Having just bought my Son the Rockrider 540, he's looking to fit a higher end, possibly single pully crankset, once the one he has now begins to show signs of wear.
My question is, does anyone know which cranksets would be compatible with the 540 frame. He's looking to install a 2-piece crankset.
We seem unable to find specific details on the bottom bracket sizes, only that it is a Square Taper cartridge.
Thanks in advance for any help received.
