1986 Miyata 310: Modernize?

Hi y'all,

I just bought a lovely Miyata 310 locally for $80. It is equipped with 6 speed shimano golden arrow parts, 700c rims, triple butted frame, and Magnalite fork. Based on the catalogs, I believe it is from 1986. The teal color is fantastic.

I originally bought it with the intention to upgrade to a newer 9 speed with parts I have lying around. So replacing wheels, sti shifters, and brakes. But after picking it up and cleaning it, and seeing how good condition the paint and parts are, i'm torn between keeping it all original or modernizing it. It looks like its been barely ridden at all.

So the question is, should I keep it all original, or use it as a frame set. And, to the people who have had ridden 310s, how is the bike overall?

Nice find. The Golden Arrow stuff is well-regarded. One issue with going the STI route will be DT cable guides for the top-mounted shifters. I do like this frame as a candidate for modernization, though. Some modern black kit would look nice against the teal.

Yes, a black groupset would look very nice. Hmm, didn't even think about the top mounted shifter problem. I wonder if the shifters attach like standard downtube shifters to the 'boss'....

310’s in the 80’s like this one are fine bikes excellent frames. On my daughter’s with bar end shifters, I used a fitting around the down tube that incorporates cable housing stops and just used a screw to fill the open hole in the mount. Such cable housing stops are widely available, like this:

https://www.amazon.com/Origin8-Alloy...=AMY4I718ZUBOU

Or ask on the C&V Sales sub-forum.

But the golden arrow studs is also very nice.

Set it up so that you’ll ride and enjoy it!

I love those top mounted shifters. (I'm a DT guy from decades ago but hated that I regularly hit the right shifter with my knee if I didn't think about it when I was climbing walls. 18% grades in 42-13 isn't fun! So when I saw (SunTour's version of) those shifter, I was all over them. Have them now on my two geared bikes, one 7-speed, one 9-speed.

If you can shift DTs, consider upgrading to 9-speed, spreading the frame to 130, aero brake levers, your favorite pedals. (Campy 9-speed is now wel down in price and shifts manual much better that Shimano, IMO. Actually harder to shift, but in real terms for us manual guys, that means more feedback and our shifts doing what we want. I have done this with several good 1980s frames and always loved the ride. Also that the bike looks clean in a way that brifter bikes never do. (You also have that wonderful full length rear brake housing on top where it looks right, works really well and you never scratch paint picking up the bike. (Why did that ever change?)

Oh, Campy 9-speed and those levers will give you shifting (and the range of gears) that that the great racers of the 1970s would have died for!

Ok, I think I will just give it a quick general overhaul I do to all my bikes; hubs, bottom bracket, headset, brakes, shifters, and derailleurs. If I like the ride, and have the time, I'll change it over to a 5500 groupset and open-pros i have laying around. The rims are in look nice and vintage, maybe I'll relace them to a 9-speed freehub. hmmm.... Ohh the options..

Dude, keep that bike original. Get a Sunrace freewheel with ramped teeth, it will shift into gear much smoother. And Cane Creek Grey Matter brake blocks. You'll be surprised how well those brakes will work.

Great bike! Miyatas of that vintage are really nice. I'd keep it original. Keep an eye out for something not so pristine to use your modern parts on.

Whatever will make you enjoy riding the bike more short of permanently ruining the bike.

If the Golden Arrow stuff functions as well as Arabesque stuff- then it's perfectly replaceable.

IMO you want a nice looking frame to hang new parts on. The 80s and 90s had those gloriously teal/turquoise frames- there's something irresistible about teal to me. They look great to begin with- and a well chosen modern-y group only enhances it- especially when it's being ridden. Why would you want a beat frame to build up a bike with new-ish parts on? Especially when the stock group is as unremarkable as a pre-SIS middling friction group. My opinion changes somewhat if you're talking about 105, or later 6200 or 7400.

IMO, there's nothing "special" about this bike. Not saying it isn't a really cool, well built bike - just that it's not historically significant; it's a mid-level Miyata- a great bike that should be ridden with enthusiasm.

As mentioned, you'll have to find a solution for the down tube cable stops. And a "classic" looking group- not bulbous swoopy components.

If you google around, there are a few threads that show how people made mounts to fit and allow for STIs to be added to the bike.

Whether or not to update- i vote you do whatever is needed to genuinely like riding the bike as much as possible. If that means updating, then have at it.
