105 – What Is The Best Collection To Buy?

The next normal course of action, after you invest in a road bike, is to fit it with the correct gear. The right gear will alter your motorcycle’s very sensation and work. The Shimano Tiagra and the Shimano 105 remain among the leading candidates for high-investment road bike gear. But what’s the best group? Let us make a short detour before we get to the nitty-gritty discussion of Shimano Tiagra vs. 105 and cover the basics.

Shimano Has Six Separate Groups; They Include Shimano Tiagra And Shimano 105.

A category includes a manufacturer’s set (in this case, Shimano) of mechanical parts of a bike. Each category includes brakes, shifters, bottom straps, chainsets, derailleurs, tapes, and bicycle chains.

Parts of the same category may be used, or parts can be mixed and matched from different groups. But we are not here for that, so let’s get to the subject. What is the higher group? Is that Shimano Tiagra or Shimano?

Here is a short summary of both before we jump into the key points of comparison:

This community ensures enhanced ergonomics and accessibility. It has undergone updates and improvements over the years and every time it seeks to be better. With regard to hierarchy, Shimano Tiagra is the fourth level category. This company also offers double chainsets, but is best known for its high-quality three-chainsets.

PROS 

• This community provides reliability and longevity at a fair price.
• Their brakes and their range of shifts are commendable.
• It looks premium.

CONS 

• It’s just ten speeds.

Overview Of The Community Set Shimano 105

The 105 takes a safe third position in Shimano ‘s road category hierarchy. When riders always think about having this community equipment, they see it as an improvement. And this is justified because the Shimano 105 group has a good look and a good value for money. The 105 category provides only double chainsets. The group 105 is also lighter than the group Tiagra; if that’s a detail, you’re unique.

PROS

• It is an 11 rpm, which contributes to the gear.
• It offers performance and stability.
• Most parts are high quality and look fantastic on every bike on which you mount them.

CONS 

• The 105 is comparatively more expensive than the Tiagra.

Mechanical details

In Tiagra the double control levers are 10-speed, while in the 105 they are 11-speed. The bracket is made of glass fiber plastic (GFRP) in both categories. They are primarily aluminum levers.

The change of the 105 groupset feels light, while the Tiagra is a little heavier. The former captures perfectly the snappy lever action of the Dura-Ace and Ultegra pairs.

The cables in the Tiagra category are mounted under the handlebar, close to the gears in the high-end groupings of the company. You get a taste of high-end equipment in a reasonably budget-friendly community.

Efficiency braking

The 105 category uses the dual pivot braking system SLR-EV. This design allows braking forces to equalize on each limb, so you have better power and control. You can slow down the bike with minimal pressure to the lever while you are riding.

Brakes in the updated Tiagra group offer more halt than before, but the 105 group still uses cake in this area. Tiagra Community Brakes work well when you abruptly stop, but in terms of feedback and sensation through the levers, they come a little short.

If you have a fork and frame, you can take advantage of the direct mounting option provided by the 105 groupset. This option is not extended by the Tiagra community.

Pull Power

Tiagra and 105 are both capable of handling pneumatics up to 28 mm wide. The most recent iteration of the 105-group brakes indicates a minor decline. You can then run 30 mm tires as long as the correct frame is used.

Brakes Disk

The 105 groupset has 11-speed disc brakes and the 10-speed disk brakes in the Tiagra category. The new 105 R7000 STI units seem to be more streamlined than their predecessors or even Tiagra.

The hydraulic disks in Tiagra continue to work consistently well through various models. Tiagra brakes that were fitted to Genesis Datum 10 improved dramatically its downhill performance.

Sets of chains

Tiagra chainsets weigh roughly 910 g and 105 chainsets up to 716 g. Curtain arms in the chainsets of both classes are made of aluminum and the axle is made of steel. The use of the four-arm spider configuration and the uneven distinguishing between the arms ensures that they are rigid and solid.

