    Happy New Year 2022 DMCX friend!

    Yes I am aware I am running behind schedule with my pro bikes review but I have some good excuses.

    See I moved to a Tropical Island in the beginning of 2021 and found myself cycling, running, snorkeling much more than I had anticipated. You may call this procrastination, I call it healthy lifestyle šŸ˜€

  • DMCX Spartacus: All Roads in Comfort

    26 inches ain’t dead!

    Today I will introduce you to my favorite bike: The Spartacus

    It is a 26 inches ā€œAll Roadsā€ Full titanium bike I envisioned first while riding Japan Alpine roads around Takayama (é«˜å±±åø‚), Gifu Prefecture when living in that area more than 10 years ago.

    I wanted to build a totally versatile bike that is equally at ease on roads and off roads, able to climb up Alpine roads and enjoying the snaking, hair pin cornering exhilarating down hill roads in total comfort.

  • Robert’s Ti Bike, from dream to reality

    Few months ago Robert took the wise decision to hire my services to design his new bike.

    Robert is a local rider member of the DMCX Cafe Racer crew and we have been cycling together for a couple of years so I already knew his riding style.

    Knowing the person riding style is helpful in the process of designing a frame that will correspond to the futur owner’s expectation and style.

    The style refer to the looking of the frame and by extension the complete bike, but also the bike riding feels.

    Robert wanted a ā€œDo it allā€ bike that is equally comfortable for daily commuting in all weather condition but also performant in long sportive week end rides.
