Mám nový bicykel (Kellys Tyke 30) a po 50-60km začalo niečo pukať pri pedálovaní, približne raz za otáčku pedálom.
Pedále to nie sú, vymenil som ich a stále to robilo. Sedlo to tiež nie je. Zdá sa mi že to ide zo spodu z pravej strany ale neviem presne lebo zvuk sa šíri po ráme. Čo to ešte môže byť a ako to opravím?

Bottom Bracket Cups/Retaining Rings Loose?
Because of the threading of normal bottom brackets, the cups are self-tightening to a point. This sometimes leads to careless installation, particularly on the right (fixed cup) side. If the right cup is slightly loose, it won't necessarily unscrew itself, but it won't really tighten itself up fully either. The symptom of this is an occasional creak or clunk usually as the left crank goes "over the top" when pedaling hard.
This is a surprisingly common, and frequently missed, cause of unwanted noises. Generally you should check the items above first, because they're easier to deal with. You can't reliably check the tightness of the bottom bracket mounting without removing the cranks, but sometimes you can diagnose it this way:
Turn the cranks so that the left crank is alongside the seat tube, wrap both hands around the crank and seat tube and squeeze the crank hard toward the seat tube.
Then turn the cranks so that the right crank is alongside the seat tube and repeat this. Listen for a creak/click.
Nejaká jednoduchá oprava? Nemám ten špeciálny bottom bracket kľúč, mal by som ho objednať?
... k tomu stredovemu zlozeniu potrebujes kluc na to, ale neviem ake tam mas
Čo som už skúšal a určite to nie je: pedále, kluky, sedlo, sedlovka
savings Shimano TL-FC32 plochý kľúč na misky Hollowtech II
8,19 € savings
MOC 14,99 €Bolo to toto (prowheel), kúpil som na to klúč (Hollowtech II), nebolo to zatiahnuté poriadne. Rozobral, vyčistil, zatiahol, bicykel je tichý.
