Phil Wood Shows Converted Santa Cruz V10 DH Fat Bike – Plus New Track Crankset & Seat Collars

2013 Phil-Wood Santa Cruz V10 fat tire snow bike conversion

At first glance, I thought this was a gimmick to draw attention. A helluva gimmick, but a gimmick nonetheless. Turns out it’s quite real, even if it is just an early version of a conversion kit.

Phil Wood, with a little help from Jay Jeremy Sycip, built a functioning set of parts to turn Santa Cruz’s V10 downhill mountain bike into a fat tired snow bike. It uses adapters at the bottom bracket, a massive rear hub, altered Manitou Dorado and more to make it happen.

They also had new track cranks and seat collars. Bike and parts pics, details and suspension of practicality below…

The 135mm front hub required new crowns for the Manitou Dorado inverted fork. It’s a 29er Dorado with a stopper inside to limit travel to 6″.

It has a 185mm wide rear hub, which is 15mm wider than a standard snow bike hub. They make the hubs and the axles and just made a longer axle. The rear wheel is a Surly that’s designed to be laced with 32 spokes. They laced two sets of holes for a 64 spoke build to make it as stiff and strong as possible since weight wasn’t as much of a concern. It’s such a big wheel they had to use a motorcycle truing stand to build the wheel!

They made a spacer kit to spread the crankset out and get the clearance and chain line right.

They’re still fine tuning the concept and will show an even higher end version at Interbike. Sycip rear end is made by Jeremy SyCip to fit Santa Cruz’s pivot position specs. They’ll lengthen the chainstays a bit more to fit a knobbier tire. Rear end travel is 8″.

As much as anything, this is likely a design exercise to see what’s possible and ferret out interest. Want your own? Let ’em know.

Wound be sweet so I can do bigger ones of these….
All that custom work looks $$$$, awesome way to showcase what is possible. Bikes are way too fun to just stagnate design and usability.

I want one of these kits after they figure it all out. I have one request, I have to be able to bolt on an Ego Kit! ( ) . This would then be my ultimate fun machine when I want to have lots of Crazy downhill fun!!!! I have a 2003 Yeti ASX now that’s waiting patiently for it’s Ego Kit upgrade but heck this combo could be even better.

In your opening paragraph you mention Jay Sycip, Jeremey’s brother. To the best of my knowledge only Jeremy worked on the rear end.

It sounds funny to say out loud but that seat collar is gorgeous in the polished finish.

A big tired V10 is cool I guess from a fabrication exercise standpoint, but seems a bit like a answer to a question that nobody asked.

Stephan – good catch, you’re right, it’s Jeremy. Thanks!

Not trying to be a d!ck, but when you hover over any of the pics, the caption says “Paul Components…”

those seat collars are kind of a fail. Why isn’t the silver one engraved and filled with red, like EVERY other PW component?

Tyler (Editor) - 09/07/12 - 12:04pm

Pat – oops, fixed that too. Always get those two confused by name, both make great stuff.

The 29er Dorado has 175mm of travel. A bit more than 6″.

Andrew F - 09/07/12 - 2:59pm

No fender and rack mounts?! How the heck am I suppose to do multi-day snow downhilling bike packing?

Just kidding – that thing is rad.

Gillis - 09/07/12 - 3:30pm

mtbrider, it says that a limiter was installed to keep the travel at 6″. Otherwise the wheel would hit the crown, resulting in a bad ending.
