I need a replacement pair of forks for my ageing 'Cross bike. Apparently, straight-steerer-1 1/8", 400mm, QR carbon forks with a disc mount are like hen's teeth. Then these pop up on the eBay and seem to tick all my boxes. Even the steerer's long enough. Brilliant. BUT....
Is there something wacky about them, they being Cannonade? I don't know much about the brand ever since an unfortunate F600 acquisition many years ago. *shudders*
Anyways, the seller is next-to-useless and just sends me photographs when I ask him questions about the diameter of the steerer.
So is this steerer straight, or is it tapering to 1 1/4" to 1 1/8"? And has he left a crown-race on there, or are these specific to an integral headset?
In short, can I use them on an and old-skool, 10-year-old Uncle John frame with an old-skool headset?
Your hive-mind wisdom would be much appreciated.
unless the perspective is really weird I'd say that is a straight 1 1/8 steerer and yes there is a crown race on it.
I'd have gone with joemmo but I've no idea what the big silver bit at the bottom is, some sort of sleeve for a headshok?
no it's just a sleeve to make it easier to machine an accurate seat for the crown race, some carbon forks have them, some just fit straight onto carbon.
Exotic carbon forks are exactly what you want.
Thats a standard 1 1/8 with the crown race on by the looks of it as mentioned. A 1 1/8 runs a 30mm diameter at the base (hence its wider than 1 1/8) so needs to flair out a bit.
Ah fair do, not seen one of those before.
I think that's an alloy steerer though looking at the cut end, and at a guess the sleeve is about 1mm thick (so 2mm diameter) then looks flared at the base which would make it really quite wide for a 1.125 steerer (crown race seat is 30mm so 1.4mm thicker than the steerer nominal).
Any how - I'm probably wrong just looks odd. (My very bad scaling from the photo says 1.7mm for the sleeve based on 1.125 steerer, given the normal base flare that would be about spot on for a 1.25 crown race seat. Giant Overdrive adapter?)
And like I say: Cannondale do do 1 1/8" to 1/1/4" steerers on their CX bikes. But maybe only recent ones? These forks are 2013.
I had the same thought on seeing the photo, looks like a 1 1/8th top and 1 1/4 bottom. Had the same with a friend's commuter when his headset seized solid.
I've been looking for something similar recently. I can't give you any input on the one's you're looking at here, but can suggest these if you end up looking for something new (the latter may have poor clearance though, I'm not sure)

*2015, not 2013. Obviously.

That sleeve is way more than 30mm OD at the base if the rest of the steerer is 28.6mm.
I could be wrong but to me that looks like a 1-1/8th steerer with a sleeve (bonded/pressed on?) at the bottom to accomodate either a 1-1/2" or 1-1/4" lower race, i.e. a quick and dirty way to adapt a 1-1/8" fork to suit Tapered headsets in production, without having to actually produce a whole new tapered steerer...
Or is that a crazy idea?
Either way can that sleeve be removed like a normal race would be or not?

Unknown. But I don't want to buy them and then find out I can't 🙂
