PRESS RELEASE

Introducing the New Rocky Mountain Thunderbolt

Words Rocky Mountain Bicycles
Date Mar 27, 2018

First introduced in 2014, Rocky Mountain Bikes' Thunderbolt carves a line between a pure-bred XC whippet and a longer-legged trail bike. We've reviewed both the OG version as well as back-to-back look at one equipped with Shimano's Di2 Groupset. Now they've updated the whole carbon lineup with a number of features first seen elsewhere on Rocky's bikes. Read on after the break to get all the details, including pricing in both CAD and USD


We are very excited to let you know that the new Rocky Mountain Thunderbolt is launching on March 27! 


With the Thunderbolt we’ve designed an all-new carbon frame that pushes the rear travel to 130mm, increases stiffness, lowers the rate curve slightly, and gives the frame a host of next-generation features—but keeps its playful geometry and wide range of RIDE-9™ adjustments. The Thunderbolt is at home on technical climbs, powering through rough stuff, and popping off every trail feature you lay eyes on.

Thunderbolt Carbon 90 BC Edition

With a long stroke shock that provides 140mm of rear travel, we’ve kitted out the Thunderbolt BC Edition with wide bars, big tires, ultra-stiff wheels, and more capable suspension. With a wide range of RIDE-9™ adjustments for whatever terrain you want to tackle, its more aggressive nature is perfect for all-day trail adventures.

Improved suspension performance

We’ve flattened out the rate curve to directly increase the amount of usable travel, while maintaining mid-stroke support and making small-bump performance even more sensitive. Higher anti-squat values dramatically improve pedalling efficiency.

Next generation features

Comprehensive evolutionary updates across the platform include features like tooled axles, single-sided bearing pivots, integrated “Spirit Guide” chainguide, 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 slightly lengthened the chainstays to improve climbing traction and used a moderately steep seat tube for further climbing performance.

Technical Details:

• Increased anti-squat for better pedalling efficiency.
• Size Specific Tune ensures that riders of all sizes get the appropriate rear shock tune. Our design team creates custom shock tunes base on field testing feedback, and adjust the tune of each shock for specific frame sizes.
• 27.5 Wide Trail and 26+ compatible.
• Max tire clearance is 27.5 x 2.5 and 26 x 2.8 (3.0 with low profile knobs).
• Bearings at all pivots, including at the lower shock mount (still compatible with aftermarket shocks).
• Blind pivots maximize rider heel clearance at the chainstay.
• Lighter, tooled rear axle, with an updated axle nut for a more intuitive assembly.
• Improved cable management including large head tube and down tube access ports, full-length shift housing, and internally routed shift housing and brake lines the front triangle housing.
• 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.
• Integrated “Spirit Guide” chainguide, with 2-bolt ISCG05.
• BC Edition uses a longer stroke shock to yield 140mm of travel.
• 1x optimized design with wider main pivot.
• Lower standover height.
• Significantly stiffer thanks to one-piece seat stays, new envelope, and updated layup.
• Modern parts compatibility (boost spacing, metric shock lengths, post-mount 180mm brakes, etc.).
• All sizes fit a water bottle in the front triangle with any reservoir shock currently on the market.
• Sizes: XS-XL
