Road forks with 1.25" steerer?

[oliver1850]

Came across a Cannondale road frame that was made for a threadless 1 1/4" fork. Was surprised to discover that 1 1/4" road forks existed. Are there any other 1 1/4" road forks out there besides the AL fork that Cannondale supplied?

1 1/4" tapered still exists, I think

Can you not use a 1-1/8" or a 1-1/4 taper with a reducer headset? I would imagine that a straight 1-1/4" road fork is not easy to find.

It probably is a tapered steerer no? There are no 1-1/4 stems are there?

Canyon and Giant both specced 1.25" steerers for a while, iirc. Not sure if they still do. There are 1.25" stems out there. Ritchey does some.

Was the Cannondale 1-1/4 fork not with a straight steerer? That would prevent you from using any of the modern Giant and Canyon forks as they have a 1.5" integrated crown.

I'm thinking an adapter to a 1-1/8 fork might be the only option here.

Correct re: Canyon and Giant. ZIPP makes a stem that'll work with either 1.25 or 1.125.

Nevermind i missunderstood you.

I have a '92 or '93 Santana with 1.25" threaded fork. It takes a quill type stem.

Get the Problem Solvers headtube reducer..use a 1/18nch HS.

Thanks for the replies. The original fork was straight 1 1/4" and the bike came with a threadless Control Tech stem. Earlier (1993) 1 1/4" forks were threaded, not the most durable setup with an AL steerer I'd guess.

The headset adapters may be the best option. I don't think it would be be too noticeable to step down to 1.125", and the Control Tech stem will be easier to locate in that size. Owner is trying to build the bike as it was when it was new, but may have to compromise on the fork.

The 1 1/4" headset standard was called the "Evolution" headset. It came out not long after the 1 1/8" headset, and only lasted a few years (I guess nobody saw the point of it). It was originally available as threaded, but later was available as threadless.

Later, when bike designers were looking to up-size steerers from 1 1/8", they went straight to 1 1/2" - probably because they didn't want to acknowledge the failure of the 1 1/4" standard.

I remember "de-evolution" headsets, and myself used reducer cups top and bottom on an Alpinestars MTB frame that I had.

I think it was Manitou who brought forth a larger-yet steerer when they introduced single-crown forks meant to compete with downhill-specific dual-crown forks. I recall at the time that at least one of Marzocchi's marketing people went on record lambasting the "needless" over-sizing of existing 1-1/8" steerers by a fork maker with "no credibility" in the world of downhill forks.

The adapters to use 9/8" steerer headsets are a great way to go for such an animal, but when I read the above, I rather interpret it as:

"Owner has impractical desire to assemble the frame into a bike as it was when new, but doesn't have something as critical to such an endeavor as an original fork."

90% of the "talking points" of such a build would be the unusual and "very light for the time period" metal fork. Without that? Maybe buy the problem solvers piece and put it AND that frame back in a shop corner until someone the owner knows needs a bargain road frame?

I'm not trying to talk you out of a project, but without the Sub1 fork, there are, I'd reckon, other more attractive projects.
