LiamWood! Posted April 16, 2007 Report Share Posted April 16, 2007 Well i think that the wider the rim is the wider the tyre can be so that must mean more grip. If you think about it imagine a thin rim with a tyre its going to be quite thin but with a wider rim the tyre can be spread out more so there will be more surface area therefore more grip, well thats my view on it anyway hope this helped Liam Quote Link to comment Share on other sites More sharing options...
NileBrown™ Posted April 16, 2007 Report Share Posted April 16, 2007 Hi , the differednce between wider and narrower rims are that when you put the tyre on the rim , the wider the rim , the tyre will be wider which will give a wider 'footprint' and therefore more grip. However wider rims tend to be heavy , especially undrilled wide rims. So unless your a weight nut and want a feather light bike , the narrow mavic will be fine but obviously won't give as much of a footprint. The alex rim will make the back end a bit heavyer as well so you would have to bear that in mind as well.cheers ,Nile Quote Link to comment Share on other sites More sharing options...
_Owen. Posted April 16, 2007 Report Share Posted April 16, 2007 you will get more ballance with a wider rim as there is more surface to ballance on. when i moved to a wider rear rim i noticed quite a big difference compared to cr*ppy narrow rims Quote Link to comment Share on other sites More sharing options...

1337 Trials Posted April 16, 2007 Report Share Posted April 16, 2007 I guess wider is better balance and the wider the rim the better looking, hehe. ~Matty Quote Link to comment Share on other sites More sharing options...
SomeoneNew Posted April 17, 2007 Report Share Posted April 17, 2007 The narrow rims (well 521's or whatever they are now) are stronger than the wider rims, but don't have as good tyre profile so can be prone to your tyre folding over when you run low psiI don't know whether they make balancing any easier, as I didn't notice any difference when i moved on to a ronnie from a 521, but I suppose ronnies arent super wide like some of the others Quote Link to comment Share on other sites More sharing options...
spmcfadden Posted April 17, 2007 Report Share Posted April 17, 2007 I haven't used the wider rims so don't know how strong they are, but Mavic have been making rims for years and years longer than the new companies so I'd say they probably know what they're doing better.The 729 is stronger and wider than the 521/721 but its disc only, not as wide as the trials specific ones but its lighter.

ogre Posted April 17, 2007 Report Share Posted April 17, 2007 with a wider rim you can run a lower pressure with less chance of the inertube getting a pinch-flat. Quote Link to comment Share on other sites More sharing options...
Ghetto Rider Posted April 17, 2007 Report Share Posted April 17, 2007 Wider rim's easier to balance on as they have a bigger "footprint" Dan Quote Link to comment Share on other sites More sharing options...
simtradan Posted April 20, 2007 Report Share Posted April 20, 2007 Not only will the wider rim give you more balance, but it will also give more bounce when gapping or hopping, as well as this, landings should be much softer due to the increased surface area acting on the rim.
