Bolder

The bolder is a wheel created by our engineers to meet the needs of a new and rapidly growing sector: e-bikes.

• Available: 29 or 27.5
• Spokes: 32-32
• Internal channel: 33mm
• Brake Disc: 6 Holes
• Front weight 970 (27.5)
• Rear weight 1070 (27.5)

The world of electric mountain bikes is rapidly evolving and the needs are often different from those of normal muscle bikes, with the Bolder we wanted to study a wheel that best adapts to these bikes, characterized by a greater weight and a higher energy.

The bolder is available in 27.5 and 29 diameters, with the option of requesting a 29" rim at the front and 27.5" at the rear, as has now become the trend in many top-of-the-range e-bikes.
The reinforced rim and 33 mm internal channel allow it to accommodate tyres with widths ranging from 2.5 up to the most commonly used 2.8, without any kind of problem.

The Bolder It is assembled in Italy entirely by hand by our Fir technicians and checked using specialized tools to guarantee maximum performance and reliability.
