Tandem carbon fork with 1" steerer

Quoted message said:

Does anyone make a carbon fork with 1" steerer for a tandem bike?
Note, the 1" steerer should be steel or metal, not carbon. Threaded or
threadless, does not matter. Cantilever bosses wanted, although not
absolutely necessary.

Or maybe the question should be will any carbon fork with a 1" steerer
work in a tandem? Do carbon forks need to be tandem specific or will
any work safely?

The fork would go on the first production year of a Cannondale tandem.
They came with 1" forks.

I seem to recall from a quarterly I get from Santana that they use some
sort of beefy Alpha Q full carbon fork. Decidedly not 1" though.

There are beefy carbon cross canti forks out there that probably would
fill the bill, but I think most I have seen have alloy steerers with
carbon legs.

Why screw around for 300 gms?

frames and is having a pot and kettle moment.

Here is the fork (and possibly others) that might work for you:

D'oh! I suppose I should have read more closely.

A buddy of mine came in with a fork for his new custom frame... full carbon,
and the steerer was probably around 2 feet long and at least 5mm thick! I
think it was the q-carbon one that d'ohboy mentioned. We had to use a
breaker bar in addition to the headset setter to get that sucker on there.

Because the man who owns the tandem thinks the original steel fork is
harsh riding and has decided he wants a carbon fork. As simple as
that.

I don't think a 1" CF fork would be safe for a tandem. BTW, I have
the same model Cannondale Road Tandem. The fork is fine. The weight
of the fork will be the only difference in ride. A CF fork would
likely be stiffer. You could upgrade to a KHS 7005 Aluminum tandem
frame and get more weight savings.

Well I think you have a problem Dr Ruth may be able to help with.

Why would a 1" carbon fork with a steel or metal steerer be any more
unsafe than any other fork with a metal steerer. As I said in my post
"Note, the 1" steerer should be steel or metal, not carbon." I doubt
the fork blades on 1" carbon forks are any spindlier than the fork
blades on 1.125" or 1.25" carbon forks for tandems. Reynolds, WoundUp,
True Temper all make carbon forks.

I'm sure it is. But the person who owns the bike wants a carbon fork.
Simple as that. Want is the only factor.

Woundup makes one. Threadless steel steerer with canti bosses. I don't
have any experience with it. There are probably others.

Pretty much any fork on a tandem should be tandem-specific or
"tandem-rated." Tandem loads are pretty crazy and potentially
overloaded forks are about the last thing you want to mess around with.
That said, the industry is stupid and who knows how much thought goes
into it when a company decides to call something tandem-rated.

Because one of the potential failure points - in fact, the worst
possible failure point - is where the steerer is bonded to the crown?

I have a couple of bikes with aftermarket carbon forks, mainly because
the cost of going threadless was pretty much the same with a new steerer
and a respray or a carbon fork. It does seem a bit Heath Robinson [1]
to have a chromoly steerer glued to an aluminium crown glued to carbon
blades glued to aluminium dropouts, but hey, it looks cool ;-)

Although there are plenty of 1 inch carbon forks ( Profile
$199, threaded add upcharge) and 1 inch cantilever carbon
forks (IRD) I would specifically ask the manufacturer about
the application before installing one on a tandem.

BTW, why?

Because the tandems owner thinks the original steel fork rides harsh
and wants a carbon fork. Want. Not need. Not logical, etc. Just
want. And he has the money to turn his want into reality if there is a
1" steerer tandem specific fork available. It appears WoundUp does
make its tandem specific fork with a 1" steel steerer. Special order.

Ah, our nearest equivalent sounds like Rube Goldberg.

In Britain, such a device would be called a Heath Robinson contraption,
after the British cartoonist who also drew fantastic comic machinery,
in his case tended by bespectacled men in overalls. See also Roland
Emett, who created many actual working machines of this type, such as
the Breakfast Machine in the film Chitty Chitty Bang Bang.

You REALLY want a tandem specific fork that can take the loads. I have two
acquaintances that have broken forks catastrophically on tandems, with forks
that were under-capable for the duty at hand. Believe me when I that say
it's not pretty when it's over!
