Description:

As I visit and stay in Portland recently every year,

I also go out for ride and see whats going on every scenes as possible.

Then this is what I poped out. I guess choice of smaller frame sizes are less numbers than over 54.

Geometry is customised from my basic model but not a scale down. (Hmm...that sounds like iPad mini)

This frame is designed from function and made to fit with selected components; crank arms length, wheel size, brake types and gear ratio.

Hope you'll love to ride everyday.

Features:

This bike is available with complete.

Blending Columbus SL and SLX (these both were the high-end racing steel tubes from 20th century) has great vibes.

My trend is using high specs into daily, like a sports car but has utilities.

Hand shaped BBshell in old Italian style, eyelets for mudguards and fenders including Helavna handmade front & rear racks, made to fit with Ortlieb pannier bags.

Rack-brakes mount bolts adapters are also made in house, and hand built wheels.

Little more about Helavna:

Building fully-custom as standard in central Tokyo, JAPAN. Also production model made in high quality are also available. Likes riding, travel (especially to Portland), coffee, beer and Good foods.
