Ride Characteristics
The Process 153 feels balanced and responsive. The 64.5° head angle provides modern trail feel without being overly slack. Progressive seat tube angles (76.9° small, 76.6° large) keep climbing efficient across all sizes. The 160/153mm travel ratio favors playfulness over pure gravity handling, making the Process 153 excellent for riders who want to pedal as much as they descend. Aluminum frame keeps cost reasonable while maintaining durability.

Why is the Process called ‘153’?
The ‘153’ refers to the 153mm of rear travel. The Process line includes different models with varying amounts of travel.
How much does the Process 153 weigh?
The aluminum frame keeps weight reasonable at approximately 15kg for most builds, making it competitive with other all-mountain bikes.
What sizes does the Process 153 come in?
Four sizes: S, M, L, and XL. Reach ranges from 430mm (S) to 515mm (XL).
Is the Process 153 good for aggressive riding?
The Process 153 is capable but optimized for all-mountain balance. It excels at converting effort into speed and is excellent for riders who enjoy climbing as much as descending.
Can I adjust BB drop on the Process 153?
BB drop is size-specific (20mm S/M, 30mm L/XL) and is not adjustable. Smaller frames have less aggressive BB drop for better ground clearance.
