Maximilian Schachmann’s Tarmac SL7 Bike Size 2021

This is Maximilian Schachmann’s Tarmac SL7 Bike Size 2021 technical review. The German rider races the season for the Team Bora Hansgrohe with a contract until 2024.

Maximilian is an excellent time trial racer and equally a great climber making him a good candidate for a General Classification (GC) podium finish. He did win the 2020 Paris-Nice and and finished second on the 2020 Volta ao Algarve em Bicicleta. These are already great introduction lines on a profile and I am sure Maximilian will add up to the list of podiums.

He is 1m83 tall and weights 70kg at optimum form. This can be translated as being at the fine line of lightweight and powerful for this height.

For these reason Maximilian Schachmann’s Tarmac SL7 Bike Size 2021 reflect the rider style from the selection of the frame model, size and components specification.

Maximilian Schachmann’s Tarmac SL7 Bike Size 2021

Maximilian measure 1m83 and ride the Specialized Tarmac SL7 size 56cm. Specialized recommend the size 58cm for a rider of 1m83 height on its website. As I explain in most of my articles most pro riders are riding one or two sizes down for few reasons like a decrease of drag with the shorter head tube length and a stiffer frame as the seat tube and top tube are shorter.

Schachmann’s saddle is set at 780mm (confirmed by himself) measured from the center of the Bottom-Bracket (BB) to the top of the saddle. The distance between the saddle and the handlebar top grip is 582mm.

The cockpit is made of a 110mm PRO stem and a 420mm width Pro handlebar.

The crankset is 175mm long with 53/39 Teeth chainrings for most of the races.

Schachmann races with Specialized shoes fitted with Shimano Red cleats (SM-SH10) which have 0 degrees of floats.

Why Team Bora-Hansgrohe races mostly on the Tarmac SL7?

The 2021 Tarmac SL7 is replacing the Tarmac SL6 and the Venge altogether as it has been developed to take the best from both frames. The SL7 has been officially released to the public at the beginning of summer 2020 but most of the pro riders of the team Bora – Hansgrohe (and Deceuninck – Quick – Step) did actually get the new model in December 2019.

The new frame feature a longer fork and shorter head tube length compared to the SL6. The frame tube have an optimized aero shape. A big technical move has been made on the Bottom-Bracket as it is back to the good old threaded type instead of Press-fit type.

The rear triangle tubes of the frame are also optimized to decrease the drag. This can be observed with wider tubes section when looking at the bike from the side.

Overall the new Tarmac SL7 has an optimized aerodynamic design and increase of lateral stiffness taken from the Venge while staying lightweight.

For the team and the sponsor it is more practical to use only one model of bike for the whole team especially on a Grand Tour. It allows team cars to carry only one model on the roof.

As an example, on the Tour de France each team has two support cars carrying an extra two bikes for each riders of the team. Each rider of the Tour de France has 2 transponder (the GPS tracking attached to the saddle) and therefor each rider has one bike with no transponder.

Each bike without a transponder can therefore be used by same size riders of the team. The fact there is only one model of bike on both support car does optimize the availability of bikes per riders taking in account teams ensure to pick some similar size riders to support its team leaders. Thus the simplification to one bike fit all for many teams.

Maximilian Schachmann rides the same frame size as Peter Sagan, this reflect the strategy to have similar size riders to support the team leader with similar bike size.
