found my dads old peracini frame in the attic the other day and have decided to build it up, only problem is it's built to fit a 1" steerer tube. I have the old threaded one but really don't want to put an old style threaded headset or those those cone-clamp-stem thingys on there. I thought about just trying to clamp a new style stem over the threaded portion of the steerer tube but there's just not enough room to do it, what with the headset and all. Anyone know a way around this? Or somewhere that sells 1"threadless forks. UK preferably. cheers.

Not UK, but I have this on my old steelie with a Ritchey threadless headset. Over 10,000KMS and no issues at all.

UK, you'll also need a shim to use a 1 1/8 stem on a 1 inch fork.

I personally used this for my stem shim;

funny, i am building one of my dads frames that spent years in the attic. i opted to use an easton full carbon fork. the weight reduction over the original steel fork is, well, considerable.

Or you could just use a threadless stem adapter.

Torelli makes steel and carbon threadless forks for 1" or 1 1/8". Various fork options on the left.

Finding a seller can be tricky. Someone sells a lot of Torelli stuff new on ebay.
I found some Torelli parts here too, but haven't made any purchases from this seller.

there are not many 1in threadless stems out there but there are some nice ones:

3ttt mutant
cinelli grammo
cinelli sesamo
cinelli alter
kelly chromoly

you can also use a 1 1/8th stem with a shim (as noted above)

I've been considering a carbon fork for my steel 2000 Marin San Marino (it was spec'd with a 1" steel threadless fork). Here's one listed on ebay:

The bike would lose at least a pound. I'm currently running a 1-1/8" stem with a shim, no issues.

I have a Bontrager carbon/alloy steerer aero fork that just collecting dust if you're interested. It's 1" threadless.

I went with Reynolds Ouzi Pro a few years ago along with a Chris King headset. I think the entire switch saved me 2 lbs.

The Kelly stems are quite nice and match well with steel frames. 1" and have been going for dirt cheap on ebay.

On this page, click on 1" threadless.

i ordered one of these kelly stems after seeing that picture.

Do you have the correct headset as well?

Have you posted full pictures of this iteration of the bike anywhere? I'd like to see them. BTW, where did you source the EC90? I tried to find one, but had no luck whatsoever.

One thing I found while looking for a 1" threadless fork is that older frames took longer axle-to-crown lengths than what is readily available. Many of the current 1" forks are in the 365mm range (for track and fixie) but the older forks were often 372+. Reynolds Ouzo and Alpha-Q forks were in the 371-372mm range and a good fit.

As far as I've seen the Ritchey Carbon Comp is the best fork for the money. It is definitely the lightest out of all of the 1" threadless carbon forks I've seen. The Columbus Minimal fork on the Torelli sight looks intriguing but no weight is given, and the retail price is double that of the Ritchey fork. Also, a trusted bike shop mechanic that i know told me to stay away from 1" carbon steerer tubes.

funny you mention that. the original plan was to use the OEM steel yokota fork and then contact you about this one. i received the EC90 with my tommasini in addition to the original steel fork.

i would love to trade it even over for a 1in wound up fork (the ec90 is lighter but the wound up would fit the look better)

i have not posted full pictures yet. i need to pick up a few odds and ends. expect to see full body shots (sans saddle, bar tape, and chain) this weekend. complete pictures are due in about a week. at that time i will post it in every applicable thread i can find. you are bound to see it

true. i didnt measure, but it is noticeable that the EC90 is shorter than stock. fortunately my frame was somewhat relaxed. to make manners worse, it takes an odd seatpost size so i am currently stuck with a 0 setback post and the short top tube necessitates a 140mm stem. im not sure what to expect from it. the frame will have aggressive geometry and a lot of weight up front. combine that with the 42/53 11-21 gearing and it will be an odd ride. fortunately it was cheap and more of a design project than an everyday bike.

i would be surprised if the ritchey was lighter than a 1in full carbon EC90sl. i think mine came in well below 300g w/ a very long steerer.

i would rather have an aluminum steerer but im not afraid to ride the carbon one. just follow the directions and it should be fine.
