|   Make non disc hubs disc compatible for a handful of grams | Scott479

This may very well be old news here but check out this link http://www.firstprinciples.ca/
They have what looks to be a well-thought out design to adapt our old hubs to disc use. I read it through and was impressed but wonder what the bottom line $$ is? Grams are minimal- even to us who post here! |

Jan 27, 2003 7:41 AM | | Who on earth wants to tear down and rebuild two wheels with some hokey add on disc plates. This item has a pretty high cheese factor. I wouldn't feel confident that those rotor adapters could stay rock solid either. |

Jan 27, 2003 2:23 PM | | Well excusssse me..... Actually they claim an enviable record of reliable service in DH usage so they shoud be more than up to the task of our puny XC inputs of stress. Besides there are plenty of quality non disc wheelsets waiting for what appears (at least to my eyes) to be a simple, inexpensive, and solid adoption of disc compatibility. What's an afternoon and $100 to have your old $500 wheels on disc? Still if you haven't confidence in the adapters design you'd never be comfortable with 'em and there's a junkyards worth of bike stuff industry's sold us-look at UST, biopace, SmartShocks.... |
| Id like to know who those top downhillers are they mention. | JIT
Jan 27, 2003 3:13 PM | | It seems odd that a top pro would use a "fix it" or "save your old stuff" type of product.....
I dont think this product will ever take off for various reasons. Yeah, its clever, but will it sell? I wouldnt think so. |

Jan 27, 2003 8:10 PM | | Their site lists the team riders and events/placings during the '02 season. I did a little more searching and found a detailed install and ride review on NSMB http://www.nsmb.com/gear/first_principles_07_02.php
I can't see why it wouldn't work but it's also good to see efforts to keep components current w/o falling back on a simple use n toss mentality and for that alone I hope it succeeds. |
| Hello!..UST is alive and fine. Not everyone wants goop or some... | DIRT BOY
Jan 28, 2003 9:31 AM | | strecthed out condom in their tires...LOL :-)
UST is great technolgy and is moving alongg and getting better everyday. I want to know what took so long to bring tubeless technology to bikes!

| UST has serious limits..... | JIT
Jan 28, 2003 10:22 AM | | I mean when you get light UST tires you are really defeating the whole purpose. My reasoning is because if you slam that thing on the rim its gonna rip the tire, just like a pinch flat on a tube. Granted it would take a harder hit to pinch a tire, it could happen. So why not just use a tube.
At least with sealant you have a chance of sealing holes.....
Ideally UST tires with no sealant need to be thick (and that means heavy). In my opinion light USTs are defeating the whole purpose.
What Im trying to say is, UST tires should be heavy to reap the benefits, but this makes it a disadvantage over standard tubes or latex. Light UST tires are risky in my opinion with out latex. Now your back to Stans set up..... |
| how did you get on the subject of UST anyway? nm | JIT

| I think that was how AMP attached their rotors | Sunny
Jan 27, 2003 9:49 PM | | way back when they came out with their disc brakes. What is old is new again... |
| Yep | ®i© Wi©to®
Jan 27, 2003 11:27 PM | | AMP used a ring, basically a new hub flange, that you bolted through three spoke eyelets. After spoking the wheel the spoke tension kept it all in place. It works fine.
The drawback: you have you have a Shimano rear hub. A friend of mine had a Ringlé Superduperbubba, and ended up having to machine a whole new adapter himself.
With disc brake becoming the norm, and disc hubs being readily available, I really don't see the point. |
| Yep | Scott479
Jan 28, 2003 7:54 AM | | Only 3 spokes and they work fine? They have ten on their setup so it should be bulletproof. So if you really like your hubs.....I just might give it a go! |

The point I could see is if you already have a wheelset lying around, you could do the conversion and only have to rebuild one side of the wheel. Or if you want just want to experiment with a "project."
The problem is, at $70 -$90 a set, that is practically the cost of a new set of XT disc hubs. For only an additional $15-$20 (assuming standard DB spokes, cheaper if use straight gague), you rebuild a new hub, with all new spokes (instead of just one side) to your old rim. Now, you have spent probably ~$100 to rebuild the set on used rims, when you could get a new wheelset for not that much more. With a quick search I was able to find a set as low as $130 with XT hubs.
If you take a hub that you may have lying around (say a 3-4yr old LX hub), I guess it can give you a lower weight disc hub (older LX standard R hub w/skewer 426 gms + 49 gm adapter = 475gms VS. 494gms for XT disc hub w/skewer), but is 19gms worth cobbing something together? Now if you have something lighter, like XTR, it might be the weight savings might be more significant, but why ruin a good set of hubs? Why not just sell 'em (oh the wonders of eBay and mtbr's classifieds) and put the money towards a new set of wheels?
I thought this was a neat concept when it first came out, but as it stands, in my book it is too expensive to be worthwhile. If the price was only $40- $50 a set (the cost of one new XT disc hub), it might make more sense. |
