Try not to be stupid this time guys.

Discussion forum for weight-conscious gravity racers. Post and talk about light-weight DH/4X parts, etc.
I will edit this post to include all of the parts weights and resources. If you weight shit, try to put it all in one handy album.
If you have a resource you think may be front-page-worthy, please include a link to your specific post (if I don't see it in time, I have no clue how to generate the specific URL). Same goes for bikechecks.

What, do you think, is the least amount of travel that DH riders can get away with? Has anyone raced a single crown on the WC circuit?

Posted: Jun 18, 2009 at 13:42 Quote
Totem would cope probably, but I don't know why you would favour a single crown when racing WC.

Posted: Jun 18, 2009 at 13:43 Quote
One of the Intense riders I believe, rode with an SC Manitou for a couple races.

Commencal got away with 7, though have up'ped it.....I assume because they were just getting away with 7.

On a personal note, I've jumped up in weight.....Gustavs are back on and the Ultimates are on the XC bike.

Posted: Jun 18, 2009 at 13:44 Quote
I lack exact numbers but aren't Boxxers and Totems roughly the same height, the Boxxer being lighter and with an inch more travel? Also don't see the point at the highest level of DH racing.

Posted: Jun 18, 2009 at 13:45 Quote
Can't remember which one (think it's the Boxxers) have a 3mm higher a/c.

Posted: Jun 18, 2009 at 13:45 Quote
Boxxer is 3mm higher A-T-C.

Posted: Jun 18, 2009 at 13:48 Quote
Just watched a video on Freecaaster on commencal, theyve supposedly cut 2KG off the new Supreme DH full bike.

Thats a seriously big saving!

Posted: Jun 18, 2009 at 13:48 Quote
Interesting. I wouldn't think there would be much of a benefit.

Opinions on Chub hubs? What's the weight on those like?

Posted: Jun 18, 2009 at 13:49 Quote
Weren't the Atherton's Supreme DH's sitting at around 41/42lbs though?

Posted: Jun 18, 2009 at 13:51 Quote
Yes, but the stock supreme DH was sitting at something like 45-46, specced with 888RC3 WC's etc, it appears to now be running boxxer WC's, and get this, a Van R rear shock? they say its all about reliability, i can see their point, but im sure there wilkl be a fuss.

I think Kovarik rode a Manitou Travis at Willigen WC a few years back. it's in Earthed 4.

Cutting 4 pounds off a stock Commencal from this year most likely isn't that hard. They're around 45 stock this year.....some easy changes could do it.


Edit: and muttley beat me to it.

Take care of good shocks and the reliability will come.

Yeah, he was on a socom with travis singles, but willingen doesnt exactly warrant a WC-Mobile.
