Feather Tech

Feather Tech butted frame tubes have an incredible ROI. When you are creating working art like a custom titanium bicycle frame, go the extra step and offer something a cut above the competition. Would your customers even consider a straight gauge steel or aluminum frame? When you consider how much is already invested in all the small parts like dropouts and braze-ons, the upgrade to Feather Tech butted tube makes great sense.
