Hello Everyone

I have an SR ALPINE SPORT Road bike I am refurbishing. I have found no info on the web, apparently SR went out of business before the big web boom. The SR appears to be low to mid-range for the time period. The Dia-Comp brakes have markings for 1983, so I am assuming this could be an '83-'84 model. All the components are Suntour and wheels are Araya, the stem as a very long Nitto of 66mm. There is a sticker on the seat tube saying "Champion No. 5, Chrome Molybden Steel, Seamless P.G. Tubing, Tange Industries, LTD".

I had been to a thrift shop where I had seen an old Bridgestone that resembled the frame, but it has a few small differences, such as the smooth dropouts on the SR. The Crank and arms are SR Custom aluminum.

I bought an SR downtube shifter to replace the large stem shifter and looking for a 120mm or 130mm handlebar stem.

If anyone knows anything about these bikes and if they are worth upgrading, I would GREATLY appreciate it.

P.S. I replaced the front Dia-Comp brake with an old MAFAC Racer I had laying around, thought it might work, but it seems a bit too long, I have the pads as far up as possible.

Tange INdustries is in Taiwan I believe...This bike is somewhat Light CRMO right... I had a SR GRAN Course long ago it is ok...Suntour makes great roadie deraileurs..not cheap. I might have a stem for you....I will look at Bianchi Stem and see if it can help what size diameter. But otherwise looks sweet. Maybe you should convert it to a Single Speed...Would be Chill!

Hey there wasabiboys

Yes, it feels light for a bike that era, slightly heavy compared to decent bikes of present.
There is a sticker at the bottom of the seat tube that says "Made in Japan", its the same sticker I have seen on a Univega.

Overall, it doesnt feel cheap, it feels like a solid chro-moly bike and the SR components look solid.

I actually like this bike for some reason, its almost perfect for me, it could be 1/2" to 3/4" shorter, but I can live with it.

Let me know what kind of stem you have and how much you'd want for it, would be good to ride this bike, the fork is a 1", the Nitto it had before said 22.2mm, if I remember correctly, it was just too short, I tend to have a longer reach or longer body than my legs, I dont know, so a 4"-5" inch stem would suit me. Please do email me. Thanks and glad someone has experience with this bike company.
