Premium, honest performance without the corporate premium. Developing unique carbon fiber molds costs millions — a tax major brands force riders to pay. Cross Bike Co bypasses this by partnering directly with elite overseas factories to source structurally proven, high-performance open-mold frames (including Carbonda and Tideace partner platforms), redirecting those savings into curated lightweight components, precision local assembly and custom paint finishes.

Every single bike is built entirely to order in the North Carolina Triangle area. Cross manages strict material intake quality control, lays down custom finishes, and hand-assembles every pivot, bearing and cable routing pathway from raw frameset to finished turnkey build.

Rather than funding proprietary molds, Cross Bike Co selects established open-mold carbon platforms from premier overseas engineering factories. The company does not own or operate those factories — it selects the chassis, verifies it on intake, and invests the saved margin in components, finishing and local assembly.

The lineage is structured around riding disciplines. The Phosphate gravel series uses Tideace carbon frames with integrated internal storage, optimised for long-distance gravel, fire road speed and adventure versatility in drop-bar or flat-bar builds. The Contour trail series pairs a plush 4-bar linkage with an aggressive, slack headtube for descending stability and confidence on technical singletrack. The Iso hardtail keeps maintenance low and power transfer absolute for fast rolling cross-country singletrack. The Summit downcountry full suspension bridges XC climbing speed and trail capability with a highly efficient pedal platform, dropper routing and tire clearance.

The Phosphate is the gravel model: drop-bar or flat-bar carbon chassis with integrated frame storage and 700x50c tires. The Iso is a cross-country hardtail mountain bike built for race-pace singletrack and immediate acceleration.

Both are full suspension. The Summit is tuned for cross-country and downcountry efficiency — a highly efficient pedal platform that flies up hills while retaining trail capability. The Contour is the trail weapon: a plush 4-bar linkage and aggressive, slack headtube angle for high-speed stability and confidence on steep, chunky descents.

Core is built for everyday utility, rugged gravel paths and maximum entry value. RS suits extended trail riding, steep backcountry fire roads and technical terrain. RS 2 targets competitive gravel racing, fast group rides and rolling mixed-surface routes. ONE is for elite performance, tech-forward riders and demanding endurance athletes.

Configurations primarily scale across Small, Medium, Large and Extra Large (S–XL) geometries. Because modern progressive geometry features steep seat tube boxes and longer reach footprints, the frames match modern sizing trends. The Phosphate and Iso listings publish XS (49cm) through XL (58cm) with rider height guidance. Most configurations are built around a highly agile medium-sized frame footprint as the standard design baseline.

The Phosphate is offered in dedicated drop-bar and flat-bar configurations: Flat Bar | LTWOO TX 12 Speed, or Drop Bar | LTWOO Gravel. The drop bar is optimised for aerodynamic efficiency and high-velocity gravel racing; the flat bar brings mountain-bike-inspired control and upright visibility.

Yes. Because frames are sourced in raw matte form, Cross Bike Co offers custom factory spraying for an additional fee — from raw visible carbon layouts to premium chameleons and color-shifts. Exact colourways and pricing are confirmed with the workshop before assembly begins.

Tiers move through drivetrain, wheelset, cockpit and suspension specification. For example, Iso RS runs Shimano Deore 12-speed with a 120mm XFusion fork and 10PLUS carbon wheels, Iso RS 2 moves to LTWOO EGR Flat Bar Gravel MTB Wireless Groupset shifting, and Iso One adds a Manitou Mattoc Pro and KORE carbon crank. Phosphate tiers move from mechanical LTWOO GRT to LTWOO EGR 2nd-Gen electronic with ELITEWHEELS 5-spoke carbon.

For local riders in Raleigh, Durham and the Triangle region, Cross Bike Co offers direct delivery and local pickup options. Delivery arrangements outside the Triangle are confirmed directly with the workshop when your build is placed.

Yes — local pickup and direct delivery are both offered to riders in the Raleigh, Durham and Triangle region.

Every Cross bicycle is backed by a comprehensive 2-year structural warranty on high-modulus carbon and hydroformed aluminum framesets against manufacturing defects.

Third-party components — including Shimano Di2 groupsets, LTWOO electronic drivetrains, Magene power meters and SUPERTEAM wheelsets — are fully covered under their respective manufacturer warranties. Cross Bike Co manages all warranty claims directly for customers to keep replacement parts fast and downtime minimal.
