I recently purchased a Miyata 610. Unfortunately, the fork was either damaged enroute, or the seller duped me. Either way the fork is toast. So, I am stuck in the unenviable position of trying to find a suitable replacement. I'd like to try and keep the original geometry as close to what it was as possible. So my thinking is that I'd like to find a 1" threaded touring fork, with canti bosses, for 27" wheels. The frame is a 54cm and the head tube is 11cm. As you can imagine this is exceedingly difficult. I have only found one fork that matches the description, here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290511780176&ssPageName=STRK:MEWAX:IT
It is expensive, so I'd like to make sure that if I do decide to purchase it that it is going to work for this application. Here are the specs: Threads come down 2" from the top. 7 5/16" long steerer. From center of axle to center of brake bosses measures about 11.25". From center of axle to underside of fork crown measures 14.25
I have similar measurements from my fork and, while they don't match exactly, they are not that far off. I will post them when I get home. So my question is: Is there anyway to know that this fork will work without trying it out first? Is the price of the fork worth it?

While I am not sure if the ebay fork will be the right one for you, what happened to the original fork that it cannot be fixed, bent back, or welded? It may be cheaper to take it to your LBS ans see what they have to say(if you haven't already). On the other hand, you can put out some feelers in the ISO subforum and something may pop up for a better price.

Bummer. When it says 27" fit, I wonder if that means with fenders/clearance.
You might look at repairing what you've got.
I don't think you have much of a choice, the replacement fork you are seeking will probably require you purchase a vintage frameset. What's the real risk here, if it doesn't fit you resell it on eBay, correct?

What happened to the original fork? One advantage of steel is that it can be repaired quite easily. Don't give up on your original fork just because it's bent or has trashed threads, it may be repairable.
You need to know the rake of your original fork and the axle to crown distance to keep the geometry the same. The rake is the more important parameter and specifies how far forward the wheel will be relative to the head tube. This will affect how the bike handles so you want to keep it close to the same. You will need a 1" steer tube and the threads need to start far enough down for the adjustable headset cup to be snug against the bearings and long enough for the headset lock nut to screw on. You can add spacers under the lock nut if the fork is a bit too long and you have enough threads for the adjustable cup.
I'd consider getting a threadless fork, too. You will need a new headset and stem but you could sell your old ones and the selection of new forks will be much broader.

He is asking way to much for a no name used fork.
05-25-11, 01:55 PM
Wow. Thanks for all the responses. The fork is bent back towards the frame significatly, almost in the opposite direction that it is supposed to go. It is so bent that when it the wheel is mounted it almost touches the downtube. I took it to my LBS and he said it looked as if it had been crashed. The seller offered to refund the purchase price, but refused to cover return shipping (which was expensive). In the end he gave me $100 to cover a new fork purchase. But all in all, I was left feeling a little more than screwed. My mechanic at the LBS said he could probably bend it back, but that he wouldnt recommend it, especially for a touring bike, as the structural intergrity may be compromised. He did also tell me that he had one of his forks repaired once, and had it fail, causing him to break a collar bone - so he might be biased. ;)
Aside from changing the geometry, what would the negative consequences of going with a threadless one-inch surly cross-check fork be? Would the handling be dramatically different if I stayed with 700c wheels? I am getting really frustrated looking for a fork that will match the original. Any suggestions of the proper method to "fix" the bent fork?

Soma is now carrying forks, and this one has canti studs and a "classic curve" or bend:
It's for a 700c wheel, however, though depending on the brakes you're running, you might be able to run a 700c wheel on the back of your 610.
05-25-11, 03:16 PM
Oops...I meant if i got a cross-check fork and stayed w/ 27" wheels.
05-25-11, 04:58 PM
You might be able to run 27" wheels with that Surly fork. You could ask Surly and maybe they know. Or as Neal says, you might be able to run 700's front and back. It all depends on how much adjustment room you have with the brakes. The biggest negative is cost. You'll need a new headset and stem if you go threadless but it is a better system IMHO. Then if you go with 700 wheels, you'll need new tires, rims and spokes at least or just a new wheelset.
For the best answer on fixing the fork I'd take it out of the frame and post a question in the framebuilders sub-forum with some good pictures.

