PaRtZ Posted June 6, 2006 Report Share Posted June 6, 2006 http://www.ridinghighuk.com/8_piston.htmI mean even for DH 6pots are powerful enough? Quote Link to comment Share on other sites More sharing options...
ScotchDave Posted June 6, 2006 Report Share Posted June 6, 2006 There is no such thing as powerful enough, for example vee brakes were "powerful enough", but now everyone uses discs... Quote Link to comment Share on other sites More sharing options...

ramps Posted June 6, 2006 Report Share Posted June 6, 2006 wow. I obviously what one, who could resist an 8 pot brake? And I don't even care how heavy it is. Quote Link to comment Share on other sites More sharing options...
Hobnobs Posted June 6, 2006 Report Share Posted June 6, 2006 Ti plated rotor too, they are rather nice. Too bad i will never think about using them. Quote Link to comment Share on other sites More sharing options...

adamtrials Posted June 6, 2006 Report Share Posted June 6, 2006 Is it just me or does the 6 pot look like the clarks clim8 one? Quote Link to comment Share on other sites More sharing options...
PaRtZ Posted June 6, 2006 Author Report Share Posted June 6, 2006 Also how is that illustrated picture, and I quote "Bled and ready to ride?"I'd like to see someone try using that..... Quote Link to comment Share on other sites More sharing options...
STEVE-0 Posted June 6, 2006 Report Share Posted June 6, 2006 Overkill is one way of putting it! The size of that lever is riDICulous! You could probably snap your bars by putting that beast at one end of them... Mint colour thoughSteve Quote Link to comment Share on other sites More sharing options...
Rob Thomson Posted June 6, 2006 Report Share Posted June 6, 2006 Course. But who doesnt accept free stuff.Uhh, Gandi?Nah i really couldn't justify buying one...my 203 twin pot hayes with its 3 year old pads is enoguh for me Utterly pointless IMO...

Danny Posted June 6, 2006 Report Share Posted June 6, 2006 Can anyone remember the proper maths behind hydraulics?Surely if there's more pistons then the pressure applied to the lever is spread out amongst them meaning less pressure per pad?More/larger pads equals more friction but less pressure as its more spread out so overall less force?Or have i got the wrong end of the stick?

You are indeed holding the incorrect end of the stick. I can't remember how/can't be bothered to explain it properly but more pots should equal more power, and also more modulation as mentioned in the description thingy.One thing that does worry me is there's no mention of weight.... I wouldn't mind a set to check out on my Coiler though hehe Quote Link to comment Share on other sites More sharing options...
Inspired Dave Posted June 6, 2006 Report Share Posted June 6, 2006 The advantages of more pistons are something along the lines of:Slimmer (and therefore stiffer) caliper while still retaining the same overall slave piston area.Lots of surface area to get rid of heat.Can be used to give better modulation (different sized pistons to let the brakes feed in).Probably more but I can't be bothered to think right now But, they're heavy and expensive. As for the pressure per pad thing - discs dont really rely on pressure. Two very flat surfaces will try and stick themselves together (Seisimir Effect? I can't remember exactly), so if you have two very large flat surfaces (big pad and large rotor contact), it'll work well. If you want more pressure too, you can just put bigger holes in the rotor.The brake looks alright, would rather something less generic-looking on my bike though!Adam (on Dave's PC cos mine is dead ) Quote Link to comment Share on other sites More sharing options...
philking Posted June 6, 2006 Report Share Posted June 6, 2006 Well Danny, Thats us told! On topic - i think it is ugly and un-necessary Quote Link to comment Share on other sites More sharing options...
Robwalker Posted June 6, 2006 Report Share Posted June 6, 2006 (edited) Nice piece of kit there, but i would say it more for the likes of downhill/freeride? There's jus too much more than needed there for it to suit trials, however the 4pot does look very tempting and at a pretty decent price too! Maybe ill get one RobEDIT: My point exactly Edited June 6, 2006 by Robwalker Quote Link to comment Share on other sites More sharing options...

Ben Geary Posted June 6, 2006 Report Share Posted June 6, 2006 Looks a beasty bit of kit, bet it weighs quite a bit though. Quote Link to comment Share on other sites More sharing options...
T.McMillan Posted June 6, 2006 Report Share Posted June 6, 2006 That is what i call RAD, very nice and crazy i want one who cares about weight and price i bet it stops u nicely, launching you over handlebars Quote Link to comment Share on other sites More sharing options...
