James_Porter Posted July 2, 2005 Report Share Posted July 2, 2005 jimbo uses v*z rims now (Y) but he did use 321's and his brake was ace. pad wasnt all on the rim but that didnt seem to matter as his brake was very good everytime i went on it.

ScotchDave Posted July 2, 2005 Report Share Posted July 2, 2005 Probably wore to the shape of the rim. Quote Link to comment Share on other sites More sharing options...
Davetrials Posted July 2, 2005 Report Share Posted July 2, 2005 dannys was ground weired and his pads slotted right on, id give it ago. I plan on doing it soon, cost mavic rims are beastos to grind. Quote Link to comment Share on other sites More sharing options...
dave33 Posted July 3, 2005 Author Report Share Posted July 3, 2005 (edited) the rim doesnt have a braking surface as its designed for a disc,i know danny smith done it but has any one on here got one on now? there is a lip of around 6-8 but with an angle grinder it would be easy to make a braking surface as iv done this on an old f219 disc rim and was great (Y) the rims are 680 grams which is lighter than a koxx isint it and thats before any drilling and im 100% that its stronger than any koxx rim,echo,onza........ i will be doing this soon when i get my rim altho i have one on the front of my santa cruz which im temped to go steal now, no better wait (Y)" edit typo :"> Edited July 3, 2005 by dave33 Quote Link to comment Share on other sites More sharing options...
Michael Hardman Posted July 3, 2005 Report Share Posted July 3, 2005 Jimbo has, he used it for ages and was an amazing brake Quote Link to comment Share on other sites More sharing options...
gazmaz03 Posted July 3, 2005 Report Share Posted July 3, 2005 No sorry I don`t no anybody that has used one. I use a D521 and they are perfect just spend that little more and get one worth the money. Get it in CD and then get some Heatsink Konigs. You will have the perfect brake. Gaz (Y) Quote Link to comment Share on other sites More sharing options...

Gaz (Y) ← Yes but there too narrow for use in most frames these days, hence using the 8mm wider 321.. EDIT: Hmm What about one of new Tioga rims?

Todge Posted July 3, 2005 Report Share Posted July 3, 2005 Just looked at my front d321 and it seems there is enough room to run magura pads on it, just. So im gonna build one up shortly, on a profile. Quote Link to comment Share on other sites More sharing options...

Mr Motivator Posted July 3, 2005 Report Share Posted July 3, 2005 Yeah can you put up a pic please. Hold a pad on the surface and take a pic side on, remember to se your macro mode. Sam Quote Link to comment Share on other sites More sharing options...
Todge Posted August 4, 2005 Report Share Posted August 4, 2005 Hello Everybody. I have built my d321 on the rear up and am using Magura pads on it and its working a treat :blink: There is just enough sidewall to sit the pad on, the width is about 1mm under a Ronnie, and its much lighter (and stronger). I have decided not to run a grind because I personally like how the CD surface works for mmy bake as its very dependable, but a grind would be easy enough. I will get pics up as soon as my camera returns from being repaired for all to see. Todge Quote Link to comment Share on other sites More sharing options...
RyanRs Posted August 4, 2005 Report Share Posted August 4, 2005 i had a 321CD disk rim on back once... its like the D521 but .... STRONGER!!! this rim is immense! i clobbered the corner edge of a 2ft brick wall once at about 25 - 30 mph with the back wheel, (hand slipped when i bunnyhopped) .... the 321cd went BANG!!!! and all it did was slightly bend the lip edge (where the tyre sits) inward about 3/4 cm ... but the dish of the wheel ect was still perfect! didnt affect the trueness of the wheel what so ever... ..i was running a nokian galla 3.0 tyre on it with an intense DH tube though... but i used to run 15 psi .... funny thing was, i didnt even get a punchure!! i also set it up with a magura once, when i snapped me disk.... and belive it or not, it works pritty dam good!! but you only get half the pad to touch the rim, aS there isnt enough surface.. they are a bit weighty though..
