Thomas Frischknecht is a legend in XC racing. He's been on the circuit for years, won World Championships, World Cups and all sorts of other stuff and is still racing at the top level today. He has a great deal of input into the designs of products from his main equipment sponsors Scott and Ritchey, which brings us neatly to his bike...

At the heart of the bike is Scott's ultralight Spark carbon fibre FS frame delivering 110mm of travel. This frame is the version with the integrated seat post design - the "post" is part of the frame, with a clamp-on seat bracket at the top. It's lighter and stiffer than a conventional setup, but obviously less versatile. That's not a consideration for elite-level XC racing, though.

There's obviously a lot of gear from sponsor Ritchey on this bike - seat bracket, double-ring chainset, and carbon fibre headset, bar, stem and bar ends. Forks are from DT, and the remote lockout lever mirrors the Spark's remote shock travel adjust/lockout control on the other side of the bars. SRAM's X0 equipment does the shifting, although Frischi eschews trigger shifters in favour of Gripshift units.

Frischknecht's wheels are particularly interesting. He runs a unique wheelset using Ritchey deep-section 650C time-trial/triathlon rims and custom-made Dugast tubular tyres with Ritchey tread patterns. The rim diameter is slightly bigger than conventional MTB rims, but the overall wheel size with the custom tyres is about the same.

We don't actually know what the complete bike weighs - Frishcknecht's first Spark came in at 9.9kg (21.8lb) and that was the conventional frame without the integrated seat tube. It also had Fox forks rather than DT, and some of the other components (saddle, cranks, bar/stem) have got lighter.

Over to you

Got an interesting bike that you’d like to tell the world (or that subset of the world that reads BM) about? We’re not too bothered whether it’s singlespeed, geared, hardtail, rigid, FS or whatever – it just has to be something unique. We’re looking for bikes that have had a lot of time invested in them by their owners. Send us a pic and some words about what it is and why it’s like that and we’ll run the best ones here...

Which fork from DT?

Here is an article about a very light xc racing machine custom made to suit a legendary rider, and the info looks like it involved looking closely at the photo and going "Oooh its a spark ltd,........ is that a dt fork? Yes? Custom wheels yum. I wonder if I should find out a bit more?....... Nah that'll do."

I blame the parents.

the fork's an xrc100, as is evident by looking at it

Those are the first tubs I've seen on an MTB since Hutchinson's tubeless tubs in the mid 90s. The latex repair 'bombe' lacked the crystals in Stan's so puntures didn't seal very well and the tyre was effectively scrap after the first thorn.

Yeah, 'cos you can tell, for example, that they're 650C rims and custom tyres just by looking at the picture...

Anyway, it's better than it was, the first draft said "Pace forks". Doh!

i must say, the wheels are without a doubt the ugliest things i've ever seen. and i've seen the camo sun mtx'es, with green michelins, with a gold pro2...

The word "Dugast" is beautiful to my eyes.
Posted: 13/09/2007 14:08

Are the tyre sidewalls made out of streaky bacon rind?
Posted: 13/09/2007 14:10

Ugly, in what way? I never get why people moan about componenets being ugly - they're designed to be covered in mud in no time at all.  An they're not covered in loads of horrible graphics (such as the camo design you mention).

The wheels are certainly the most interesting part on that bike for me.  Certainly something a bit different than the norm. I wonder how much those Dugast tyres cost.


Posted: 13/09/2007 14:12

Dugast off the peg are about 80 euros a pop or so. Bespoke ones? Who knows, but I'd say around 150 euros wouldn't be too off.

tbh, i wasn't aware of any particular problem using clinchers on a mtb, it seems to me they were solving a problem that didn't exist by going tubs
Posted: 13/09/2007 17:53

It was Michelin that solved the problem that didn't exist by inventing the clincher. Tubs came first!
Posted: 13/09/2007 18:26

Tubs are lighter, if that's a 650c time trial wheelset it's gonna be chuffing light, they also roll better etc etc.

 Travis Brown rode some Bontrager Race X Lite Aero carbon wheels a couple of years ago with tubs on, same deal, your choice of tread on a 650c tub carcass.
