mrs t2p 7.5 FX
recently showed it some love with upgrades including 35 mm Panaracer GK SS
the tires actually measure around 36-37 mm installed - and this width is the max for this FX : the front wheel / tire must be squeezed / shoehorned through the open front brake pads when installing ... a tire 1 mm wider would prob not work (without deflating the tire)
