Jelle Wallays De Rosa Bike Size


Today I am writing about Jelle Wallays De Rosa Bike size.
Jelle has been very kind to let me know his bike setup. I am so grateful for this privilege and cannot thank Jelle enough for his disponibility.

The Belgian professional cyclist is racing with the French Team Cofidis since 2021.

Jelle Wallays lives in the western Flanders area, which explains why he can be considered a Flandrian rider. A tough rider used to race in the cold wind and rainy weather.
Jelle is a stage-winning hunter, not a General classification type of rider. He has fast sprinting top speed ability and is strong enough to win solo.

Wallays usually races most of the Frandrian classics with an incursion to the Paris-Roubaix. Then his second part of the season is the Vuelta a Espana.

Now let’s talk about Wallays bike.

De Rosa is the bike sponsor of Team Cofidis.

Jelle Wallays is 1m85 tall and weighs 77kg at his peak form. He races mainly of the De Rosa Merak, size 54cm.

His Selle Italia saddle is at 786mm height measured from the center of the bottom bracket to the top of the saddle.
The seat post has a 25mm setback, and the distance from the front of the saddle to the top of the handlebar is 610mm.

The distance from the front of the saddle to the hoods is 760mm. Top of the handlebar drop compared to top of the saddle is 100mm.
The stem is 130mm and has -7 degrees angle, and the handlebar width is 400mm, 75mm reach and 125mm drop.


Like a growing number of riders, Jelle’s brake levers are slightly oriented inward. As pictured on the link here: Jelle Wallays 84th Gent-Wevelgem in Flanders Fields 2022.

Wallays races with 172.5mm crank arm’s length and Look Keo Blade Carbon Ceramic Titanium.

Jelle races with an Ekoi helmet, Ekoi sunglasses, Van Rysel jersey and bib-shorts, and Lake CX 332 cycling shoes in white color. (In 2021 he used Sidi shoes, in 2020 he was fitted with Gaerne cycling shoes)

Like the rest of his Cofidis teammates, Jelle’s bike is equipped with Campagnolo Super Record EPS 12 speeds, and disc brake types.
The wheels are the Corima WS and MCC DX mounted with Michelin tubeless and Tubulars tires. The rims heights and tires types depend on races profiles.

Wahoo Elemnt GPS and SRM PowerMeter equip the Wallays De Rosa Merak.

Wallays Fun Facts

A fun fact is that Jelle has been racing on Campagnolo gears for quite a few years, which is a minority among the pro peloton.
He was already racing on Campagnolo when he was at Lotto-Soudal between 2016 and 2020.
Considering 17% of the World Tour peloton uses Campagnolo groupsets.

The probability is small for a pro rider to ride with Campagnolo gears from one team to the next.

Another fun fact, Jelle and his wife are running a B&B in the western Flanders town of Staden. It is a great spot to use as a base for cycling in this Belgian area.
