The Wabi Prism frameset is our most versatile take on the simple machine. It keeps the lightweight, responsive character of our track-inspired bikes while adding clearance for tires up to 38mm, a full array of frame and fork eyelets, greater standover clearance, and a straight chromoly fork for added stiffness and a more direct feel. The result is a Wabi with more capability for rough city streets, longer rides, crushed gravel, and plenty in between. WHY WABI Lightweight Steel Construction. The Prism uses heat-treated, double-butted Reynolds 725 chromoly steel to achieve a ride that’s both lively and surprisingly light for a steel frame. The oversized tubes are TIG-welded with clean, minimal lines that keep the frame responsive, comfortable, and quick on everything from relaxed spins to longer rides. Artisan Craft & Finish. Every frame is hand-built by skilled artisans with roots in Japanese frame-building traditions. You can see it in the alignment, the smooth welds, and the overall finish. The frame gets a traditional wet-paint job followed by a clear coat, giving each color a deep, polished look. All-Ride Geometry. The Prism is balanced for just about anything. Its geometry offers long-distance comfort while still feeling quick and confident through city streets and tight corners. It stays smooth, predictable, and easy to trust wherever you take it. Precision Steel Fork. Performance Headset. The straight chromoly fork is brazed for strength and feel, with an investment-cast crown and forged fork ends for solid handling. It uses a 1 1/8" steerer for modern stiffness and comes with our Wabi Pro headset, made by FSA using their well-regarded Orbit-X design with sealed cartridge bearings. Small Details for Real Use. Extra-long forged track dropouts make wheel placement easy, and the integrated seatpost collar keeps the frame looking clean and classic. The frame also includes mounts for two bottle cages along with an array of eyelets and bosses for racks and fenders. Colors and Customization. The current colors are Haze Grey, a solid, dark, ashy gray; Oleo Yellow, a solid, buttery yellow; and Aura Purple, a limited-edition, sparkly purple. There will be no custom colors offered at this time. TECH SPECS AND NOTES Includes: Frame, fork, complete headset, seat post clamp, and bottle bolts. Weight (55cm): 5.6 lbs (weight does not include headset or bolts) Accepts 68mm English threaded bottom brackets. Threadless 1-1/8" steel steerer tube. Note: The steerer tube length is pre-cut to match your frame size, allowing 35-40mm of spacers between the headset and stem. Wabi Pro headset included along with spacers, top cap, and installed star nut. 100m front dropout spacing; 120mm rear dropout spacing 27.2mm seatpost compatible. Front and rear recessed caliper brake bolt mounts for mid-reach brakes. Note: Standard short-reach brakes will not work with this frame. Ideal tire size clearance is 35mm, but can accept most 38mm tires. Accommodates almost all track cranksets (tested up to 135mm Q-factor). Note: The drive-side chainstay has a dimple to ensure crankarm-spider and chainring clearance. Eyelets and bosses at rear dropout, seat stay, front fork dropout, and fork. No cable stops on frames. We recommend cable clips for a rear brake install. Bottom bracket is not included. If you plan to convert this frame to 650B, we recommend 46-47mm tires and 165mm crank arms to reduce any pedal strike risk. For brakes, only Dia-Compe BRS202s will provide the proper reach front and back. SIZING We highly recommend reviewing our sizing guide before making a purchase. We recommend looking at both your height and your actual inseam/standover height. IMPORTANT: Prism uses a center-to-top measurement, from the center of the bottom bracket to the top of the seat tube. Our other models use a center-to-center measurement. Because of this, the size numbers aren't directly comparable. A 51cm Prism is equivalent in size to a 49cm in our other models, a 54cm Prism to a 52cm, and so on. Rider Height Frame Size* Standover Height(35C Tires) 5'0" - 5'4" 47 CM 28.7 IN 5'4" - 5'7" 51 CM 29.3 IN 5'7" - 5'10" 54 CM 30.5 IN 5'10" - 6'1" 57 CM 31.5 IN 6'1" - 6'3" 60 CM 32.6 IN 6'3" - 6'6" 62 CM 33.4 IN IMPORTANT: The Prism is measured center-to-top, which is different than our other models (Classic, Special, Lightning and Thunder), which are measured center-to-center. You can also find a complete geometry chart on our tech/geometry page. COMPONENT SIZING The Prism is designed around a 170mm crankarm, a 24mm setback seatpost, and stem lengths that change with frame size and rider height. You can find our recommendations under 'Determining Bike Components Fit on the sizing page. Using different parts may change the fit. IMPORTANT NOTE ON COMPATIBILITY We can only guarantee compatibility with the parts used on our complete bikes. If you’re planning a custom build, feel free to reach out—we’re happy to share anything we know—but we can’t offer refunds for issues with third-party components.