This sound remarkable familiar... was the bike an ebay purchase...from a guy named brent? I was browing touring bikes and he has a trek 620 listing... explaining why he has a negative feedback and it sound like your story... but more from his side. Small world out there.
05-25-11, 06:34 PM
Yep. This is the same bike and the same story. I paid $80 in shipping to get it to me, and when it arrived, it was damaged. He claimed that he could not get FedEx to accept a claim because I had taken it to my LBS to build before looking at it. At one point he told me he had a replacement fork from another 610, but then apparently that fork was damaged too. :notamused: Anyway, he said I could return the bike but that he would not spilt the shipping with me under any circumstance. So basically I was going to be out at least $160, just in shipping, if I returned it. He then offered the $100 for a replacement fork. I explained to him that this was of little real help, as finding a truly adequate fork was going to be next to impossible. He said take or leave it....so i took it and left the appropriate feedback. All in all the guy was a condescending acussatory jerk from the get go...overall just a crappy experience. Bottom line here is that I am stuck with money invested in an unrideable bike and no closer to getting to ride a classic 610 than I was 2 months ago. So....good people of this forum. Help :)

Thanks Iowegian. I will follow your advice and pull the fork, take some picures, and post it in the framebuilders sub forum. I also woulndt mind going threadless. I have a stem I could use and a new headset woulndt be terribly expensive, I guess. I think the canti's I have would have enough adjustment to run 27" wheels, but i guess there is no way to know without trying. I'm starting to think I should just strip the frame and sell it and the parts and try to recoup some of my loss...so frustrating.

lionio05... did you file a dispute with ebay... they almost alway side with the buyer and you would get your money back and probably get to keep the bike. If it is not to late to do that I would... it all sound fishy... I've had a few fedex claims and they have never been denied if you have the proper documentation such as photos of the damage, repair estimate, and photo of the damaged shipping box. If there was no damage to the shipping box... It is likely that the fork was damaged prior to shipping... which means your item was not as described by the seller. Sorry for the headache. Good luck finding a fork.
here is what your sell wrote... in response to your feedback... ">>> Note on feedback: After 13 years with eBay and many (many) hundreds of bikes (and bike components) sold, I have sadly received my first-ever negative feedback, which is baffling to me in this instance. (While the buyer claimed his bike’s fork was damaged in shipping, the shipper quickly denied the claim, citing puzzling actions by the buyer in the days following delivery. Still, I felt some obligation to help, offering to refund $100 (or roughly a third of the bike's cost) to the buyer to cover buying/installing a new fork. This seemed to go over well with the buyer -- he promptly accepted the $100 offer -- but as soon as the refund went through, he then left me negative feedback.) Again, I don’t get it, but please don’t let this one disgruntled buyer prevent you from bidding on this bike. If you have any questions or concerns about this Trek, or how I would ship it, or anything at all, please simply e-mail me, and I’ll e-mail you back as soon as possible. Or if you’d prefer to talk to me in person instead, simply let me know that, and I’ll call you when I can (or I'll e-mail you with my cell number so you can call me). Thanks for listening … Brent."

Wow. That is shocking - and just plain wrong. If it weren't such a bore to everyone else i'd post the email correspondence that flatly disputes his account of the situation. As a side note, I just realized that he posted positive feedback with a negative statment to my ebay account. Wow - what a jerk. Turns out though that this is a violation of Ebay terms and he may now have his account suspended. Bittersweet really...I'd just rather have a functional bike.
As an aside, I didnt file an ebay claim because I feared that it would take a long time and a tomn of effort to resolve. The seller also told me with the certainy of one who must have gone through this before, that Ebay would most certainly decide that his resolution was appropriate, and that I would end up shipping the bike back on my own dime and getting a refund. I have desperately wanted a 610 since riding my friends over the winter, and didnt want to have the money I budgeted for the purchase tied up any longer than I had to. Looking back on it now though, I appear to be stuck with a bike that is going to cost a lot to make usuable.

I don't want to add to your troubles but with the fork bent that badly you should take a close look at the top tube and down tube for any frame damage. Feel the bottom of the tubing just behind the lugs that connect to the head tube to see if there is any buckling or rippling of the tubing.
05-26-11, 01:32 PM
Anyway, he said I could return the bike but that he would not spilt the shipping with me under any circumstance. So basically I was going to be out at least $160, just in shipping, if I returned it.
ahh the joys of ebay...
