Bike mounts · designed for your post, cockpit and device · shipped worldwide

The mount your bike didn't come with

A Garmin Varia on a D-shaped seatpost. An Edge 1040 on an integrated aero bar. A 250 g lamp that slips in its rubber-band bracket. We design the mount for your exact bike and device, 3D print it in ASA or carbon nylon, add metal inserts and stainless bolts, and ship it worldwide from Warsaw.

Renders of three orange printed bike mounts: an out-front computer arm with Garmin and GoPro mounts, a seatpost radar clamp, and a lamp cradle.

The problem

Aero bikes have nowhere to clamp

Mounts are made for round tubes. Modern bikes have D-shaped seatposts, flat integrated bars and saddles with their own accessory holes. The factory mount exists only for current models, if at all. We researched 229 fit problems cyclists posted on forums and in shop reviews. The same three come up again and again: a radar or light that rotates on a shaped post, a computer with no place on an aero cockpit, and a heavy front lamp that sags. Each needs one small part that follows your bike's shape and bolts to metal that's already there.

Examples

Three example designs

Designed from typical requests, not delivered orders. In the renders, orange is printed, metal and blue are bought parts, grey is your bike.

Example design · seatpost or saddle

A Garmin Varia that stays put on an aero seatpost

Problem: The band mount in the box is made for a round post. On a D-shaped or aero post it twists sideways, slides down, or sits at the wrong angle. Owners of a Specialized Venge or SL7, a Trek with a Blendr post, a Canyon SP0077, a Basso Palta or a Sensa shaped post wrote the same thing. A saddle bag often takes the only spot left.
We checked: Which posts have a factory mount and for which models. Where the radar needs to sit so the beam clears a bag. How aluminium exact-fit mounts and printed mounts from small makers attach to the post or the saddle rails.
Idea: Two variants of one design. A contour clamp shaped to your post's profile, with a TPU pad against the paint, closed by a stainless bolt into a brass insert. Or a plate that fixes to the saddle rails or the saddle's own accessory holes, such as Specialized SWAT or Bontrager Blendr, and puts the radar behind the bag.
Fit: The post profile is traced from your photo or a paper outline. A standard Garmin quarter-turn insert takes the radar; Trek Flare and Magicshine lights get their own interface. The angle is fixed in the design, not by a rubber band. Max device weight and a tether loop are part of the part.
Rough price: from ~€29 · about 30–60 g of ASA or PA-CF · a universal band mount costs €9–15 and doesn't fit

Example design · integrated cockpit

A computer mount for a bar with no round section

Problem: Integrated aero bars have nothing for a clamp to grip. Canyon CP0018 and CP0045 cockpits, Syncros bars on a Scott Addict, a Zipp SL-80, a Most Talon on a Pinarello: each has its own faceplate bolt spacing and a different underside. Universal out-front mounts tilt or hit the bar. Factory mounts rarely have a place for a light or camera. One rider searched two months for a mount for a Garmin Edge 1050 on a Syncros bar.
We checked: The bolt spacing and faceplate geometry of the cockpit from spec sheets and photos. Which computer, which quarter-turn or Wahoo puck. Which lamp or camera goes underneath and how heavy it is.
Idea: A printed arm that bolts on with the faceplate bolts, replaced by stainless bolts of the right length. Steel sleeves in the arm carry the bolt load, so it goes through metal, never through plastic. The faceplate itself stays original. On top a standard Garmin quarter-turn insert at the angle you choose. Underneath a GoPro three-prong interface for a light or camera.
Fit: The arm follows the bar's top and underside so it doesn't rock. Printed in carbon-filled nylon, layers along the load, metal inserts, no printed threads. The faceplate bolts are torqued to the bike maker's spec, given in the fitting notes.
Rough price: ~€59 · about 50–90 g of PA-CF plus inserts · a round-bar out-front mount costs €20–30 and doesn't clamp here · exact-fit aluminium mounts cost €55–83

Example design · front lamp

A 250 g lamp that doesn't sag

Problem: Bright lamps are heavy. A Busch+Müller Ixon Space weighs about 250 g; a Magicshine Hori 1300 or Cateye GVolt 70.1 isn't far behind. Rubber-band and hanging adapters slip on rough roads and the beam drops to the front wheel. Supplied clamps often don't take a 35 mm bar.
We checked: The lamp's bracket and bolt pattern. Your bar diameter and where a metal clamp already sits or can sit. Where the beam has to point with a computer above it.
Idea: A cradle that matches the lamp's bolt pattern, screwed to an existing metal clamp or a GoPro adapter under the bar. A TPU pad grips the lamp and damps vibration. The beam angle is set once and held by a bolt, not by friction.
Fit: We reuse your metal bar clamp. We never print a clamp around a carbon bar. ASA or PA-CF, brass inserts, stainless bolts, threadlocker, declared max weight.
Rough price: ~€29 · about 30–50 g of PA-CF or ASA with a TPU pad · a universal bracket costs €8–15 and slips

Small parts

Lost a cap nobody sells?

