Muel Posted January 29, 2008 Report Share Posted January 29, 2008 Yes, you can get disc profiles. Ask Tarty.Also, you could modify a Pro 2, it has been done I believe. Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted January 29, 2008 Report Share Posted January 29, 2008 http://www.trials-forum.co.uk/forum/index....howtopic=112884Don't think they come in red though.Both the Profile and a King are incorrect spacing and require some 'tweaking' to get it to work...

JT! Posted January 29, 2008 Author Report Share Posted January 29, 2008 So is that profile pictured 116mm? Quote Link to comment Share on other sites More sharing options...
NVWOCI WVS Posted January 29, 2008 Report Share Posted January 29, 2008 So is that profile pictured 116mm?yep, thats the bmx racing mutation...i think its the hub body of a 135mm on a 116mm axel so the disc doesnt align properly...anyone fancy one of these?

NVWOCI WVS Posted January 29, 2008 Report Share Posted January 29, 2008 no joy on the profile website but they only make disc shells for their mtb 135mm hubs...so i'm resuming it is right, and i've heard that before...you hsve to machine the discmount on the hub down by like 4.75mm i think Quote Link to comment Share on other sites More sharing options...
Sponge Posted January 29, 2008 Report Share Posted January 29, 2008 Yep, you can get Profiles in red. Whatever colour anodized you see products in, you can always get it special ordered in the colour you want. Not too sure on that spacing issue though...

JT! Posted January 29, 2008 Author Report Share Posted January 29, 2008 KK.Think an email to profile will clear that up. Quote Link to comment Share on other sites More sharing options...
JT! Posted January 31, 2008 Author Report Share Posted January 31, 2008 First of all, BMX spacing is 110mm.(I think i referd to the hubs as 116mm by mistake)Our older hubs used 114mm spacing, because many frames weren't truly 110mm, but our Mini Hubs, both 3/8 and 14mm, are now 110mm. The high flange hubs with the stud axles are still 114mm. The BMX disc hub uses the same hubshell as our 8-9 speed mountain bike hub, but with BMX axles and spacing. If you choose the solid 14mm axle, or the Mini Hub style 3/8 allen bolts, then there is 10.3mm between the disc mount and the dropout. If you choose the stud-type axles, there is 12mm between the disc mount and the dropout. If you need more room, you could put a couple of washers between the cone and the drop-out. We've probably sold less than 10 of this style of hub, so it's not something we've invested a lot of research and design into- it's just a tiny tiny niche market. I don't even know what frame's have disc brake mounts. I'm guessing that most of the people who are looking at disc brakes on a 20 inch are trials riders, and it seems to me that the Magura rim brake hydraulics are probably a better option, but then again, I know next to nothing about trials other than the three or four YouTube videos I've seen of insane English dudes who can bunnyhop 5 feet onto a post. If the design will work for your application, great, but there simply isn't enough demand for them to warrant a new design or a unique hubshell.So does that mean it will or wont work?

AdamR28 Posted January 31, 2008 Report Share Posted January 31, 2008 So does that mean it will or wont work?Both the Profile and a King are incorrect spacing and require some 'tweaking' to get it to work...As the guy's said, the setup will give you 10.2mm space between the disc mount on the hub and disc mount on the frame. IS is 15mm. A snail cam would take up 3mm of this room (and another 3mm the other side) but you're then up to 116mm axle length and you still need to find another 2mm. I've seen all sorts of horrible solutions in the past (grinding calipers, bad setups), but the best in my opinion is facing a little off the disc mount combined with turning ~1.5mm off the hub shell. As you can see from the pic above, theres plenty of meat on the disc mount to allow you to do this.Ads Quote Link to comment Share on other sites More sharing options...

I'll put my efforts into bugging profile to make one instead. The hub's there they just need to stick a disc mount on it. Seing as though there's no alternative surely it would sell!

AdamR28 Posted January 31, 2008 Report Share Posted January 31, 2008 No probs Unfortunately I don't think it would be feasible... We talked with Profile a while back about making some 32h hubs (an even smaller change than the disc mount) and they didn't think it was worth doing Quote Link to comment Share on other sites More sharing options...
NVWOCI WVS Posted January 31, 2008 Report Share Posted January 31, 2008 would you be interested in a hope xc hub modified to fit a mod?... Quote Link to comment Share on other sites More sharing options...

I've got a +40 adaptor on my disc mount, and then my caliper is spaced so its about 1.5-2mm back over. In theory if I filed down my snail cams a bit more I could eliminate about 1mm of spacers, and it would be a bit neater, but it's all good.So yeah, CK hub, 2 3mm spacers inside the dropouts, and spacers on the disc mount and you should be fine. Snail cams on the outside allow you to adjust your chain normally. Quote Link to comment Share on other sites More sharing options...

JT! Posted February 5, 2008 Author Report Share Posted February 5, 2008 "The thing is, trials is a tiny market. How many people out there are actually riding trials? It takes sales of at least 150-200 items to even make back the money invested in designing a new hub- are there even that many people riding trials seriously enough to drop 200 plus dollars on a rear hub, that don't already have a Hope or a King? If there are, forgive me, I'm asking out of ignorance."150 Profile disc sales?Yey or ney? Quote Link to comment Share on other sites More sharing options...
*Tom* Posted February 5, 2008 Report Share Posted February 5, 2008 If i ran a back disk i'd buy one, the profile on my bike at the moment is mint *touch wood*I would of thought they'd sell 150 - 200 think about all the riders worldwide, im pretty sure a fair few people would buy them Quote Link to comment Share on other sites More sharing options...
