The New Rocky Mountain Altitude

[ad3]

Rocky Mountain just released the long due, updated version of the Altitude. With 150mm travel out back it isn’t quite as rowdy as the Slayer and while it also uses their “Ride-9” adjustable suspension/geo and hidden pivots, it features a different suspension layout.

Press Release:

Overview

Intended Use: Aggressive Trail
Wheel Size: 27.5 Wide Trail
Front Travel: 160mm
Rear Travel: 150mm

Details

Increased anti-squat for better pedaling efficiency
27.5” Wide Trail and 26+ compatible
Bearings at all pivots, including at lower shock mount (compatible with aftermarket shocks as well)
Blind pivots maximize heel clearance
Lighter, tooled rear axle
Improved cable management: large headtube ports, full shift housing, large downtube access port, and internal shift and brake housing within the front triangle
Future-proofed to be compatible with Di2, Fox Live, and a dropper post simultaneously
Seat-tube lengths have been adjusted to accommodate longer dropper posts at maximum insertion.
Chainstay and downtube protectors. *Due to production delays, the initial shipment of 2018 Altitudes will not include downtube protectors. They will be shipped to shops as soon as they’re ready.
Integrated “Spirit Guide” chainguide, with 2-bolt ISCG05
1x only
Lower standover height
Significantly stiffer thanks to one-piece seatstay, new envelope, and updated layup (25% more lateral stiffness)
Modern parts compatibility (boost spacing, metric shock lengths, post-mount 180mm brakes, etc.)
All sizes fit a water bottle in front triangle, even with a reservoir shock
Sizes: XS-XL
Weight:
- Frame & shock: 5.45lb (2470g), size Medium

Improved suspension performance

We’ve increased overall progression and support at sag, while making small-bump performance even more sensitive. Higher anti-squat values dramatically improve pedaling efficiency.

Next generation features

Comprehensive evolutionary updates across the platform include features like tooled axles, single-sided bearing pivots, integrated “spirit guide” chainguide, boost spacing, and metric shock compatibility.

Updated Ride-9™

Our Ride-9™ system provides a wide range of geometry and suspension adjustability; it has been moved into the link for lighter, narrower packaging.

Progressive geometry

To add control and descending capability, we’ve increased reach, slackened the headtube angle, and lowered the bottom bracket. We’ve retained short chainstays to keep the bike agile, and used a moderately steep seattube for efficient climbing performance.
