looking at this chart,80 to 93 are the winners for brake pads in general,with 85/maybe 90 beeing on top,as its mixing most of the properties. i.e.sticky like rubber would be,shear resistant like pu,wear resistant like plastics just a thought

http://en.wikipedia.org/wiki/Shore_durometer i think thats helpful,i did read it and cannot reflect it in here lol ithink its different measuring scales to determine the properties edit:wow this ones understandable!

Hardness Shore Scale Description 35 A Rubber band 50 A Inner tubes 60 A PVC hose 70 A Car tyre treads 95 A Fork lift truck tyres 60 D Polyethylene rigid plastic 80 D Nylon rigid plastic yeah,and interesting,too

something between 80 and 85 (both shore a)would be good i guess.... any harder would be like a plastic backing,and under 70 we´re in pencil eraser territory lol edit:interesting find:http://www.alibaba.com/product-gs/800511059/Hardess_Shore_40_80A_Pure_Gum.html check the chart below,tensile strengths and co edit 2:oh,seen its gummy rubber will continue searching

should be pretty hard (t)hat. i think cutting or grinding it to shape would be no problem though

thought so,got exactly those yellow pads in my hand right now and theyre like a skateboard wheel,pretty hard,fast rebound. why do you think it isnt the durometer,out of interest?

thats from ashima,hmmm,is the number the hardness?

thats what i´m talking about! only cheaper haha. joking aside,would be great to get some info what exact properties established pads have,too sad noone can find out...

come on,its not a bad idea at all. and i mentioned it being old :wink2:

googled a lot and found some old topics involving ali c using urethane from ebay,if i remember correctly. i want to get some urethane sheet from a company that produces industrial grade rubbers and stuff,making my own refills,so i´m asking about what durometer/material description etc i should look for. thought about 85 shore a... from a sheet for 25 euro one could make something like 100 sets of pads,how awesome would that be? cheers for comments and opinions,and especially for advice!

what pedals are they?need some fluo ones for my marino

you see the freewheel,its a 16t,has a certain diameter... :wink2:

i´ve ridden both the 24 and the 26 version of this frame with rigid setups on a few occasions,those frames are serious fun on speed lines,on the rear should be another thing. looks great though

argh why did i come in here?

at the end you need only the hub flanges hole circle diameter and the rims inner diameter from valve hole to opposite side,plus 2x wall thickness of the rim and i could tell you... ...or adam,of course.

that racing track shot looks awesome to me.

youre right,adam. had to have a coffee to get it,posting without beeing fully awake haha 24:18=1.333333 18:12=1.5 with this wheelsize it makes a difference really

i´m far away of beeing a photographer,i just take shots here and there with my cheap digicam with 14mp,but i´d like to hear your thoughts about my gimp skills: http://i.imagebanana.com/img/de0rirxr/PICT0007hdr.JPG playing around with hdr plugins and its just a pic of my bike,but i want to apply this on non-bike shots and was asking myself how it looks for others so far/plugin adjustment advice etc thanks edit:sorry for killing the loading time for this page,anyone can view it properly?

get that little boy a trials bike and his hyperactivity will turn out as a good thing! nice spot.

in theory it should make no difference,you´ve gone down 6 teeth on front and rear. but new drivetrain involves new bearings,maybe the old ones were knackered?

you make me feel totally unskilled because i cant hop up a tennis table to rear without brakes and so uncreative i can do it with brakes i should quit riding or go brakeless :wink2:

did you all notice how clerictgm starts stuff like that and everyone thinks its awful,but at the end of the day its always a good discussion lol weird

those pedals had a snack woah!

signature move was the x-up haha,awesome stuff
