T.McMillan Posted November 2, 2009 Report Share Posted November 2, 2009 (edited) Another bit of information needed from as many trials riders possible! What rims do you use or would like to use on the front and why?Include all sorts of rims including Mavic, DT Swiss as well as trials specific rims etc.All opinions considered.RegardsTom Edited November 2, 2009 by T.McMillan Quote Link to comment Share on other sites More sharing options...
Ben John-Hynes Posted November 2, 2009 Report Share Posted November 2, 2009 Trials specific. Right balance of strength, weight and unique looks. Quote Link to comment Share on other sites More sharing options...
Mowgli Posted November 2, 2009 Report Share Posted November 2, 2009 i have gone for trials specific, i am keen on the dob magnesium rim as it is light and i have had no problems with it when running a disc. Quote Link to comment Share on other sites More sharing options...
notknown Posted November 2, 2009 Report Share Posted November 2, 2009 i wide mavic xc rm would be cool, but i dont think they do one wide enough, i know they do wider rims but then i dont think there is any weight advantage over a trials rim.

Jonny Jones Posted November 2, 2009 Report Share Posted November 2, 2009 I have run Mavic EX721's front and rear. Currently EX721 front and 'old-skool' D521 rear at the moment. In my past experience with Trials-specific rims (Try-all mainly) they just are not up to the job at all, and yet they call themselves Trials-specific components... friends of mine have killed Echo rims too in an incredibly short amount of time, they're not hard riders either! My Mavic's have served me for years without having to true them much at all... once every couple of months or something! So if Hope want to make a rim, its gotta be super strong, fairly light, have a PROPER joint (welded, not pinned or alike) and look the part which, lets face it, all Hope parts do!

Shaun H Posted November 2, 2009 Report Share Posted November 2, 2009 (edited) A wide, single wall rim with a Mavic equivalent material and joint weld would be my choice.So I guess a mix of MTB/trials specific...EDIT: Or they can machine the ultimate rim out of a massive slab of billet for me?

psycholist Posted November 3, 2009 Report Share Posted November 3, 2009 (edited) The width is the critical thing for a trials rim. Once the tyre doesn't roll off the side of the rim even at low pressure with trials levels of loading then you're sorted. Adding a slightly bigger diameter just inside the rim walls to hold usually relatively slack XC tyre beads in place while keeping the centre of the rim a small diameter to keep tyre removal easy you're set. Choosing a slightly harder grade of aluminium to improve its ability to hold grinds or possibly texturing the rim walls from the factory would be nice, though trying to get people to agree on one level of grind would be a bit of a chore...

bikeperson45 Posted November 3, 2009 Report Share Posted November 3, 2009 I have a Mavic D521 and really like it, pretty light and it doesn't buckle easily. The downside is the width, it I was running a rim brake it could suck, but good for me I'm not Quote Link to comment Share on other sites More sharing options...
Matthew62 Posted November 3, 2009 Report Share Posted November 3, 2009 Most trials rims are shit. I mean honestly, un-eyletted rims.....f**k 50grams, you can save that elswhere no problems. Rims must be eyeletted, if more trials rims were they'd last longer. I've run many d521's/ex721's over the years on many bikes and they've always been perfect and require hardly any maintenance.When i rode stock i used try-all rims. They were great in terms of width, but everywhere else there shit. its only in retrospect that i can say that and when i used them they didn't break, buckle that much or have any real problems, but honestly for the price of them they're awful. Not that light, not strong in the slightest and require so much frequent maintenance.Now im on 24'' im back to normal rims with eyelets (dv24) and its back to good old dependable wheels that dont need truing and tightening after every ride and its back to the good old days.Hope............please make trials rims they will be f**king immense. Everything else you've mae for trials has been of huge success, but on one condition, please make them in 24'' - i think that might even be a bigger market for you.

Luke Rainbird Posted November 3, 2009 Report Share Posted November 3, 2009 Eyelets aren't a huge issue, really. I've been running uneyeletted rims for years with no noticable difference compared to a rim with eyelets. The main issue with many trials rims is that are made from a slightly too soft or too brittle material, leading to either denting/flatting (due to basheritis) or cracking (due to basheritis) Quote Link to comment Share on other sites More sharing options...
ogre Posted November 3, 2009 Report Share Posted November 3, 2009 shouldnt you be going specific tf will blatently want trials rims, if you wana research dh rims etc, go on DH-forums? you should be looking at preference of single and double wall, width, disc specific or rim specific? how come trials rims are always "square" not triangular like some mtb/dh rims are we missing out on something with that or is it just a fashion/image thing?

