TRP Announces DH7 Shifting Components

We are presenting a new shifter and derailleur designed for the gravity-focused rider. The TRP DH7 series drivetrain components are the result of teamwork between TRP R&D Taiwan, TRP USA, and five-time DH World Cup Overall Champion Aaron Gwin in cooperation with his mechanic John Hall.

#TRPSHIFTINGFOCUS TRP DH7 components represent a shift in focus for the Taiwanese manufacturer. They are designed for rough and rocky rides on big bikes. DH7 is for those riders who like it steep, fast and enjoy breathtaking airtime.
“There are a wide range of bikes, riding styles and riders out there today. TRP focused on the gravity segment to launch these new components. After two years working successfully with Aaron and John on brakes, we showed them our ideas for a new TRP shifter and derailleur. When we asked them if they wanted to become part of the development team, they immediately were open to shift their focus to a drivetrain. Since then, they have been pushing and challenging us, which is why we like working with Aaron and John.“ - Lance Larrabee, TRP Managing Director.

“It is a pretty complicated project to make a derailleur. There are a lot of patents and all kind of things you have to work around, so you’ve got to be really innovative to find your own way to do things and also make it better,” said Aaron Gwin. “The thing I enjoy most working with the TRP crew is their trust in John [Hall] and I, and vice versa.”

One key feature that separates the new TRP DH7 derailleur from the category’s existing products is the Hall Lock, named after Aaron Gwin’s mechanic, John Hall. The Hall Lock is a lever integrated into the derailleur mount, which locks the movement of the B-knuckle around the mounting bolt when closed. The Hall Lock can be opened to easily remove the rear wheel. The Hall Lock’s tension can also be adjusted to better match a bike design or rider preference.

John Hall and his namesake 'Hall Lock' feature found on the DH7 derailleur.
The Hall Lock was born from an ongoing competition amongst the best mechanics on the Downhill World Cup circuit - to build the quietest bike on the track. Hall identified the movement of the derailleur around the B-knuckle as a key point for improvement for several reasons, all of which are punctuated by chain retention and noise. TRP engineers and John Hall worked closely to build this idea into the DH7’s Hall Lock feature.

A second, key, DH7 derailleur feature is the adjustable ratchet-style clutch. Depending on a bike‘s suspension design, there can be enough chain growth to feel resistance from the derailleur's clutch. Other bikes require a heavier force to manage the chain. The key to managing these differences is the built in adjustability from TRP's ratchet clutch.

Like the Hall Lock feature, the new Ratchet Clutch can be turned on and off, and adjusted for tension.
If a rider wants to free up the suspension system, he or she can back off the clutch tension, or if more tension is needed to manage the chain, it can be added.

“The end result of improvement, whether it is a product, whether it is results, just elevating the game in all areas – that’s what really drives me,” said John Hall. “Take a chance on it, it is pretty cool how the product grows on you and it becomes yours – you’ll be blown away.”

After two years of field development with Aaron Gwin, TRP expanded the testing and development process to include three additional teams in 2019, for a total of four, they are: Intense Factory Racing, Scott DH Factory, Commencal-100%, and the YT Mob.

The TRP DH7 shifter and derailleur are available in black, silver and gold color schemes. This is a first step to enter the category and TRP acknowledges there is already a well established range of cassettes and chains available. Riders will have the chance to build their preferred package around DH7. In parallel, TRP will continue to learn and build on all types of riders’ feedback and our continued experience to expand the TRP product line.


About TRP
In 1986, three friends Gary Chen, Leo Chen and Aver Tsai founded TEKTRO with 20 employees in Changhua, Taiwan. The first factory was about the size of a basketball court. The monthly production capacity was at 50,000 sets of cantilever brakes. Their business values drove their success: work dependably, design creatively, manage efficiently and keep production at the highest quality. 1999 TEKTRO launched its first hydraulic disc brake, which still is the company‘s most successful and important product. Today, TEKTRO has production facilities in Taiwan and China with over 1,200 employees and provides sales and service in Taiwan, China, Europe, and the USA. TRP was founded in 2006 and stands for TEKTRO Racing Product. TRP focus, stepping into smaller categories, like time-trial, cyclocross, and downhill, has created multiple product success stories and numerous race wins.
