As the title implies,

Here is a good implementation by a UK custom builder.

Interesting thing is the no small print warranty/guarantee.

I notice that it's supposed to have a risse rear end, I see a fox shock on the ones in the pictures. Other than the BB looking a little high, which may be an illusion it looks like a pretty well built and well thought out bike.

 

[math2014]

Yep it looks nice and simple... T45 steel which is supposedly stronger than 4130, fully customized, and with a new custom T45 curtis rear end in the pipeline....

At last something good to be had from living in England

holy skyscraper, batman:

ive ridden that, it heavy, but it rides really really well.

 

[narlus]

is it heavy? the claimed frame weight on the site is 5 lb 7oz (w/o shock). even w/ a steel-sprung shock, that's gotta be easily under 10, which would make it on the light side of DH frames.

they are referring to the risse style rearend of the bike not the shocks
its similar to the lassen and the remec bikes

 

[wysiwyg]

it was heavy to me, not as heavy as that damned demo9 tho.

im a HT boy, so everything is heavy

it was plush thats for sure, and it eats drops for dinner, cos thats mainly what Jim does on it.

I didn't realize that was called a risse style rear end, I'd have called it a non-horst link 4 bar, linkage actuated single pivot or some other generic term. Symmantecs aside it's a clean looking bike.

 

[biggins]

kinda tall standover height though. also is it available in rootbeer?

That isn't risse style, that is a risse rear end. I know I helped the development on it when i raced at risse. They license them to a few companies now. Very stiff, modular and surprisingly, not as heavy as a boat anchor. The machine work is top notch, but replace the stock hardware as it is heavy.

It's a Risse rear end because Risse built it. They sell a modular faux bar rear end. http://www.risseracing.com/Products/Bikes/rear.html

edit: need to learn to type faster

 

[math2014]

all sounds good to me .

I hope the Risse rear end is at par with the durability of the front triangle.

BTW Curtis is now doing a version with a much lower standover than the bike depicted at the pic above.

 

[TheInedibleHulk]

The MkII front end in the one-off section looks much sexier and solves the nut cruncher toptube problem. I also dig the hardtails, especailly the custom trials bike.

I bet you that quoted weight is probably only for the main frame and not the rear end stays etc.

holy skyscraper, batman

I guess they like high BB's in the UK. New Muddy Fox for '05...

 

[biggins]

damn how much does that muddyfox thing cost?in us dollars

 

[UiUiUiUi]

that muddy fox thing looks good...
it seems it has an adjustable shockmount.
so hopefully you can lower it quite a bit.

 

[Enduro]

Nearly 8 grand. It's got 11 inches of travel btw! 5:1 leverage ratio...

ouch!!!

WHY?

 

[math2014]

yay another great muddy fox design...

Hairy Gary has been making steel DH bikes for years.

 

[JRogers]

Exactly what I was thinking. Under 6 lbs w/o shock seems really light for a steel FS DH frame.

yeah there's another builder i've seen posted on RM that makes high middle single pivot DH rigs that were affordable, although ugly...

I'd get one of those over the HG or this any day....just not a big fan of risse's work, nor hokey weight claims.

 

[Duzitall]

Looks more like 6 kilos instead of pounds

chris

 

[RaID]

not exactly the prettiest thing in the world

looks like it would do the job though

 

[TheInedibleHulk]

Looks like an old school M1 that someone bought the wrong shock for.

 

[Bulldog]

Why can't I see any of the pictures? (have shut off my firewall/popup protection already)...

 

[BikeFan84]

not really into that, like the hardtails though

 

[scottishmark]

much more like it............

 

[scottishmark]

Nearly 8 grand. It's got 11 inches of travel btw! 5:1 leverage ratio...

where'd you get that from? says 225mm shock on the site, not 2.25inches

 

[mr.terrible]

much more like it............

Very neat looking indeed, just like the hardtails. This is the low-standover one I presume.

 

[Glennder!!]

steel bkes just look so sexy.

 

[Enduro]

Sorry, my bad...

 

[konabiker]

"custom risse rear end"

 

[zedro]

definitly much better. The other high top tube design really bugged me.

 

[math2014]

"custom risse rear end"

huh?

smoking?

BTW the mkII Thumpercross looks veeery good, mate this with the new customised steel rear end from Curtis that you ll be bombing for maaaaaany years...

I'd take a FULL 4 YEAR WARRANTY over a lifetime warranty any day.

unhappy with the warranty offerings of spesh?

probably doesnt understand the definition of 'warranty'....many don't.
