A New Ti King Is Crowned: Inside the Ultra-Light Litespeed Coll Dels Reis

For decades, titanium bikes have been prized for their legendary ride feel, effortless durability, and timeless aesthetic. Litespeed—long recognized as a leader in titanium frame innovation—has taken things to an entirely new level with the Coll Dels Reis. Boasting a claimed frame weight as low as 948 grams (in a size medium with select configurations), this sub-1,000-gram disc-brake titanium road bike challenges the weight barriers traditionally dominated by carbon. Even more impressive, it does so while maintaining the hallmark smoothness of titanium and offering an 85 kg (187 lb) rider weight limit. This is, by all accounts, the new “World’s Lightest Titanium Road Bike.”

Taking Over the Ti Throne

Previously, the Litespeed Spezia carried the title of “World’s Lightest” titanium road frame at 1,145 grams. Today, the Coll Dels Reis knocks its stablemate off the top step, coming in around 197 grams lighter and setting a new standard for ultra-light titanium builds. In fact, Litespeed’s engineers claim the Coll Dels Reis is some 232 grams lighter than the next-closest competition in the titanium disc-brake category—a gap that underscores just how radical this new frame really is.

“How, how?”
–As the famous Glesga Nature gals might say, Litespeed’s response is simple: strict rider weight limits and uncompromising engineering.

Innovative Materials & Manufacturing

The Coll Dels Reis is crafted from aerospace-grade 3AL/2.5V titanium, meticulously cold-worked to achieve optimal butting and shaping in each size. Litespeed’s proprietary manufacturing methods—refined through years of research and even NASA collaborations—allow for advanced tube manipulation that few other makers can match. This includes custom thicknesses along the tube’s length (to reinforce high-stress zones) and precision machining to shave unnecessary grams everywhere else.

• Frame Weight: 948 g (size medium, BSA bottom bracket, Ti SL dropout)
• Rider Weight Limit: 85 kg (187 lbs)
• Size Range: XS–XL (6 total sizes)
• Lifetime Warranty: True to Litespeed’s heritage, the frame is backed for life.

Though the frame is best known for its minimal weight, it’s important to note that every titanium tube is engineered to maintain structural integrity, stiffness under load, and the comfort titanium is famous for.

Modern Performance Features

1. T47i or BSA Bottom Bracket
Out of the box, the Coll Dels Reis arrives with a T47i threaded bottom bracket. Known for its wide stance and reliability, T47i offers reduced bearing friction with easy serviceability. For those chasing every last gram, Litespeed offers an optional BSA Superlight system that shaves an additional 59 grams from the total weight.

2. Universal Derailleur Hanger (UDH)
Modern drivetrains evolve quickly, and universal derailleur hangers help future-proof your investment. Weighing just 35 grams, the UDH enhances compatibility while keeping the overall frame weight low.

3. Internal Cable Routing
Fully internal cable routing protects cables from road grime, delivering a sleek look and potentially longer component life. Litespeed pairs this design with an ENVE Road IN-Route fork and Chris King AeroSet headset for a refined, integrated front end.

4. 35 mm Tire Clearance
Traditional climbing bikes often limit tire size, but the Coll Dels Reis offers clearance up to 35 mm—making it more versatile for riders who want extra cushioning on rough roads or the occasional unpaved detour.

5. Disc Brakes & Thru-Axles
Even featherweight climbing bikes need reliable stopping power. This Litespeed disc-brake design utilizes 12x100 mm and 12x142 mm thru-axles, ensuring you can handle steep descents with maximum control.

Rider Weight Limit & Real-World Considerations

To achieve a sub-1,000 gram titanium frame, some compromises are inevitable—one being the recommended 85 kg (187 lb) rider weight limit. That may exclude some potential buyers who appreciate titanium’s storied ride quality but exceed that threshold. Still, for dedicated climbers who fit the profile, Litespeed offers a lifetime warranty that testifies to the brand’s confidence in its design and manufacturing quality.

A Climber’s Geometry with Big Ambitions

Drawing inspiration from Mallorca’s legendary Coll del Reis climb—steep switchbacks, scenic overlooks, and relentless gradients—the bike’s geometry emphasizes responsiveness on uphill attacks and stability during fast descents. The fairly aggressive angles and shorter rear end encourage out-of-saddle surges, while the 35 mm tire clearance lets you stay agile on broken pavement. Whether you’re a KOM-chaser seeking the perfect climbing rig or a rider who wants a nimble racer for mountainous fondos, the Coll Dels Reis is engineered to excel in the high peaks.

Why Titanium Instead of Carbon?

It’s no secret that carbon fiber can drop below 800 grams for a road frame, and certain boutique models weigh even less. However, the Coll Dels Reis caters to cyclists who value titanium’s distinctive traits:

• Durability: Titanium is famously resistant to corrosion and fatigue.
• Ride Quality: The frame’s damping characteristics often make rough roads feel smoother.
• Longevity: The frame can stand up to years of hard riding without succumbing to material degradation.

“On descents, the faster I go, the more stable and confidence-inspiring it feels.”

For riders who prioritize reliability, comfort, and a timeless aesthetic, the Coll Dels Reis delivers a high-end climbing experience in a material that stands apart from mass-market carbon.

Pricing & Availability

• Frame-Only Price: $6,499 (USD)
• Complete Bike: $16,500 (USD)
• Warranty: Lifetime, underscoring Litespeed’s commitment to quality.

Litespeed offers six sizes (XS to XL) and customization options like dropout choice (standard vs. Ti SL) and bottom bracket type (T47i vs. BSA Superlight). The frame officially weighs 1,049 grams when configured with T47i, the universal derailleur hanger, and a welded titanium head badge—but can drop to 948 grams through weight-conscious upgrades.

Final Thoughts

The Litespeed Coll Dels Reis is a bold statement in the titanium bike market, pushing the boundaries of what’s achievable with an already revered material. If you’re under the 85 kg threshold, value the smooth ride of Ti, and want a bike that stands out in a sea of carbon, this new release from Litespeed might just be your dream climbing companion. From the local KOM chase to all-day alpine epics, the Coll Dels Reis proves that ultra-light doesn’t have to mean sacrificing the unique resilience and feel that only titanium can deliver.
