Making my own way

If I look back, I remember myself always inventing things and looking how to solve problems.

I believe beauty and quality are the result of a deep search on functionality and sustainability.

I detest luxury and decorations.

I think superlatives come from vanity.

I always prefer the raw look of something real, rather than the perfect finish of something fake.

In my career as an entrepreneur, I have found that success is not democratic, and that money, when it comes, comes with devils. So, after a decade of dealing with success and failures, I’ve learned that there’s only a way to build a solid and successful company: walk the hard way on my own, patiently, being very conscious of my limitations and measure each of my steps.

After 4 years of this realization, I can begin to say that it was the right way.

Below there are some of the projects that have help me to found my way:

Studio Musko, time to explore...

Circa 2016, before founding Camperlove, and after a decade of entrepreneurship drama, I founded Studio Musko, a playground to explore and find a new way.

Ritchey Dropper Post

Ritchey Logic asked me to design a light and reliable dropper post at a reasonable price.

It was not an easy job to achieve Ritchey’s standards, it were 2 years of intensive work with many comings and goings to Taiwan, but finally the co-work with Tom resulted in a solid and reliable pneumatic/mechanical 3 positions dropper post, that passed ISO requirements with excellence.

It weighs 445g (125mm travel version, w/o remote lever)

The remote lever is compatible with Sram MatchMaker and Shimano I-SPEC 2 systems.

Blacx Jewel 2012 Dropper Post

On the Blacx Jewel 3rd generation my main priority has been to make a very solid product, capable of working under extreme conditions, crash-proof and not easy to be damaged in case of abuse.

Oversized bolts and thick tube walls were used, but thanks to the easy implementation of a pneumatic cylinder in the MCL system, the result was a very light adjustable seatpost.

On the handlebar, the lever has been replaced by a simple button. It can be positioned at convenience, facing up or downwards, close to the grip and it can be operated with a small thumb movement.

The previous models had a very neat cable routing to main tube, but it is now further improved with a rear access, enables a quick and easy plug and unplug to take out the seatpost, and facilitates the cable replacement and adjustment.

A triple guiding line based on a square shaped linear guides system completely eliminates any radial/axial play. In addition this avoids radial flexion and guarantees a longer life than other guiding systems based on cylindrical pins or bearing balls.

MCL System was improved with low-friction polymers and a redesigned piston profile that achieves a smoother and silent activation, and a faster response.

Blacx Jewel 2010 Dropper Post

On the Blacx Jewel 2nd generation I did an extensive redesign of the whole seatpost for mass production.

As well as a new remote lever, minimalist and versatile, consisting of only two parts. The lever slides around the handlebar center, using the slotted clamp body as a rail. And the thumb moves naturally while hand keeps holding the handlebar firmly.

The first Jewel Seatpost, it was the first implementation of the Magnetic Locking System (MCL), a system that allows an external but ergonomic cable routing without drills at the tube walls.
