Classic & Vintage - Familiar with SR Semi Pro?

I bought this bike over the weekend. It says "SR" on the frame, and "Semi Pro." It also says "Japan" down at the base of the bar that holds the seat.

I think someone told me that SR doesn't make bikes any more, only components. I believe this bike is from the late 70's or early 80's. It has all original Shimano components. Works extremely well, too, btw. I think it weighs about 18 lbs. Anyone familiar with it?

A few members here have SR Semi Pros. Use the search function to find some posts about them.
Personally, I can't tell you much about them. I can tell you however, that there is no way that your bike weighs around 18lbs - at least 24lbs is more like it.

My husband's 20-lb. weight must weight about 24 lbs., too. :)

Thanks, Leigh, for the referral to the search function. It did turn up a lot of information. I think, based on what I read, that I got a really good deal as the bike looks like it's been stored under wraps in someone's attic for the last 20 years. Everything works, and there's no rust any where.

All the components are Shimano, and the tubing has a sticker on it that says "CroMo", which, based on what I read in the forums, means that it is a really light frame for its time.

It is a very good entry level road bike. It is probably in the 22-24 pound range. The rubber inside those plastic bushings can degrade so do not take the shifters apart unless you want a headache.

The frame is a very good example of what a midrange/lower end entry level bike should be. The components are well made and nicely finished. The derailleurs are nice when they function right but do have a few plastic odds and ends that make them a little less durable but they shift very well.

Ride it and enjoy it. If there is no desire to climb anything too steep you could probably get the bike in the 21LB range with a single speed/fixie conversion.

Yesterday there was a large frame of the same vintage that went for 91$ on ebay. It is a decent frame and well crafted.

Nice score. For the money, it was a better-than-average midrange bike (I wouldn't put it in the low end), with full 600 Arabesque, Japanese built with double-butted Tange tubing. I used to have one of these and it was very versatile. Comfortable enough for every day, but respectable in a criterium race as well, not unlike say a Trek or Univega of the day) .They were damn strong frames without too much weight penalty and would make an excellent commuter these days. The SR name's origin is unknown, but it has nothing to do with SR or Sakae components. Anyways, your looks pretty true to the original (I think a Turbo saddle is what I had) and nicely preserved. Another C&Ver recently came across a similar one (larger frame) in SoCal as I recall. Not sure where that ended up, but I like seeing them come out of the woodwork.

Thanks, dudeona. I really, really like this bike. I'm hoping to go for a long ride on it this coming weekend.

It reminds me of the Raleigh I had in the early '80's, which was the first expensive bike I ever had. It was $300, which was a week's salary at that time for me. :) That was also a very light bike.

I lost it when I forgot to lock it up one night. It was my commuter bike. That's about when I quit riding because I couldn't afford to buy another bike at that time.