Both classes include 165 mm, 170 mm, 172.5 mm and 175 mm crank lengths. A 160 mm crankset from the 105 groupsets may also be selected.

The 105 groupset allows you to select from the 50-34, 53-39, and 52-36 tooth setup as it concerns chainring choices. The Tiagra group can not provide the conventional 53-39 dental set-up for racing bikes. But it has a configuration of 50-39-30 (triple chainset). For this, an additional front derailleur and a left-hand shifter that is compatible with those configurations are needed.

The 105 chainset is lighter than the Tiagra, but in a Tiagra gear bike you can set up a 105 chainset.

The Derails Front

The front derailleurs are made of the same materials in both classes. One of the main differences between the two is that the Tiagra is compatible with ten speeds and includes a wide chain ring between 46 and 52 teeth. The 105 group is designed for 10-speed use and is fitted with a chainring with 46 to 53 teeth. If you want 53 teeth and larger chainrings, you will have to check out the front derailleurs from the Dura Ace Party.

The appearance of the 105 and Tiagra front derailleurs is very different. The 105 follow a philosophy that the brand calls “compact toggle design.” It’s understood that the Tiagra front drivers move smoothly, even when under pressure with minimum noise.

Back Derails

The revised rear derailleurs of the 105 groupsets feature the shadow concept of the brand. Shimano originally designed this mountain bike style. The derailleur has been tucked into the bike to increase its sprocket. Under this design. The renovated Tiagra destroyers give long-lasting and accurate efficiency.

The derails in both groups can be used with different cassettes in short and long cage models. Short-cage Tiagra derailleurs can accommodate a 28-tooth deep socket at least while the 105 can accommodate a sprocket of up to 30 toes.

Both sets can accommodate a 34-tooth sprocket in the long-cage models. A 105 R7000 community can be easily transferred to a 40-tooth chainring.

Cassettes

Both classes have nickel-plated steel sprockets in the cassettes. With its anodized aluminum locking and spider arm, the 105 edition goes one step further. The 105 edition is available in options 11-25, 12-25, 11-34 and 11-32. Simultaneously, Tiagra has choices for 12-28, 11-34, 11-25 and 11-32 tooths. The 105 group cassettes are particularly famous for their wear resistance.

Chains

In 105 groups, the chain is lighter and narrower than in the Tiagra group. One of the key factors is that the 105 is 11-speed while the 10-speed Tiagra is. The chains in Tiagra and 105 are protected by Sil-Tec (PTFE), which helps them to operate smoothly.

Higher brackets

The bottom bracket of weight of Tiagra is 92 g and the 105 variant weights 77 g – not a big difference.

Pedals 

The Shimano 105 Group has pedals with a good low profile. These pedals can be leaned up to 31 degrees.

Price

A rapid skimming of gears reveals that the 105 is more costly than the Tiagra. But it is wrong to say that Shimano 105 is superior to Shimano Tiagra because it is more pricier. It would be unfair to say that the Shimano Tiagra is better than the Shimano 105, as the contents of your pocket are much more considerate. The gears in both groups are fitted with their own features. So with these classes, you pay for the functionality and not the goods.

What Is The Difference Between The 105 Category Sets Of Shimano Tiagra?

Their pricing is one of the biggest distinctions between 105 and Tiagra classes. The Tiagra is marginally less costly than the 105, but provides the same consistency. You might also not be able to change it to 105 with the Tiagra. However, with 105, you can upgrade partially to Dura-Ace or Ultegra groupsets.

The Final Verdict

The community Tiagra equips the bike with everything that it requires to be a trustworthy road bike. But if your heart is set to 11 speeds, 105 is your best option. Also, if you have a Tiagra-gear bike, upgrading to a 105 can be a challenge, as it will entail several adjustments in the components of your bike. You can progressively change parts with Dura Ace or Ultegra groupsets with 105-wear bikes.
