Kona Hei HeivsProcess 134
Looking for a short-travel Kona that can handle real trails? The Hei Hei G10 is a remarkably versatile machine, blurring the lines between XC and light trail, but if your priority is outright descending prowess and a truly aggressive trail ride, the Process 134 G3 is the clear winner. However, the Hei Hei might surprise you with its comfort on epic days.


Overview
Kona’s Hei Hei and Process 134 both cater to riders who appreciate a capable, fun-loving bike, but they approach the trail from notably different perspectives. The Hei Hei G10, with 120mm of rear travel and a 130mm fork, has evolved significantly from its cross-country racing roots into what reviewers consistently describe as a light-duty trail bike. It's built for comfort and efficiency over long distances, offering a relaxed character that makes it a true all-rounder for a wider remit of trails, as QuarterHP noted. In contrast, the Process 134 G3, featuring 134mm of rear travel and a 140mm fork, leans much harder into aggressive trail riding, often feeling like a shorter-travel enduro machine. It's designed to instill confidence when things get rowdy, even if it sacrifices a touch of the Hei Hei's climbing sprightliness. The Hei Hei's design philosophy centers on maximizing rider enjoyment and minimizing fatigue on varied terrain, making it an excellent choice for bikepacking or long backcountry missions. Its carbon frame focuses on compliance and comfort, with a supportive suspension tune that manages small bumps well without excessive bob. Conversely, the Process 134 is a more robust beast, aiming for stability and outright descending capability on more demanding trails. Both models are rooted in Kona’s heritage of building no-nonsense bicycles, but the Hei Hei delivers its capability with a smoother, more refined touch, while the Process 134 provides a firmer, more direct feel underfoot.
Ride and handling
The Hei Hei G10 serves up a notably relaxed and confidence-inspiring ride, making it a stellar all-rounder. Reviewers praise its supportive Swinger suspension system, which offers excellent small-bump compliance and traction, making technical climbs less of a struggle. NSMB noted the rear wheel "seldom losing traction and staying on the ground for pivotal manoeuvres" on tricky ascents. The 130mm RockShox Pike Ultimate fork is a standout, delivering impressive steering precision and plushness, which helps the front end stay composed even when things get squirrely. This bike encourages an active riding style, feeling lively and responsive, easily getting airborne thanks to its relatively short 435mm chainstays, as Blister observed. While the Hei Hei excels at feeling composed on moderate trails and flatter terrain, it does have a speed limit. When pushing hard through "higher speed technical terrain" or "blasting through a rock garden at 30 km/h," the bike can reach its upper capabilities, requiring a more calculated approach rather than brute force. Its overall ride quality, however, is praised for reducing rider fatigue, making it comfortable for "all-day riding" and extended backcountry trips. The Radavist's John Watson even found it "enhanced my physical abilities" and made him feel "never vanquished" after big days. The Process 134 G3, on the other hand, comes across as a burly, confident trail companion built for aggressive descents. Its linkage-driven single-pivot suspension, shared with Kona's longer-travel bikes, provides a firm, supportive ride that excels on flow trails and jumps. Blisterreview's tester found that after adding volume spacers and tuning the compression, the bike transformed into "a joy to ride on fast, flowing singletrack, and felt utterly wonderful to push and pump through berms and rollers." The slacker 65.5-degree head tube angle inspires significant confidence in challenging terrain, allowing the bike to "hold a line without being so stiff that it feels jarring," according to Blister. This bike simply handles more demanding terrain better than its travel numbers suggest, feeling robust and capable. However, the Process 134's firmness can be a double-edged sword. Pinkbike highlighted that the "suspension noticeably stiffens up under braking," a trait that demands adaptation and careful braking technique to maintain comfort and predictability on rough sections. On bumpy singletrack climbs, its less supple feel means it can be a challenge to keep the rear tire from breaking traction. While Pinkbike found the overall "firm ride feel" less comfortable on extremely rough, sustained descents compared to more supple 120mm bikes, it still delivers on its promise of a playful and capable ride for those who like to charge hard and leverage its stable platform.
Specifications
The spec sheets for these two carbon models, the Hei Hei CR G10 ($6,299) and the Process 134 CR/DL G3 ($4,899), reveal different priorities, especially considering their price disparity. The Hei Hei, despite its higher price point, comes equipped with SRAM's cable-actuated Eagle 90 mechanical Transmission. Reviewers universally praised this for its crisp, quick shifts, even under load, and its lower replacement cost compared to electronic systems. The Hei Hei's suspension package is a clear highlight, featuring a RockShox Pike Ultimate (130mm) fork and a Deluxe Ultimate rear shock, which NSMB lauded as prioritizing "top-end suspension over an upgraded rear derailleur or another wear item." SRAM Motive Bronze 4-piston brakes with 180mm rotors provide consistent, ample stopping power. The Process 134 CR/DL offers a compelling package for its lower price, including a RockShox Pike Ultimate RC2 Charger 3 (140mm) fork and a Super Deluxe Ultimate RCT rear shock. The drivetrain is a SRAM GX Eagle Transmission, an electronic AXS system, which contrasts with the Hei Hei's mechanical setup. While Blisterreview personally disliked the electronic shifting due to its weight, cost, and charging requirements, Pinkbike noted its precision. A significant difference in stopping power comes from the Process 134's SRAM G2 RSC 4-piston brakes paired with larger 200mm rotors front and rear, which Blisterreview found "not really up to the task" for longer descents, suggesting an upgrade might be needed for aggressive riders. Wheelsets for both bikes are WTB KOM Team i30 TCS rims, but they differ in hubs: the Hei Hei uses DT Swiss 370 (18t star ratchet), while the Process 134 CR/DL opts for DT Swiss 350 (faster engagement). However, Blisterreview found the Process 134's WTB rims "noticeably flexy" and prone to "self-destructing" after a few weeks, indicating a potential durability concern. The Hei Hei's Maxxis Dissector EXO TR 29x2.4WT tires are a balanced choice, praised for traction and rolling efficiency. The Process 134 runs a Maxxis Minion DHF 29x2.5WT up front and a Dissector 29x2.4WT (27.5x2.4WT on size S) in the rear, a more aggressive, downhill-oriented combo, though Blister found the lean angles of the DHF and Dissector a bit mismatched. Critically, the Process 134 CR/DL's RockShox Reverb dropper was a consistent point of failure in reviews, developing squish and requiring frequent, often ineffective, venting, a common issue that could lead to early warranty claims. The Hei Hei, in contrast, uses a TranzX Dropper +RAD Internal, which generally performed flawlessly in reviews. These details suggest the Hei Hei, despite its higher price, may offer a more reliable and cohesive component experience out of the box, particularly regarding the dropper and wheels, while the Process 134 presents a solid frame foundation that might benefit from targeted component upgrades for harder riding.

