Cups are for to fill-up bicycle hydraulic disk brakes with special liquid (similar to cars). Most brake producers use DOT4 / 5.1 fluid or mineral fluid. They are not compatible. If you have to fill-up ("bleed") different disk brakes, you have to use clean cups. I wanted to make custom coded (shape + color) cups for proper type of fluid.

Simple chain stay protector for mountain bicycles. Prevents bouncing chain to hit and damage the chain stay. Calming down the ride on rough surfaces.

Variations of holders to combine the GPS navigation with different devices (LED light, bell, etc.). Standardized GoPro mount.

I wanted to mount an existing mirror to a lower location. With integrated hydraulic brake line clamp/holder to prevent rubbing. Compatible with different mirror diameters. Original (exposed) mount goes to the handlebar and prone to random move.

I had to wait 10 years to fix a broken original yellow lever. New lever is prolonged for easier manipulation.

Dedicated rear mudguard for MTB saddle (Terry Arteria). Needed 2 zip ties to secure this thing. Thickness is 1-1,5 mm = is flexible and secure. Backplate is strong, around 3 mm. Works fine in winter as well. It has mounting holes for a GoPro mount or another device (blinker / led light, radar, etc.). Print support distance should be properly calibrated. Standard support structure will brake the thin mudguard flap. Tree support is a way to go.

Eliminates fog honk like noise during braking on demanding trails. The unwanted vibration is generated by old style brake caliper mount and travels on brake line. Rear triangle (FS bike) amplifies the noise as well. Injected cement to the seat stay helps re-calibrate native frequency of the rear triangle.   

Helps to hide the exposed part of bicycle tire valve. Keeps color scheme tidy.

Simple bottle holder of a 1,5 - 2,0 l bottle to the VW group car center console. It has pins to inhibit bottle slip during opening. Sponge bottom.

Fixing broken original blade protector of a hand pruner / secateurs (Florabest).
