The Original Thorpy Posted October 31, 2007 Report Share Posted October 31, 2007 Right ive not been on here for a fair old while and i cant seem to be able to use my old account so im having to post this in here. Basically im in my final year at Uni. studying a BSc (hons) degree in CAD. And i need some facts from you the riders.Im currently in the research phase of the project, which is the Design and FEA of a Bicycle Hub (rear) specifically designed for Biketrials. So i just need a some feed back on what your perfect hub would be? Engagements?Weight?Materials?Cost?Asthetics?Fingerscrossed all you nice chaps will give me lots of feedback on what makes the perfect Biketrials hub so i can get some concepts on the way.If possible could someone make this a sticky or even upgrade my account so i can get the opinion of the riders that have been "around a while" as i cant imagine them coming in here all that often.Regards, Richard Quote Link to comment Share on other sites More sharing options...
ZeroMatt Posted October 31, 2007 Report Share Posted October 31, 2007 Would be more useful if you gave us some choices seeing as the perfect hub would have infinite engagements 0 weight e.t.c. which is somewhat unrealistic. Quote Link to comment Share on other sites More sharing options...
The Original Thorpy Posted October 31, 2007 Author Report Share Posted October 31, 2007 Fair point, i have an idea in my head for a hub with 300+ points of engagement but ive not looked into it massively as its complex and quite bulky so the figure could and probably is wrong. I would give more idea but i just dont have any at the moment. Im also tempted to look into forging the hubshell instead of CNC machining to increase strenght but its not exactly a nice finish. again im not sure its possible.seems like im digging a hole hereProbably not much help.

The Riddlers Posted October 31, 2007 Report Share Posted October 31, 2007 (edited) Personally, I dont give a shit what somethings made from, or looks like if its the dogs bollocks.As for weight, well as light as possible really, but given what your after, its not gonna be that light, so to me, its weight wouldnt be an issue (unless its MEGA heavy)Engagements...well, as many as possible of course!And cost..well, people will pay the money if a bit of kit is proven to be good...look at stuff like Chris Kinf hubs....they can go well over £200 squid and people buy them day in day out!Sounds to me like you need to build a prototype or even get it down on paper then approach us saying its got blah blah....is this a good price for it?!Hope that helps Edited October 31, 2007 by The Riddlers Quote Link to comment Share on other sites More sharing options...

scousertrials Posted November 1, 2007 Report Share Posted November 1, 2007 Can't you just do a bit of contemporary comparative analysis. That should answer all the aforementioned questions. Quote Link to comment Share on other sites More sharing options...
Bionic Balls Posted November 1, 2007 Report Share Posted November 1, 2007 tis all so vague! you clearly aren't an engineer yet read about material selection and it should answer all of your questions...make simple mechanical models of the stresses on a hub and find a density/weight/cost factor...book by mr.ashby will tell you everything you could want to know..

N.Wood Posted November 1, 2007 Report Share Posted November 1, 2007 One thing to add - Don't worry if it looks like shit, as long as it works people will buy it.Also, concentrate on making something damn strong and reliable, as I and many others would prefere something that i could trust, and would give up the extra 200-300 grammes for that security.

Vee Posted November 1, 2007 Report Share Posted November 1, 2007 it cant skip either! theres no point making 300+ engagements if its gunna skip 500 of them and yes it could skip 500 of them lolstrong very reliable and more than 72 engements would be mint Quote Link to comment Share on other sites More sharing options...
