The old tires (mitsuboshi hill top) are ripped about 1cm.
So, I have changed the new tires , Hutchinson coyote 2.1".
I am happy to got the nos skin side tires.
The bike came with the shimano spd pedal(PD-M525).
The pedal works very good, bearing rolls smooth.
But I don't have any spd shoes.So, I bought a new pedal.
The old school pedal is SR(SAKAE) SP-474 made for BMX in 80's.
I got this 880YEN from Yahoo auction.
