The Siena
WANT TO KNOW MORE?
With its cobblestone streets giving way to legendary white gravel roads, the medieval city of Siena has captured the imagination of cyclists worldwide. Each March, the cycling world turns its attention to this UNESCO World Heritage site as riders thunder across the region’s iconic strade bianche.
The strade bianche are those chalky light gravel roads that wind through rolling hills dotted with cypress trees and ancient farmhouses, before culminating in the breathtaking finale at Siena’s shell-shaped city square.
Siena represents the essence of cycling versatility: perfectly paved roads seamlessly transition to gentle dirt paths and light gravel sections, demanding a bicycle that can dance gracefully across mixed surfaces without compromise.
This is exactly the spirit we sought to capture when creating a frame that honors both the timeless beauty of Italian steel craftsmanship and the modern cyclist’s desire for true versatility. In Siena, as in cycling, the most memorable journeys happen when you’re free to follow whatever path calls to you – whether it leads across perfectly paved hilltop roads or down scenic off-road paths that promise adventure around every bend.
The Siena
Traditional craftsmanship meets modern versatility
The Siena represents a perfect marriage of time-honored Italian framebuilding techniques and contemporary cycling demands. Built one at a time using traditional fillet-brazing methods in our Marostica workshop, each Siena showcases the purest form of the skills that have defined Italian framebuilding for generations. Yet beneath this classic craftsmanship lies thoroughly modern thinking: the Universal Derailleur Hanger (UDH) standard ensures reliability and ease of maintenance. Combined with generous clearance for up to 700c x 35mm tires, the Siena transforms effortlessly from a classic road machine to an all-road explorer, ready to tackle the varied terrain that defines the Italian landscape.
Your custom-finished frameset
Each Siena is custom-finished to reflect your personal style, with five carefully selected solid color options available. For those seeking the legendary finish that has made Officina Battaglin frames instantly recognizable worldwide, an upgrade unlocks access to our coveted cromovelato process with 13 stunning translucent options.
Ordering process and pricing
The Siena is produced in small batches to ensure the highest quality and attention to detail. The first step in creating your custom-painted bike is reserving a frame, which will be custom-painted to your exact specifications in our Italian workshop. Once you’ve decided on your favorite color, thanks to our in-house painting production process, your custom Siena will be ready for delivery in just 4 weeks. Each frameset includes the frame finished in your favorite color, a matching carbon fork, headparts, and front and rear thru-axles.

Framesets with solid paint finishes start at €2.100 (£1.818 | USD $2.459)*, with the Cromovelato’s options available through a €1,500 upgrade.
