T-Mar I picked up another old Takara today. It is a model 970 Grand Touring with the serial stamped on the seat tube. The serial is 80 7 49463 which I assumed is a 1980 model. Suntour V-GT Luxe on the rear and Suntour NSL on the front. It has a Kuwahara headset but I don't know if Kuwahara built the frame. I would appreciate if you could tell me a little more information about when it may have been produced.
Thanks
Thanks

I picked up an interesting bike today; mid-'80s KHS Montana Sport. Serial number: 41C 7509, which doesn't seem to match anything. No pics yet, as it's upside down in the kitchen, drying after spending too many storms on a balcony. Any ideas of its age? Any other info? It looks like an early Stumpy knock-off, with a biplane fork and bullmoose handlebar.
Hopefully we can get that last hornet out of the handlebar tomorrow.

GT ZR 2.0 Roadbike 2001 Model
Theres not much info on the specs of the GT ZR 2.0 Roadbike now. Would anyone know the GT stem specs of the size 52 frame ? I plan to get the right specified stem for this old model frame, which i got recently. Its a good stiff frame. This is a 2001 model.

Given that you are asking about a 52cm frame, I assume you're concerned about the OEM stem length. If so, forget about it. Choose your stem length to give you a comfortable riding position. Assuming you've already got your saddle fore/aft position properly set using KOPS or your preferred method, pay attention to whether you pull yourself forward or push back on the handlebars, to get comfortable. That will tell you if the current stem is too long or short.

Ah, thxs for the clarification! Polygon was a Taiwanese brand and one of the dozens that seemed to pop up out of nowhere when ATBs started to become popular in the mid-1980s.

T-Mar I picked up this Bridgestone Carmel mixte for my wife today. The stamping under the BB shell is N380172. Solely with no other information than what I got off of the Sheldon Brown website, I hoped it to be an '82. But after picking it up, it seems to have a Suntour Accushift 4050 Edge RD which I don't know if it dates the bike later 80s or early 90s or if it was a replacement RD. Overall it is a nice bike and should serve her well. But I would appreciate your decoding the serial so I have a better idea of what I have.
Thank you.
Thank you.

I'm intrigued by the lug of the stay to the top tube. At first I thought that was the stay cap, but that's part of the lug isn't it?

Frame was manufactured in mid-1983, so it should be a 1983 model. The rear derailleur is definitely a replacement. The frame is manufactured with Bridgestone's Technart process, whereby the lugs are die cast around the tubing. The seat post uses a expander bolt (like on a handlebar stem) to secure it in the seat tube, rather than a traditional cinch bolt.

Having difficulties identifying a particular bike. The serial number is JP63433, it's a blue colored Norco Monterey Monshee. Trying to decide if it's worth fixing up. I went through all the serial number possibilities and can't seem to figure this one out. It's made in Japan, has a Suntour Seven rear derailleur. Maybe thanks.

I need some help identifying a Diamond Back frame I picked up. It's a chrome frame and believe to be an Ascent. S/N could be 6FQ0305 or SFQ0305 also, the S/N is not on the bottom bracket but towards the bottom of seat post. TIA
You should be able to find pictures under gallery since I can't post pictures yet.

I believe the S/N is 6FQ0305. Unfortunately I haven't enough of these serial numbers to have confidence in their interpretation. Nor do I have anything for the 1985 Ascent. However, this fame is an excellent match for the 1986 Ascent, which was available in chrome for $15.00 US extra.
Thank you T-Mar. Once complete with the build I'll post some pictures for sure. I'm tearing down a similar bike in Teal for parts. Very similar S/N as well. 6FA2378
