Nishiki Altron 7000
I have a Nishiki Altron 7000. Bought new in mid 80's. Rode extensively and its been hung up for last 10 years. Except for dust it is perfect.
My problem is I want to start riding again and wondering what specs are on my bike so I can attempt to modernize if I can.
Everything is in good shape but after all these years I want to do new chain, sprockets, freewheel, or new wheels with cassette that might work with index shifters, bearings, etc.
Anyone know what specs were on this model or where I can find help???
Thank you!
