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: https://cgi.ebay.com/ws/eBayISAPI.dll...=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?

Fork offset differences will change the trail and the so handling, some, as well ..

longer steerer tube than needed will allow a threaded to threadless 1" conversion too ..

I have 2 622/700c wheel bikes, they have the cantilever bosses at a radius from the hub axis of 11.5"

a 630/27" wheel is bigger , by .. r=4mm

It's steel, innit?

Are you sure it can't be fixed?

A few people have suggested this. I don't really know...Here are some pictures. If anyone has any experience with this (whether its possible, where to go, process involved, priice, etc.) I'd appreciate it.

Ask a frame builder, about cost of replacing the blades,
and adding the cantilever/ V brake bosses.
it will cost what it costs to live and work, run a business making things, in a shop,
where you live.

you could specify to add more braze-ons in the process,
before the paint goes on.

Oh and it looks like crash damage, check the frame for damage too..
bending shows as a bulge on the under front end of the down and top tubes.
You could have bought scrap metal.. if so..

Why not run a 700c front? A replacement should then be easier to find... you can run the two different tires and still carry one spare tube, as the tube will fit both. The Atala I did for my father is 700C rear and 27" front, running matching panaracers I think.

Or, f you'e shelling out a bunch of $$$ for that ebay replacement fork, I bet yo could recoup most of that $$$ if he handling is off after the install when you sell it on. Sell it for $20 less and consider it an experiment...
