Hike-Use, from
the french word randonneuse,
a hiking bicycle:

For the pleasure of pedaling
To experience the real world
Specially adapted for long distances

Applied Tunk philosophy

Simple and rustic technology combined with a highly refined design.

THE IDEA

A touring and multipurpose frame set built with a lightweight, flexible steel construction.

Wide tires for all roads and varied routes.

Classic cyclotouring geometry with finely tuned sizing and tubing for a near-custom fit & feel.

Materials and manufacturing from Europe: designed in Finland and made in Czechia by Fort Frames. Columbus and Reynolds tubing from Italy and the UK.

SPECIFICATIONS

For speed and comfort under diverse conditions

Front-load optimized low-trail steering geometry

Mounting points for handlebar bag rack, low rider front  and rear racks. Please see the "How to load article"

Exactly placed mudguard mounts for good and proper installation of metal mudguards.

Internal dynamo routing through the fork and frame. Rear exit ports at the BB shell and near left dropout

Strong 3 layer paint: anti-rust primer + powder coat + clear coat. Internal anti-corrosion protection.

Frame weight: ~1850g for size "53", ~2150g  for "59" and ~2350g for "63". The 650b fork weight is ~900g. 622 fork weight is ~1100g (with cut steerer).

Frame and fork safety tested to EN ISO 4210 standard in the category 'Trekking'

STANDARDS

Compatibility for proven, reliable parts. Mature bicycle technology.

Tire clearance on sizes 53-59 is 48mm  with mudguards and 52mm without. On sizes 61-65 rear clearance is 45mm  with mudguard or 48mm without, front is 48mm with and 52mm without.

Wheel size scales with frame size: size 53 uses 26" wheels. 55,57,59 use 27,5"/650B wheels and 61,63,65 use 28" wheels.

Sizes 53–59 use a 1” threadless headset. sizes 61-65 take 1&1/8” headsets

Standard "road" 100mm front and 130mm qr axles

Brake posts for cantilever or v-brakes. Integrated rear cable stop

Seatpost size 27,2mm. Front derailleur size 28,6mm. 68mm BSA threaded bottom bracket

Downtube shifter bosses/housing stops for any shifter type

FRAME DETAILS

GEOMETRY

The frame is optimized for comfortable long-distance and everyday riding. We recommend a large frame size to get a nice high handlebar position, about level with the saddle. This is the so-called classic “french fit”.

We have also scaled not just the frame but also the wheels. The framesets use 3 different wheel sizes. This makes it possible to avoid many compromises in design.

For choosing the right size and more information on fit, please see the Sizing Guide article.

TUBING

The 7 different frame sizes scale not only in size but with progressive rigidity of the frame and fork tubes. The small sizes use thinner, thus lighter and more flexible tubing. The medium sizes use tubes that are a bit stiffer, and the largest sizes have already considerably heavier tubing.

The colors indicate stiffness progression, green being most flexible, yellow medium and so on. SL, ZONA etc indicate the manufacturers’ model name. The first number below is the tube’s outer diameter in millimeters, and the second number is wall thickness. For example, the top left corner is a Columbus SL top tube with an OD of 25,4mm and butted wall thickness of 0,8mm in the ends and 0,5mm in the middle.
