SK Ku kladke niesu pribalene srobiky, rotacia sa mi zda byt trochu pomala ale to asi az tak nevadi. vpodstate funguju a vyzeraju dobre.

The pulley is not compatible with the entire range from Sram, the NX chain skips on the pulley and it has an impact on shifting (detected immediately after putting it on the servo stand). I complained about the product, I'll see how the seller reacts to it.

Product questions
virtu1983 virtu1983 • 22 April 2022 at 20:51
thumb_up0thumb_down

Could you please give me information on how the number of teeth on the lower pulley and on the upper pulley affects the speed, or if there is a difference in pedaling, as in the case of a gear change?

SK Dobrý deň ,

pri prechode na ramienko, resp. kladky s väčším počtom zubov sa naozaj mierne zmení charakteristika radenia, resp. kvôli zmenšenému treniu dochádza k istej úspore výkonu - avšak netreba zabúdať, že úspora wattov záleží samozrejme od viacerých faktorov (napr. prítomnosť keramických ložísk na kladkách alebo stredovom zložení, správne namazaná reťaz a i.).

Viac o kladkách sa dočítate napr. tu: https://www.bikeradar.com/features/friction-facts-bigger-pulleys-really-are-more-efficient/.
