Hi,i own a nishiki arrow speed and I whant to know more about the bike,like age?

Posting some Good pics will help.

Welcome to the forums. I've never heard of this model before, so I'm assuming it's non-American market. The combination of a single water bottle boss set, forged dropouts and cables running over the BB shell suggest very late 1970s to early 1980s. Brakes with recessed nuts from this period would suggest at least mid-range. However, the Nishiki serial number formats are well documented and should tell us the exact age. Any tubing decal?

The components aren't much help, as most would appear to be non-original. I'd appreciate detail pictures of the crankset, brake calipers and shift levers as these look like them may be original.

Welcome to the forums, nice bike too.

Paul.

Please post the seatpost diameter, as well. (Larger is better, generally indicating more expensive, thinner-walled tubing.)

the serial Numbers EC102404
The previous owner canged the handelbar,break levers,the de-railer (back gear)and more.Al because the original was either broken or worn out.

Made in 1983 for the European market by Kawamura., which at least explains the unfamiliar model name.
