Back

The frame is the basis. We deliberately chose a steel frame (CrMo), which is lightweight due to the various thicknesses of the tubes and retains the ideal features for everyday use, trips, and challenging expeditions. Steel is real... it absorbs vibrations, is strong and durable. We choose all the fittings with maximum care. You will always find the full line of Shimano parts, plus Humpert, SKS (Germany) Herrmans (Finland), and Spanninga (Netherlands). Nothing should let you down!

Bike size

A bike frame that corresponds to the height of the cyclist is the primary and most important requirement. Kolos No.4 and 5 are made in three frame sizes that are suitable for the following heights for males and females:

The rule of thumb is that it’s always better to have a slightly larger frame than a smaller one. Likewise, both male and female cyclists who have long legs should choose a taller frame if their body height is on the borderline shown in the table.

Colour

The choice of colour, for example, of the frame, is entirely up to you. If you prefer something other than our colour choices in the menu, you can select “other RAL” and specify your preference in the note section in the order. We can supply you with a bike of any colour according to the basic RAL colour chart. Note: Always choose the colour from a printed paint colour chart during daylight. PC monitors and artificial lighting often distort colours. A RAL colour chart is available from all paint stores.

Parts and types of brakes

For parts for Kolos No.4 touring (cyclocross and trekking) bikes, we exclusively use complete sets of Shimano components in five options:

We recommend fitting Alivio + V brakes for recreational cycling. We recommend fitting Deore LX + V brakes for demanding cycling and touring. Deore LX + hydraulic disc brake installation is more suitable for everyday use in urban traffic. If you appreciate easy handling, the option to change gear even when the bike is stationary, and the absence of a front derailleur, then we recommend the Shimano Alfine hub gear.

Suspension

For Kolos No.4 touring bikes, you can choose between a fixed or suspended front fork and a fixed or suspended seatpost. Suspension certainly enhances comfort in the event of an uneven terrain; however, it also increases the weight of the bike and therefore lessening power transmission efficiency. We use the Suntour NCX-D suspension fork and the Humper Ergotech seatpost.

Lights

We offer a choice between two types - AAA battery powered lights and dynamo hub powered lights.

Battery powered lighting weighs less, but is less powerful. The dynamo hub light is slightly heavier but delivers top performance with no need for battery replacement. In addition, a dynamo hub can be used as power source for recharging your phone or navigation device (in combination with Deore LX and Alfine parts) when connected to a suitable battery charger. The lights are fitted with a Standlight system (the lights remain on for several minutes after stopping).

Accessories

Depending on your requirements, you can have your bike fitted with mudguards (quality SKS sandwich – plastic + aluminium, long), a front and rear rack, bottle baskets, bags on the front and a rear rack, and a cyclobag that attaches to the handlebars. You can choose depending on whatever you intend to do with your bike.
