Besides traditional bike components tuning, I have discovered an advanced bike tuning with so-called "bike jewellery". Custom head badges, which might be fixed either on the head tube, seat tube, or anywhere you want on the frame, are typical unconventional bike jewellery. Every custom head badge is fully hand-made in the United States and is 100% original.
NOTE. I have to inform you that due to very low interest in this tuning I closed a business relationship with a manufacturer and I do not provide that tuning.
