Included will be a 5mm, 10mm, and 15mm spacer. \u003c\/p\u003e\n\u003cp\u003eFrame Not Listed:\u003cbr\u003eIf your frame isn't listed above, don't hesitate to reach out. As long as the top cap can be easily found, there's a good chance an adapter can be developed. Send a message with your frame make, model, and model year along with the cockpit or stem you're looking to run and I'll let you know what's possible. For Trek and\/or Specialized owners, Trek and Specialized have done a good job creating as many different proprietary top caps for every possible kind of handlebar or stem that the respective manufacturers make. For this reason, if you want to run a different handlebar or stem that is not from Trek or Specialized, please have the part number of the respective top cap or spacer that your bike uses to make it easier to source. \u003c\/p\u003e\n\u003cp\u003eColor Options: \u003cbr\u003eAll adapters are available in black as standard. White is available per request. If you're looking to match your frame's livery or paint scheme, feel free to reach out with your color request. Custom colors are possible depending on material availability, please reach out about this BEFORE placing your order — filament options do vary, so I'll confirm availability before you purchase. No guarantees on specific colors outside of black and white, but I'm happy to check.\u003c\/p\u003e\n\u003cp\u003eDesign Rationale — Why an Adapter Spacer, Not a Replacement Top Cap: \u003cbr\u003eThe decision to design these as spacer adapters rather than full replacement top caps comes down to two things: tolerance risk and convenience.\u003cbr\u003eBearing preload between the top cap and headset bearings is a tight-tolerance interface. Replicating that as a printed part introduces unnecessary variables I wasn't willing to accept. More practically, it means you don't need to replace your existing stem spacers — your OEM stack stays as-is. The adapter sits as the final spacer in the stack, directly interfacing with the integrated cockpit or stem.\u003c\/p\u003e\n\u003cp\u003eOn Stack Height: \u003cbr\u003eThese adapters have been designed to minimize added stack height as much as possible. The limiting factor isn't material thickness or design — it's hydraulic hose routing. Different frames and cockpits exit their hydraulic lines in different locations, and the adapter needs enough internal clearance for the hose to travel without a sharp bend.\u003cbr\u003eA good reference point: ENVE's own V5Rs top cap runs approximately 15mm of stack height even with a fully slammed position for exactly this reason. Most of these adapters come in at around 10mm, and most OEM top caps are around 5-10mm in stack. Adapters where the hydraulic exit points on the frame and cockpit are closely aligned will run even less.\u003c\/p\u003e\n\u003cp\u003eThe added stack versus a native top cap will typically be in the 5–10mm range. Given that modern bike fitting trends are increasingly moving toward higher stack and longer reach, this is unlikely to meaningfully affect your position and will probably improve your position — and it certainly won't cost anyone a race.\u003c\/p\u003e","brand":"Oosta3D","offers":[{"title":"Colnago V4rs\/C68 \/ Enve In-Route \/
