Van der Haar’s Giant TCX Advanced Pro comes to fruition

Dutchman wins Valkenburg World Cup aboard stock version of prototype he won on in 2013

The diminutive Lars van der Haar stands tall in the world of cyclocross. At 169cm / 5ft 7in, Van der Haar is always a threat on the World Cup circuit. Here we take a look at the size small bike he used to win the Valkenburg World Cup for the third consecutive time.


This year, Van der Haar raced a production version of the Giant TCX Advanced Pro on the technical course in his home country of the Netherlands. Van der Haar won his first Valkenburg World Cup in 2013 aboard a prototype version of the bike.

The TCX Advanced Pro carbon frame features a so-called D-Fuse composite seatpost. With its D-shaped profile, the D-Fuse looks similar to a truncated airfoil riders are now used to seeing on aero bikes. Here, however, the shape is designed to allow vertical flex without adding weight, compared with a traditional round seatpost.

At 5’7” (169cm) van der haar rides a size small tcx advanced pro with a 90mm stem and 42cm wide bars: at 5’7” (169cm) van der haar rides a size small tcx advanced pro with a 90mm stem and 42cm wide bars

For 2016, the TCX Advanced Pro received a 142x12mm rear thru-axle to complement to the front 15mm thru-axle that bike has had for a while. 

Shimano is a major partner of Team Giant-Alpecin, and Van der Haar gets a full Dura-Ace Di2 drivetrain the unusual 46/39 ring combination. Shimano BR-RS785 hydraulic brakes and Shimano tubulars round out his bike.
