The Wilier Jaroon – “A high-quality frame, welded with a special technique that hides all welding material inside, making the frame appear clean, and the seams flawless.” For more information on the Wilier company and the sister bike to the Jaroon, the Jaroon Plus, check out out our earlier article from Interbike 2016.
More about that welding process that Wilier calls “internal brazing”. Frame brazing material is inserted into the tube joints which are heated up by welding torch to the point of melting – the end result is an extremely clean looking weld that is virtually seamless.
We know nothing of welding, but can only assume this process takes some serious skill.
We are very happy to see a company such as Wilier break from the mold of tradition with their new gravel bikes – they look even better in person.
Tapered headtube for the Wilier Jaroon.
The all-carbon tapered, monocoque 1 1/8″ to 1 1/4″ fork features a 12mm thru axle. Depending on the manufacturer, front thru-axles spotted on gravel bikes at Interbike seemed to be an even mix of 12mm and 15mm thru axles. However, we expect 12mm may become the adopted standard…
SRAM Rival flat-mount disc brake with 160mm 6-bolt centerline rotor and mounting points for a fender.
Flat-mount disc brake on the rear, but Wilier opt for a 140mm SRAM Centerline disc brake rotor.
Wilier outfit the Jaroon with a Promax handlebar featuring a 12° flare. The seatpost is a 27.2mm wide Promax unit – many manufacturers have reverted back to this smaller size, touting greater comfort.
Cables are routed externally on the Wilier Jaroon. However, the rear derailleur cable appears to be sheathed in SRAM’s Gore Ride-On system – essentially, the cable is contained inside a full-length high-density polyethylene liner. We do not know if this is a production item, or just for the Jaroon show bike. Either way, this system keeps mechanical shifting smooth as butter in even the worst of conditions.
SRAM’s Rival single-chainring drivetrain is at the heart of the Wilier Jaroon. The S350 crankset pictured above is fitted with a 44 tooth chainring. The Jaroon also supports a double chainring configuration.

Beautifully machined dropouts and 142 x 12mm thru axle.
Another view of those stunningly clean welds.
Rack and fender mounts come standard on the Wilier Jaroon.
The Wilier Jaroon can fit 700c x 42mm with tyres between it’s chainstays.
The Jaroon show bike was fitted with Kenda’s 700c x 40mm Happy Medium tyres.
The Wilier Triestina Jaroon spec’d with a SRAM Rival 1×11 build and virtually everything you see on the Interbike show sample is priced at $US 2,550.00.
The Wilier Jaroon is available in four sizes – Small – Medium – Large – X-Large – with top tubes beginning at 52.7mm for the Small and 58.1cm for the X-Large.
We hope to take receipt of a review sample of the Jaroon in the near future. Watch this space…
