Belgian bike maker Jaegher and internal 2x hub maker Classified have paired up in Flanders to build the ultimate 1x all-season, all-road bike for Belgian Classics champ Tom Boonen. Starting with the Jaegher premium, custom stainless steel Ascender Pure road bike, the bike is one of the first to get Classified Cycling’s unique electronic, internally shifting hub to double the gear range of the otherwise single ring Dura-Ace Di2 drivetrain.
And while Boonen’s Jaegher + Classified super bike is far out of most normal human’s price range, Jaegher offers other complete Classified 1x 2x builds at around half that price…
Tom Boonen’s Jaegher + Classified Ascender Pure steel road bike
Boonen’s “Perfect Bomb” Ascender Pure isn’t the first premium steel road bike we’ve seen from Flemish bikemaker Jaegher. Always equipped with color-matched ENVE forks, Jaegher was one of the bikes to feature their all-road fork at Eurobike a few years back. Handmade halfway between Bruges & Ghent by a team led by a fourth-generation Flemish steel framebuilder, Jaegher balances tradition and modern tech since 2012. That made the fit with fellow ‘virtual front derailleur’ Classified Cycling also from Flanders make sense.

And seeing as how Boonen invested in the drivetrain maker, what better excuse did they need to build up a premium Classics-inspired steel road bike to survive riding in Flemish weather.
Jaegher Ascender Pure premium stainless steel all-road bike
The Ascender Pure bike itself is Jaegher’s most expensive bike. Welded from Columbus XCR stainless steel, they say it gives the best balance of lightweight (claimed 1400g) & stiffness. Finished framesets sell for 4395€ (all prices with VAT, 3632€ for non-EU buyers). That includes full custom geometry and a matching ENVE fork – either with a brushed finish & ceramic -coated logos, or wet paint. Disc brakes are standard (rim brakes are still an option, though), as are internal routing, T47 BBs, choice of seatpost size, 12mm thru-axles, compatibility with any drivetrain, and 32mm tire clearance.
