T-Mar, Is there a way to access the aforementioned serial # database?

would anyone know if a surly fixed/free hub 135mm will fit on a miyata sport 10 speed bike

2 options:

1. Stretch the Miyata frame to 135mm which will require re-alignment of the dropouts or:

2. Respace the hub (if possible) down to a more compatible width. Surly hubs have replaceable threaded axles and they appear to have commom hub shells so you may be able to take a spacers to bring it down to Surly's 130mm size to minimize stretch on the Miyata frame

i know i should measure the frame first before i buy a hub i was just looking at stuff on line and came across the surly hub i think they do have a smaller one or atleast i can find one if anyone could suggest a good but cheap hub for ss that would be great thanks for the tips

Anyone ever hear of a Miyata Pathfinder?

Another Miyata in need of a date. I think it is a Miyata 610. Light Blue paint, black Avocet seat, S/N J438366.

Cro-Moly frame, Suntour derailleurs, everything is original except the seat and the former front wheel that were destroyed in an accident in the mid-eighties.

I would also love suggestions on what wheels to put on it. The bike has a lot of miles on it from Triathlons and tours when I was younger. I love the bike and want to use it as a commuter, but the original front wheel was turned into a pretzel and the spokes on the rear are past redemption

My commute is 15 miles over the Golden Gate Bridge.

Also, the original Suntour Rear Derailleur is likely past its prime. I am going to look for parts, but can anyone recommend a replacement?

Thanks!

I think a J prefix means a 1981 bike.

T-Mar, If you have a Miyata database maybe you can tell me more about my wife's mixte. It is triple butted Miyata chromolly but there was no model number when I got it. I believe it is early to mid 80's. The serial number is PU38615.

for the miyata sport 10 does anyone know what kind of bottom bracket it comes with

British...square taper with nuts...not bolts.

thank you

Just got a Miyata Ninety (spelled out that way in script on top tube) for $10. Serial M251455. Entry level, Shimano Skylark rear derailler, 5 spd freewheel, steel rims, alloy cranks & rings. "Made in Japan" sticker, "Mangalight" manganese steel. Tange chrome fork, rusty but managed to clean it fairly well. Suffering from dire neglect; lots of rust but might clean up well for repainting.

Also surprised at how light the frame is! Tubing seems to have pretty thin walls. The fork seems nearly as heavy as the frame.

Components are mostly trashed; deraillers seized. Might sell frame only, or build it up for my teenage niece if she is serious about joining her uncle on a century this summer.

i have a miyata sport 10 it has 27'' wheels and i was wondering would i be able to put a disc wheel on the rear and if a 700c would work

yes, and yes, but I would say no don't do it.



On another note:

Have any of you come across 310's with Shimano Golden Arrow components?
Mine came fitted with golden arrow, RD, FD and Shifters, or was done after market, but have no clue or info.

For those interested in Miyata's...go to Miyatacatalogs.com

Wonderful site with catalogs from 1984 (I think) to 1994 posted. Something like that anyway - I'm too lazy to check. Enjoy!

I don't have a serial number on the BB of my miyata ninety. I can't see it anywhere else, either, although it's fresh from the seller and literally has mud caked on it.

Any other places I might look?

It says chromoly on it, but the fork and stays sound like hi tens when I tap them. The chromoly tubes sound butted to me, but I'm no expert. they "ting" differently on the ends.

I have a Miyata 310 that I purchased new in 1984. It came with the Golden Arrow RD, FD, and shift levers. I don't know about any other years.

I could buy a whole fleet of vintage bikes for what I've paid for my son's college tuition just this year. What's wrong with selling your children? And if I got rid of my wife... (Mmmmm...I can see Fausto Coppi's Bianchi on the wall in my den...)

why would you suggest not using a 700c wheel

some basic info here: https://en.wikipedia.org/wiki/Miyata

• "Miyata 100/110 : This was the bottom of the range. Chromo main tubes, hi-ten stays, available in both men's and mixte styles.

• Miyata 210 : This was a touring model. 1984 catalogue says the 210 used straight-gauge tubing. Dia-Compe cantilever brakes and Shimano triple drive train. Braze-ons on front and rear dropouts (no low-rider braze-ons in front), cantis front and rear, horizontal rear dropouts, one bottle braze-on, rear rack braze-ons, and flat-top fork crown.

• Miyata 310/312 : This was a mid-range "road racing" model, with Shimano 105 throughout. The 310/312 had a shorter wheelbase than the touring models, but still plenty of clearance for fenders and wider tires. Sometimes it's referred to in newsgroups as a "sport-touring" model--a comfortable rig for day rides and commuting.

• Miyata 512 Competition : This was a higher-end road bike than the 310/312, with more "aggressive" geometry.

• Miyata 610 : This was a quality touring model, one step down from the 1000, with the same frame, but slightly lower level components. Mid 1980's 610's have triple-butted splined Chromoly frame tubing, very unusual quality tubing and construction for this price level. This bike is slightly lighter in weight than Trek 520/720 touring bikes, but of similar quality.

• Miyata 710 : A mid- to high-end road bike. Early models had Suntour parts, including an odd 3-wheel rear derailleur. Probably uses the same frameset as the 910.

• Miyata 912 : Miyata's high-end road bike, with Shimano 600 components.

• Miyata 1000 : This was considered the finest, lightest off-the-peg touring bike of its time, with splined, triple-butted Chromo tubing. Some report the 610 to be stiffer than the 1000--probably a bit better for loaded touring. 1997 model had a mix of Shimano 600 and Deore XT parts (600 DT shifters, XT derailleurs). Miyata 1000 is still considered one of the finest stock touring frames ever.

• Miyata Alumicross : This was the top-of-the-line model of Miyata's "cross" bikes (which included the Quickcross, Sportcross, and Triplecross), introduced in the late 90's. It had standard-size aluminum main tubes bonded to steel lugs and a Chromo fork. Seat and chain stays are steel, with the seat post binder bolt holding the seat stays to the seat post lug."

i'm looking for a new crankset and was wondering would i have to change my stock bb if i was to get a new one the shops around are selling sets for 80 where online some are less than 60 what do you guys suggest i was looking at this Track Pista single speed bike crankset 48T 170mm Matte
messenger courier winter beater matte light weight 1/8"

can anyone help me to identify my miyata...i just picked it up from a friends house and i dont know anything about miyata...ive looked through the whole heirarchy also and cant find it in there....it looks 70's maybe...on the top tube is spelled LIBERTY... i have googled it but the only thing i can find about the liberty is a picture of one from '77 but i dont think it really look like mine...all the other stickers on it have been peeled off long ago....it does have bar end shifters on it....the serial # is E982654....any help would be much appreciated....thanks

Well, since this thread has popped up again i just want to mention another exception to the guidelines stated above. There was a Twelve Hundred model that was only produced for, I believe two years. It was built with triathlons in mind (sticker on chainstay shows a biker, swimmer, and runner). It was constructed of Miyata triple-butted splined steel, frame and fork. It had internal brake-cable routing and came equipped with the also short-lived Shimano Sante group. The group was white and fell in between 600 and Dura Ace in the line-up supposedly.

Wow I am so impressed with the vast knowledge on this site! It's so exciting to meet other Miyata lovers! I got mine as a trade, plus $25 - I traded a 70's Azuki (10 speed) that was too big and heavy for me for it - my Miyata is the perfect size and weight for me, so it was a perfect swap!! I'll try to attach pics of it and also of my other bike, which is the one I'm really wondering about - the Schwinn has a FUNKY derailleur - is there anybody out there who can give me some details on my Schwinn? THANKS!!!
