New rim for a 115mm dropout - '76 Shogun
I'm trying to restore a '76/'77 Shogun 12sp road bike.
About 10 yrs ago, the 27 inch rear rim needed replacement and the choice was a Sun M13II in satin finish.
Problem there is it didn't match the chrome Araya in the front. Now I'd like to correct that.
The rear drop out measures 115mm w/ the wheel removed. With the wheel in it spreads to 120mm. It's always been this way, since new it's always been a bear to pull the rear wheel.
I see the M13II is still available in 27 inch, and so are the gumwall-looking panaracer tires in 27 1-8th so while I can probably fit a 700 rim on because the DiaCompe brakes will adjust, I'd rather keep it as original as possible.
The rear hub is oriinal and unknown, the freewheel I believe is Shimano, and I think it screws on (it's been replaced and is still smooth). The cluster is also Shimano, 6sp. Deraileur is Shimano 600.
Thanks in advance for your help. I love this old bike, it's red with pinstriping on the frame and was quite a looker in her day. I hope to bring those days back. Any suggestions, leads, opinions are truly appreciated.
By all means go with the sun M13II. It could be a tad bit different iteration than the one you got back then, but it should match quite well. As for hubs, if the hub is high flange, get something high flange off ebay to match. See if you can read it. If low flange, you can't go wrong with a vintage shimano 105 or 600 front hub. Build with double butted spokes if you can afford it. You're on the right track.
Also, you can spread the rear stays permanently wider. Just pull em apart with some extra force. be careful though, it takes less force than you think.
Currently using a Sun M13II 700c on one of my rear wheels. It's an excellent rim for the money.