A Sigma BC 14.16 battery cap is lost, and the only fix on offer is a whole new sensor. The battery-bay cover for a Riese & Müller Charger 4 costs over €50, if it's available. We make non-structural caps, covers and accessory plates from a photo and a few measurements, and keep the file so a second one is a reorder. From ~€19.

Materials and safety

Materials and what we won't make

Bike parts live outdoors, in sun and vibration. We print them in ASA, which holds up to about 95–100 °C and resists UV, or in carbon-filled nylon for stiff arms. Never PLA: it softens at 55–60 °C and creeps. Threads are brass inserts, bolts are stainless, and we never print a thread.

We only make device mounts and non-structural caps and covers. Every mount fixes to a metal clamp or bolt hole that's already on your bike, carries a declared max device weight, and comes with a tether loop and fitting notes: torque, inspect before each ride, replace after a crash. It's a mount, not a safety device.

We won't make

Brakes, levers, rotors, pad or hose adapters, anything in the brake heat zone
Stems, headset spacers, handlebars, bar clamps, seatposts, seatpost clamps, saddle rails
Derailleur hangers, axle adapters, torque arms, motor or battery mounts
Racks, child seats, trailer hitches, kickstand mounts, anything that carries a person or a load
A printed clamp on a carbon bar or steerer; no drilling or tapping frames or forks
Copies of patented mounts for resale

Pricing

Rough prices

Same rule as everything we make: roughly 2–3× a mass-produced part that would fit, if one existed. The honest comparison is the universal mount that doesn't fit. For reference, custom-printed mounts from small makers go for about €30 (140 zł), and exact-fit aluminium mounts for €55–83. Taxes included, delivery separate, fixed price before we start.

Part	Universal part, if it fits	Made for your bike
Rear radar or light mount, aero post or saddle rails	€9–15	from ~€29
Computer mount for an integrated cockpit, GoPro underneath	€20–30	~€59
Under-bar mount for a heavy lamp	€8–15	~€29
Lost cap or cover	€50+, or not sold	from ~€19

FAQ

Bike mount questions

Will the mount hold a Garmin Varia on rough roads?

That's what it's for. The contour spreads the load over the post, a bolt in a brass insert takes the torque, and the angle is fixed in the design. Vibration, not weight, is what breaks mounts, so we orient layers along the load, use thick walls and dense infill, and state a max device weight. Each mount has a tether loop.

Can you make a mount for my Canyon or Scott cockpit?

Yes, for the models we can look up or you can photograph: Canyon CP0018, CP0045 and CP0030, Syncros bars on Scott, Zipp SL-80, Most Talon and others. Send the bar or cockpit model and a photo of the faceplate with a ruler. If we can't confirm the bolt spacing, we mark it red for you to measure.

Is a 3D-printed mount safe on a carbon bike?

Our mounts fix to metal that's already there: your bar clamp or the faceplate bolts. On the faceplate, steel sleeves carry the bolt load, so it never goes through plastic, and the original faceplate is torqued to the bike maker's spec, given in the fitting notes. We never print a clamp around a carbon bar or steerer, and we never drill.

Why not PLA or PETG?

PLA softens at 55–60 °C and a black part in the sun gets there. PETG loses strength after years outdoors. Bike parts get ASA, or carbon-filled nylon where they need to be stiff.

Can you make a derailleur hanger, a spacer or a rack mount?

No. Those carry load or sit in the steering or drivetrain, and a failure puts a part into the wheel. We make device mounts and non-structural caps only. See what we won't make.

What if it doesn't fit?

Same promise as everything we make: if the mount doesn't fit the post, cockpit or device we agreed on, send a photo and choose a full refund or an improved version free. If the cause was a measurement you gave us, the new part costs production only.

Have a mount that almost fits?

Send a photo of your bike and your device. We'll tell you honestly whether we can make it, and if a shop already sells it.
