Cannondale fork now muerte. Help!

My biggest worry about our favorite old Cannondale Tandem finally came to pass. After 20 years of great service and many fun miles, I found a severe crack in the 1 inch steerer tube where it meets the crown of the fork..…found it right where you would expect to find a fatigue or stress fracture.

Despite having another newer Tandem, this old Cannondale remains our favorite. It is the far more versatile of the two as it easily converts from road trim to touring duties and/or light offroad/rail trail applications. We’ve upgraded every component on it in recent years except for the original eccentric and the now newly departed fork. We’re not ready to part with this old friend so we’re motivated to find a proper replacement fork. So far we have struck out completely.

The challenge is the fact that this vintage C’dale has a 1 inch steerer tube not the more conventional 1 1/8 “.

Calls to my LBS and a distant Cannondale shop produced no leads and little help except for a non-tandem rated possibility that I don’t feel good about. Also looked at the usual Tandem vendor web sites but found nothing. We frequently ride on very rough paved roads as well as occasional dirt roads/ trails that do stress the fork significantly, so I can not bring myself to trust a cross fork or anything less than a proper Tandem one.

Does anyone have a suggestion on where I might find a new, tandem fork with a 1 inch threaded steerer tube compatible with the first generation Cannodale Tandems circa 1990-91?....or….has anyone had a custom fork made? Where?

Thanks…Bill J

See if you can speak to Dennis Bushnell at R&E Cycles... he has the materials and skill to replicate just about any type of fork.

Steve Rex and a host of other custom tandem builders could also weld-up a replacement to the same basic specs once they had your old fork in hand.

Can't tell if this is up to tandem standards, but it's built for cyclocross + disc brake ... a killer deal at $110 + 20% off + free shipping: http://www.nashbar.com/bikes//Produc...2_175019_-1___

Would recommend asking Nashbar who's the supplier, and then try to contact them directly to ask questions.

I have the Nashbar fork on my tourer. It's excellent and does everything I want it to do. Is it strong enough for a tandem? Couldn't say...

You might try contacting Rick Jorgensen at Tango. However, he is currently drilling out the head tube of my 21-year-old rather than fabricating a new one incher. Good luck.

a google search pulled this up, they have a crmo steerer with a carbon fork for CX that would fit, never heard of the company though.

Still I'd trust it more than nashbar : P
