In recent years, Shimano has been producing chains of the following types: Super narrow HG, designed for mounting on bicycles with 9-star cassettes, HG (Narrow HG) and IG (Narrow IG), designed cassettes for 8 and 7 stars. Sometimes, on the cheapest bicycles equipped with Shimano Tourney ratchets, UG-30 or UG-50 chains (6-7 stars) are also found, which are theoretically designed for use on smooth stars. A digital index in the marking, for example, IG-70, indicates the class of the chain: the larger the number, the better and more expensive the chain.
Spring is here and it’s finally warm enough again to get back on the bike and hit the trails. While for some, it’s time to get your bike serviced and put air in the tires, for others this could mean the start of a new hobby.
Remember how you learned to ride yourself? Remember how your knees were broken and thought that you could never master this science in your life? However, everything turned out to be not so difficult and the childhood experience is remembered with an involuntary smile on his lips.
The bicycle chamber is installed inside the tire and filled with air. The softness of the wheel depends on the amount of air inside the chamber (pressure). The higher the pressure, the stiffer the wheel and the less its resistance on the road, but the higher the vibration on the ground.
Do you like to ride, camp and explore in Montana’s Custer Gallatin National Forest or on the Western Slope of Colorado? If so, we need your help to understand the economic impact of mountain biking and outdoor recreation in these areas.
The basic rules of cycling pedaling are approximately as follows. Pedals need to be turned, not crushed. Do not twist “slowly – but surely” a large gear – it is better to use a lower gear at high speeds with your working cadence (cadence). Try to ride in the saddle as much as possible (do not get up in vain) – this saves you energy. On prolonged lifts, do not strain your whole body – concentrate on the road, breathing and pedaling – but try to keep your body relaxed. Now consider all these rules in more detail.
