Hi,
I have a wisper 905 the frames about 10 yrs old, the chain ring guard has broken, does anyone know where I can get one? i`ve been looking online they all seem too small, i`ve measured the one off the wisper 905, its 22.5 cm wide, the inside width is 18.5 cm,
hope someone can help,
regards,
Stuart
