All G2 models feature the X12 thru axle system. Low weight and increased rear frame rigidity are the main features. Bikers benefit from better power transfer and increased stability even on the roughest lines.
Fitting and removal of the rear wheel requires a 5mm hex wrench. On the drive side a threaded insert holds the replaceable gear hanger. The insert can be replaced if heavily worn. Both dropout sides are machined with cut-outs which make rear wheel fitting easier.
