First time riding 650b so felt strange and squishy to start with but was loving it by the end. Just begs to be unleashed on gravel. Love the surety a disc brake brings. Started to notice a rythmic bump going from the front wheel. The tyre beads in one part had bedded in the depression of the rims. Took a lot of washing liquid and overinflating the tyre to solve.
First puncture I get I am going tubeless the tyres were an arse to get on.
