Anyone know about replacing / changing trispoke hubs?

I have a spare 650c Specialized Carbon trispoke and was wondering if it was possible to change the hub to a front.

They're the same as the Hed3's. (Did Hed take over from Specialized?)

Anyone got any experience of this?

I've seen a few rear carbon wheels on the bay and was wondering which (if any) can have the hubs changed.

Any help appreciated,

Thanks.

Same thoughts here, I have seen a white rear tri-spoke (650) looking for a home for a while and was also wondering what it would take to run it as a front ?

I saw that too! ;-)
I'm sure it only need a couple of spare bits right?
It's been getting cheaper and cheaper.

I'm sure there must be a source of info. I've had no joy finding out.
I've heard some hubs can be changed.

Keep seeing nice rears for gears...

I emailed HED UK (in Sheffield) a few weeks back to ask if a Rear HED 3 with shimano cassette could be converted to 100mm front, and i simply got an email saying "NO" in massive type! Nice.

I believe though, that rear track specific HED 3s can have a shorted axle put in (100mm) so it can be run on the front, but you'll still have the sprocket threading on the outer shell of the hub...

I guess a lot of people have been bugging hed about this!

If it's a screw on block you could be right about using a shorter axle.
As long as you don't mind looking at the threads...

isn't objects or dog's front hed a rear wheel??

Where are they when you need em?!

i'm pretty sure one of theirs was.

Most normal hubs the flange to flange width is less on a rar than a front hub. It is only the axle spacers holding the spacers out so there is room for a cog and the bodies are abit wider as well. The hub bodies on a pair of hubs I have in front of me are

front, 80 mm with 10 mm worth of cone nuts and lock nuts on each side.
rear, 92 mm

Now the cone nut on the front protrude 3.3 mm so if the front cone nut were swapped with the rear the rear wheel could be spaced t0 92 +3.3+3.3=98.6mm without any lock nuts on the cones. If you uses some blue locktite on the cone nuts could you get away without lock nuts on the cones? With regular checking quite possibly.

I run a rear hed3 on the front witrh no problems.. I used a smaller axle and spacers.. Its a screw on block hub.

The Specialized I have is for a cassette.
Makes it more difficult.
Just seen this:

Wondering if it's possible to replace it with a front...

If you can change them, then surely.....?

hahahaha! i HAVE to get one of these!

Not as good as the Arrospok posters though!
In fact, though it's a joke, the spok posters are making me want one!
Reverse marketing?...

I dont think you can do it with the specialized tri spoke. From what I've heard The hed track conversion kit isnt compatiable even if you want to use it as a rear. Is it a shimano cassette hub?

don't get trispoke man.
it's all about scraper bikes these days

yeah, mine (object's) is a rear re-spaced. You don't need to buy a new hub! :)

saw someone rocking some scrapper styles at CM last month

It's for a Shimano 9 Speed. I saw the track conversion doesn't have a lockring!
Also, it's a 650 so I wouldn't want to use it as a rear.

I guess if nothing can be done, I'll sell it for its intended triathlon use...

But the one I have is for a cassette :-(

I'm using a rear Tri Spoke on the Front,
its for a screw on rear hub
I really shouldn't mention that i just hacksawed the quick release axel and added spacers should I?

What ASM said, that was a specialised dupont with screw on block.
Remove that + shorter axle = front wheel.

Tey even used to be sold with both axles as a kit.

It's a cassette hub.

Tey ?
Sort it out. Anyone would think you're typing with one hand.

HED site says...
So they think you shouldn't be swapping them around.

oh todd, that's a shame! Is it tub or clincher, your rim? I'm surprised that they don't have replacable hubs. Tekk a hacksaw to it? *Shrug*...

Is the width of the cassette part more than 100 mil?

HED definitely modified the design so I'm not suprised.

Oh and Timmy, You're a cunt!

??? What sorry ehh?

Are you come for a drink tonight?

Timmy. not Tommy.
Got a dinner date tonight I'm afraid.

you can get different hub axle arrangments. to change a front to a rear. but as mentioned it will be just screw on, no lockring thread.

people change spinergy's to fixed using a surly fixer thingy, all the time. if you need a new axle give us a holla as we have a tech dude thats makes stuff for our lab and he's spun up a new axle for me b4 ;)

Yes it's a shame. But like I said, it's spare so if anyone's interested in trying to convert it, I'll sell it. It's for tubs. I bought a (reasonably priced) pair! ;-)

what happened to the front then?

I'll be keeping the front. Wondered if I could convert the rear too.
I've seen so many great composite rear wheels and had been thinking about how to switch hubs.

I'm sure someone will buy it...

can someone explain "screw on blocks" i was tempted to buy one of these on ebay to run fixed.. but didn't like to take the risk. is there a way of running one of these as fixed rear?

cheers,

L

the screw on block is a cassette that screws on.
it has a single thread you could put a freewheel on safely, but not ideal to fixed riding as there is no second reverse thread for a lockring.
