A closer look at the model

The bike in detail.

Procaliber 8 is a fast and high performance country crosstail, designed to track personal records on singletrack as well as to line up on the starting line. The Alpha Platinum aluminium frame guarantees maximum handling in narrow curves and uneven sections, while the RockShox Recon Gold 120mm fork smoothes any roughness. The SRAM Eagle transmission at 12 speed with a wide range of ratios, the light wheels Bontrager Kovee and the hydraulic disc brakes Shimano complete the equipment of this model ready to go ol

A better way to produce aluminum - Starting from 2024, we started replacing traditional aluminium with reduced carbon footprint aluminum, produced with renewable energy. By October 2025, almost all the aluminum bikes produced, including this one, have made the transition, significantly reducing our environmental footprint.

Questions before you ride?

How do I check availability in my size?
The size table distinguishes in-stock items, online orders and sold-out items. For sizes available on request, use the contacts in that row to confirm availability and lead times with our team. Only variants available for online purchase can be added to your basket.
Can I test a bike before deciding?
The Doctorbike Bike Test is available by category, rather than for every individual model. Our team will confirm the category, size and test availability with you.
Can I get help with size and riding position?
Yes. Talk to our team and explore bike fitting with Velosystem® technology, with dedicated measurements and adjustments.
Who should I contact for servicing?
Contact our certified workshop in Magenta. Arrange the work and an appointment with us: our service continues after purchase.