I hate the way its advertised as a clever weight saving measure - its a cop out. You could shed that material weight through clever design, leaving out eyeletts is just cheap.They do add a significant differance just becuase you can tension wheels that much more meaning less truing/maintenance and reducing the risk of other trials rim related injuries. I think its even more important on 24'' rims where theres more chance of dodgy sideways landings from squiffy spin moves. As much as i like trialtech i thought it was awful that there 24'' rims are un-eyeletted, there just is no point - why pay for a weaker in comparison wheel when you could have eyeletts?

N.Wood Posted November 4, 2009 Report Share Posted November 4, 2009 Eyelets have made bugger all difference for me in the 8 years I've been riding. I'll have a cheaper, lighter rim thanks. Quote Link to comment Share on other sites More sharing options...
forteh Posted November 4, 2009 Report Share Posted November 4, 2009 In general trials rim quality is dire, both in material and finishing. A decent width rim with mavic material and finish quality would be awesome, reckon a well executed hop rim would be very popular indeed Quote Link to comment Share on other sites More sharing options...
Matthew62 Posted November 4, 2009 Report Share Posted November 4, 2009 (edited) Completely agree. Everyone is looking at this from only a trials specific point of view. The lack of quality in trials specific rims would not be accepted in any other discipline. The shit quality is passed off because its 'light' or 'weight saving' when in reality a good mavic rim weights less anyway. Also as trials has little lateral movement on impact so rims dont need to resists sideways wobble all that much so again may seem to be strong and last well but all they're put through is direct impacts.Again people saying eyeletts don't make a differance - thats just stupid. Its not even cheaper not having them - trials rims are frickin expensive for what they are. I've had experience with many different rims and it is just fact that rims without eyeletts need to be trued regularly and should be checked constantly as they are always loosing tension. This really is not a good thing for the sake of a small amount of weight. Why does no other discipline have un-eyeletted rims?I'm sure hope would do a great job of making rims but as i mentioned before for the tgs style stock riders they'll stick to a 7 inch single wall cheese wheel whereas 24'' guys will want something more normal that can handle riding fast, spinnign moves, rough impacts whilst still being light. Trials always seems to behind other areas of mtb'ing. Its good that we have trials specific parts these days, but its a shame a lot of them are shit and don't rival the strnegth/weight/cost ratio of more traditional parts.My bike now has only trials specifc frame and forks, all other parts are more general mtb stuff (hope, dmr, deity, fsa etc) and its the best running bike i've ever had and doesn't need checking and sorting out as much as my previous koxx/full trials specific bike did. Some trials specific stuff is brilliant, i'm not saying dont make it but i think Hope could make some phenomenal wheels that would put whats out there to shame.

I run uneyeletted rims. I don't need to check tension constantly as they don't lose tension. I've never had any issues with any rim on that front to be fair, and that's with some bloody student building my wheels for the past few years...

craigjames Posted November 4, 2009 Report Share Posted November 4, 2009 I dont think eyelets or the lack of are the issue i think its more to do with the material and the quality of such used in trials products.Saying trials rims aren't subjected to sideways loadings when riding is absolute tosh, watch any video and tell me where the forces put through the rim are applied exactly in line with the rim itself.I think if a material similar used to the rims made by mavic and to an extent alex were used and the quality of production were increased then things would get sorted, but with the numbers involved with purchasing trials specific rims i can't imagine that will ever happen, economies of scale exploited by the big names just can't be applied here.

Matt Burrows Posted November 4, 2009 Report Share Posted November 4, 2009 I think you guys have gone away from the point slightly! Hope are NOT going to be making rims! Trials isn't exactly their priority and they are far too busy making MTB components to think about making CNC rims for such a small market. They have a big machine for building wheels which they use to build all their 'Hope Hoops' wheelsets. Judging by how quick the machine can build wheels they probably have spare machine time, and thought it might be a good idea to sell full trials wheels. This is just research to see what rims would sell best. Quote Link to comment Share on other sites More sharing options...

This is so they can sell complete wheels cheaper than what people buy separate rims and hubs and get shop's to build them for etc.HOPE HOOPS!
