Among those who love to drive, very popular bikes legkodorozhnye a transitional type between the road and sports velomashinami. They are easy to move and high maneuverability. Afforestation of their weight is achieved by using stainless steel, light alloys and narrower tires than road bikes, and improved maneuverability - by reducing the base. The use of free-wheeling hub with "ratchet" and relieved of tires and wheels provide these bikes increased ease of movement.
"Tourist" meets the design constraints and design complexity is when mounted on the brake velomashinah sleeve. Free running performed by the mechanism of "ratchet" (Fig. 20b), so-called for the characteristic crackling when the wheel rotates.
Now our industry produces three models of this type of bike: men "Tourist" B-31 and B-32 and B-41 female.
Male model "Tourist" B-32 is different from the analogous model of "Tourist" B-31 presence of the sliding switch. Ladies V-41 has an open frame with straight, parallel to the location of the upper and lower tubes and equipped with two-roll switch and turning the wheel straight.
Legkodorozhnye bikes are designed primarily for driving on roads with hard cover, but can also be used on country roads with compacted soil. The name "Tourist" assigned to them, not entirely successful, as on terrain, reliability and the ability to carry the tourist baggage they, of course, is far inferior to velomashinam road, having before them only the advantage in speed and ease of a speed.
Bikes such as "Tourist" are different from road velomashin some features (such as the presence of netormoznoy bushings, transmission shift, and others), which we will touch on in this section. The remaining components and parts, such as the frame, slide, etc., are not much different from those parts of road bike, except the weight of a changing style and so on, and so they are, we shall not stop.
Netormoznaya rear sleeve with a free-running
One of the distinctive design features of domestic legkodorozhnyh netormoznoy bike is the presence of a free-running hub on the rear wheel. This sleeve is required for maximum ease of movement, and also because the use of the type of shift
