Helmz

HELMZ is a sports bicycle from Bridgestone Cycle Co., Ltd. jointly developed with fashion brand narifuri.[1][2]

Helmz H1 2009

Overview

Bridgestone Cycle's 60th anniversary model was developed as "bicycle to be a part of fashion"[3] with narifuri taking charge in frame design and concept establishment. It is made with an "approach to create focus on design ". The model was announced in 2009 and was sold starting in 2010.

"We will jointly develop a new brand (with narifuri)" and propose a new genre "Speed Cruiser" born from the city streets.

The name HELMZ was taken from the English term "helm."

Custom-designed original parts were made for HELMZ, by Japanese cycle part brands such as NITTO, MKS Pedal, and Sugino. Japanese oriented brand parts were selected carefully to minimize the use of Shimano parts.[4]

These original parts of HELMZ are sold as aftermarket cycle products. The entire sales plan, including the package design of selling boxes and POP, was awarded the Minister of Economy Award and Planning Award in 42nd JPM Creative Design Show in 2012. SR1 received Good Design award in 2014.

Technical features

Air pressure formed aluminum frame

The frame was based on a Top tube, sloped, low-front design from narifuri and was manufactured using SPF (= Super Plastic Forming) which molds the frame by inflating high air pressure in the 7005 aluminum pipe. Bridgestone cycle usually used this manufacturing method to improve riding performance, but in HELMZ it was necessary to realize the design.[5]

Wheels

The texture and rim height differ in front and rear wheels. The front wheel is silver with 35mm rim height. The rear wheel is black with 38 mm rim height. Models with high-performance sports wheels were launched afterward.

Thumb shifter

For models with gear shifts, the Thumb shifter was selected. This shifter is operated with the thumb unlike the typical modern sports bicycle push bar mechanical shift.[6]

Original aftermarket parts

HELMZ original aftermarket parts were released on 2012. Stem, handle bar, saddle, wheels, gear cranks, and most other original parts were sold on market as aftermarket parts.[7]

Belt drive

The belt drive equipped models, SR1 and S10, were introduced in 2013. These models were an update of Bridegestone's belt drive experience from 1980, "SSSD" (Selectable SS Solld Drive). The new belt drives were made out of carbon instead of kevlar making the belts lighter and more flexible.た[8]。

Benefits of Belt Drive
  1. Needless of maintenance
  2. Kept clean from no lubes needed
  3. High abrasion resistance, 3 to 4 times usage period compared to chain drive[9]
  4. Sounds less for not having metal abrasion sound
  5. Lighter than chain[10]

Using Sliding straight drop rear end

The rear end itself slides to adjust the belt tension. No tensioner is needed and made gear changing possible. The gear pulley has three changeable gears.

From its original rear end system, a quick release system could be used with belt drive. A gear pulley meets the modern sprocket standard to accommodate the latest high-performance sports bike wheels that could be utilized.

Models on market

Frame shape and concepts have not been changed since its first announcement except for the new sizes being set.
