DownhillingKing Posted September 22, 2009 Share Sweet would love to see it when it's done! Link to comment Share on other sites More sharing options...
Artorius Posted September 22, 2009 Share Here is a link for you Bakkies. Its a helluva long thread but you should get some good info. http://www.pinkbike.com/forum/listcomments/?threadid=39840 Good luck with the build.

Slaya Posted September 22, 2009 Share So where exactly would this fit into the grand scheme of things??? SHEEEZZZZZ!!!!!! Link to comment Share on other sites More sharing options...
Bakkies Posted September 22, 2009 Share thanks but if my design works, you'll be seing the next sa brand, dh bike. The frame is aimed at between 3.5kg - 4kg. 210mm rear wheel travel. a very low leaverage ratio on the initial shock stroke and ramps up to get a very soft bottom out.

DownhillingKing Posted September 22, 2009 Share Dam riding that you would have to have alot of faith in the person steering!!! Here is the frame I would like to build they are really really light well so I have heard! Link to comment Share on other sites More sharing options...
Bakkies Posted September 22, 2009 Share UPDATE: REAR TRIANGLE INCLUDED!!!! WHAT DO YOU THINK??? Link to comment Share on other sites More sharing options...
DownhillingKing Posted September 22, 2009 Share Could you not get away with using just the light grey pivot peice Link to comment Share on other sites More sharing options...
Capricorn Posted September 22, 2009 Share Bakkies: what's the kinematics of your linkage? Do you have some software that shows the travel? or even a rough diagram? Link to comment Share on other sites More sharing options...

Bakkies Posted September 23, 2009 Share Bakkies: what's the kinematics of your linkage? Do you have some software that shows the travel? or even a rough diagram? I wrote my own excel program with all the motions kinematics, leaverage ratios and so forth. My cad is a freeware and is limited. but i'm saving up for a full package to do a finite element analysis. The bike will be world class. I've already designed the welding procedures and manufacturing specs. these pics are some of my earlier designs. i'm testing weather the design looks good enough to market.

Capricorn Posted September 23, 2009 Share if it's a Dh bike, then it's more important how it works than how it looks. Form will follow function. but again, what's the intended kinematics of your suspension, especially the rear? i doubt it's a trade secret cos up and back, or just up, are common nouns, and frankly, probably all useful kinematics have been explored and used on past and current frames.I'm simply interested in the type of setup one can expect from the way you've decided your rear suspension. From which current suspension design do you take your design cue from? horst linkage etc...? Link to comment Share on other sites More sharing options...

Bakkies Posted September 23, 2009 Share Capricorn: I agree function over fancy looks and no design is unique but simple alterations to the geometry can deliver great results. A huge case study has been done to select the best design.Before i designed the frame and looks, i designed the suspension so function first. The rear wheel path will be allot like the vvp from santcruz. a intial low leaverage ratio and high ratio at the end of stroke. Link to comment Share on other sites More sharing options...
Bakkies Posted September 23, 2009 Share thanks for the more dirt link. it is awesome Link to comment Share on other sites More sharing options...
DownhillingKing Posted September 23, 2009 Share Can't believe you guys never heard of it! So Bakkies if you paint the frame in red like a Ferrari with white writing and it has 8" or more travel and it turns out to be a great success I would be very keen how much would you sell a Frame for?
