zoster Posted January 3, 2009 Report Share Posted January 3, 2009 Hi!I am buiding a new custom frame at marino, and i must decide what distance between the v-mounts i want, therefore i must decide how wide i want my rim on the back.What would be the advanteges of a narrower rim? (a 38mm one)If it's about tire roll, i don't think tire roll is really an issue if you keep the tube on a wide rim at a fairly high pressure (how i like it).thanks Quote Link to comment Share on other sites More sharing options...
CurtisRider Posted January 3, 2009 Report Share Posted January 3, 2009 looks like you answered it yourself really, go for 38mm, its gonna save a few grams too Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted January 3, 2009 Report Share Posted January 3, 2009 A 38mm rim is far from narrow and is plenty wide enoughI'm running DX32 on the back of my Inspired and have had no issues whatsoever. I certainly wouldn't want anything wider Quote Link to comment Share on other sites More sharing options...
aener Posted January 3, 2009 Report Share Posted January 3, 2009 I've got a 38 I seem to get the feeling that super-wide rims are better for "proper trials", and being that 24" is usually more streety - no worries. Quote Link to comment Share on other sites More sharing options...
zoster Posted January 3, 2009 Author Report Share Posted January 3, 2009 looks like you answered it yourself really, go for 38mm, its gonna save a few grams too i can't see how i answered my own question..i was saying that a wider rim doesn't really mean more tire draganyway, if you all say 38 is ok, then i guess is ok, but i stii don't know why it is better then a 47 one...

craigjames Posted January 3, 2009 Report Share Posted January 3, 2009 narrower rim and a narrower tire, easier for spins as a smaller contact patch with the ground. i use dx32's on my 26" with a v and its more than wide enough, running a 2.4" tyre at 18psi and dont tend to get much tyre roll if any, so with higer pressures you'll have none. if you dont need the extra grip that bigger volume tyres on a wide rim at low pressures gives you then go for the 38mm rim.

Cookyboy Posted January 3, 2009 Report Share Posted January 3, 2009 38, anythin more is a bit much on a 24 i recs Quote Link to comment Share on other sites More sharing options...
Fish-Finger-er Posted January 3, 2009 Report Share Posted January 3, 2009 Go for a 38mm, anything more is just excessively wide imo. We all used to ride on d521, which were sub 30mm(27-28ish) if i remember correctly, back then we never moaned they where too narrow. I'm running a dx32 right now, dont really have an issue with its width. Think going wider than about 40mm is stupid. Stick with 38mm, and if for some reason you feel the need to get a 43mm rim, you can always shave a couple of mm off pads to get the extra width if they wont fit(or better still buy second hand pads) you go for 43mm, and decide youd like a narrower rim to save weight and make streety moves a bit easier, your a bit knackered Quote Link to comment Share on other sites More sharing options...
Mat Smith! Posted January 3, 2009 Report Share Posted January 3, 2009 The wider the frame the wider bb you will need because you will end up hitting your feet on rear vee, i think :\.wider bb = more likely to snap.Mat Quote Link to comment Share on other sites More sharing options...
zoster Posted January 3, 2009 Author Report Share Posted January 3, 2009 theanks for all the answers!now what would you suggest for the front? 38 as well or narrower (i'd think a 32 or 34 would be proper but might be hard to find) Quote Link to comment Share on other sites More sharing options...

zoster Posted January 3, 2009 Author Report Share Posted January 3, 2009 if you looked 4 posts up i did check that out before i posted, and indeed it would be great for the front, but i didn't seem to find it for sale (i'm from romania so there are restrictions.., but i didn't look much for it yet) Quote Link to comment Share on other sites More sharing options...

Fish-Finger-er Posted January 4, 2009 Report Share Posted January 4, 2009 Wrong thread, or can't read? Nah for once I think Matts spot on the point, and something none of us had though about, by putting the V mounts further apart on a 24, theyll be way more succeptible to catching your heel/the crank arm, if your catching the crank arm, youll have to have a wider bb to clear the V brake arms.

zoster Posted January 4, 2009 Author Report Share Posted January 4, 2009 ok, back to rims..for the record, here are some options for the front (31-36mm wide):http://www.chainreactioncycles.com/Models.aspx?ModelID=26277http://www.chainreactioncycles.com/Models.aspx?ModelID=26265http://www.chainreactioncycles.com/Models.aspx?ModelID=26270http://www.chainreactioncycles.com/Models.aspx?ModelID=26273http://www.chainreactioncycles.com/Models.aspx?ModelID=26274http://tartybikes.co.uk/product.php?produc...;category_id=43and for the back, the 24-bicycles have the Y.M.I.A.B. v-brake rim which is 42mm wide, which sounds good..

aener Posted January 4, 2009 Report Share Posted January 4, 2009 :$ My mistake.I forgot about the whole frame designing bit.Sorry Matt Quote Link to comment Share on other sites More sharing options...
spaceman Posted January 6, 2009 Report Share Posted January 6, 2009 Definitely 38. The trialtech ones would be excellent. And those Tioga DH rims on tarty are good too.But some riders are using Sun Rhynolite XLs? Those are 29.5mm.I'm using a 32, which I'm changing to a DX32 soon (that's a 39).

NVWOCI WVS Posted January 6, 2009 Report Share Posted January 6, 2009 Just ordered some alienation 440 rims for mine. I think theyre about 35mm wide, but I'm running dmr moto diggers and about 35 to 40psi Quote Link to comment Share on other sites More sharing options...
eskimo Posted January 6, 2009 Report Share Posted January 6, 2009 I would go with the DX32 on the rear, as you do run higher pressure and it's generally an all round rim. If the frame is suited to 38mm rim then your have no problem switching to a much skinnier Mavic if your using Vee rear.Ryno Lite welded would be a happy medium for the front i'd say. Or even the rear. But as long as your sure you don't need a massive rear rim for the rear then rims aren't a problem to change at a later date, no?