Geometry and fit comparison
Comparing these two Kona models in size Large reveals distinct approaches to geometry, shaping their on-trail feel. The Hei Hei G10 features a 66.0-degree head tube angle and a 75.9-degree seat tube angle, combined with a 474mm reach and 630mm stack. This geometry is decidedly modern for an XC-leaning bike, offering a 1.5-degree slacker head angle than its predecessor. Reviewers described the fit as providing an "aggressive riding stance" for a 5'10" rider, yet the seated pedaling position remains "super comfortable" (NSMB). The 435mm chainstay length across all sizes contributes to a playful feel, allowing the bike to "hook around corners nicely" and maintain agility. The Process 134 G3, by comparison, takes a more aggressive stance, with a slacker 65.5-degree head tube angle and a steeper 76.7-degree seat tube angle. Its reach is longer at 480mm, paired with a slightly lower 625mm stack. This translates to a longer, lower, and slacker setup, which, according to Bike-test, gives "lots of confidence in challenging terrain" and contributes to "smooth handling" in steep sections. The 435mm chainstays are identical to the Hei Hei, but the overall longer wheelbase (1230mm vs. 1223mm) of the Process 134 emphasizes stability at speed. Its 33mm BB drop compared to the Hei Hei's 31mm also gives it a slightly lower center of gravity, enhancing plantedness on descents. These numbers translate directly into rider fit and intended use. The Hei Hei's slightly slacker effective seat tube angle and taller stack (75.9 degrees vs. 76.7 degrees, 630mm vs. 625mm) create a more upright and relaxed climbing position that's ideal for long days in the saddle, but some reviewers found it "too slack on steeper, sustained climbs," necessitating fore-aft saddle adjustments. The Process 134's steeper seat tube angle should, in theory, put the rider in a more efficient position for steep climbs, though Pinkbike's reviewer (on a size S) found it "a little too far off the back for my liking," requiring conscious weight shifts to keep the front wheel down. For taller riders, Pinkbike's Dario DiGiulio also noted the Hei Hei's XL felt a bit "sprawled out" with a low stack, suggesting potential issues with front-end weighting if not balanced with higher-rise bars. Ultimately, the Process 134 is built for a more aggressive, attacking descending style due to its slacker head angle and longer reach, while the Hei Hei balances climbing comfort with capable, playful handling for a broader range of trails.

Who each one is for
Kona Hei Hei
The Kona Hei Hei G10 is the ideal partner for the rider who values comfort and versatility over outright racing speed. If your weekends involve epic backcountry missions with significant climbing and varied singletrack, or if you're looking for a bike that can comfortably tackle multi-day bikepacking trips, this bike is for you. It excels at making long distances less fatiguing, allowing you to ride for hours without feeling beaten up. This bike also suits those who appreciate a playful ride on blue and black trails, enjoying pumping rollers and finding flow without needing an enduro sled's travel. It's a great choice for riders who want a capable full-suspension bike that feels light and efficient but can still handle rougher descents with confidence, even if they aren't blasting through rock gardens at top speed.
Kona Process 134
The Kona Process 134 G3 is perfectly suited for the aggressive trail rider who craves downhill confidence and a playful character without stepping up to a full-blown enduro bike. If you spend your time sessioning jumps, railing berms on flow trails, and tackling demanding descents, this bike delivers. It's for the rider who wants a bike that punches above its travel class on descents and rewards an active, precise riding style. While it can climb, it's not a featherweight race machine, so it suits those who prioritize the fun on the way down and are okay with a slightly less spritely feel on the ups. This is also a solid option for riders on a budget who want maximum trail capability and a robust frame, and are prepared to potentially upgrade certain components like brakes or the dropper post down the line.
