Bicycle chains and their manufacturers

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.

About the bicycle pedaling technique

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.
