General Disc Radness (formerly disc wheel valuation thread)

Will do later yea. It's a few inches long, feels like it was a pothole kinda impact so the outer sheet is cracked along and delaminated, but structurally it feels alright.

Stupidly heavy though

Where it needs the outer edge? Sketchyyyyyyyy

Yea indeed. I paid £160 for front and rear as a set, from Poland, so I considered the front a freebie anyway. Shame though.

Got this beauty today for £2.50 locally, so I can test the rear later:

Where can I physically pick up one of these today in London?

Aaaaand the rear now shows the same thing.

Think I got sold a duff pair.

EDIT: the front which has the worse crack, pulled it open a bit, looks like it's superficial but incredibly annoying. By the looks of construction the outer panel is aesthetic more than functional. Not sure I wanna pull the whole layer off and find out for sure.

Are there spokes inside??

sounds a bit like my Ambrosio disc, Ive already spent a small fortune having it professionally fixed by fiberglass specialists only to chip the edge again and fork out more money. If its like mine its a bit like how an old surfboard is made, a foam core laminated with glass matting. They just dont stand up to British roads running 19-20mm tubs. Another issue is that people fill dents/sand and repaint them damaging the gel coat.

@young_gun not sure it's spokes, the wheel's very thin and flat see pic pre-freewheel installation. I think it's something else heavy, like a girder.

@schnelly I nearly bought the fibre repair kit from the auto repair shop today, might try contact adhesive first, then resin if no joy. Did you ever see inside yours?

Really wondering if it has weights in it like that mavic one, glued into cavities, pushing on the disc it feels hollow at regular intervals.

Second pic, I pulled the cover as much as possible without too much damage, it's just glued onto the disc, which appears to be composite with circular cavities filled with foam.

mines an ambrosio by logos type disc, theres certainly no panel i can lift like that, when a small amount of material broke off at the rims edge i could see foam underneath, the outer material is probably the depth shown in your photo though, about 1mm. Its deffo not good that you can lift a big section like that, its one hell of a crack. Your hub looks different to mine so maybe a different wheel altogether, mine uses 6 little bolts to connect the two sides of the hub and when its removed i can again see the inner construction of the wheel. It wouldnt surprise me if it was a Polski wheel by Expert as they seemed to copy a lot of the existing wheels at the time using glass fiber.

I can't tell from the pics what's going on there, but it looks like the skin has debonded from the core.

If that's what has happened, Use a two part adhesive to stick it back down, something like Araldite or Double Bubble. Don't need anything mega strong but don't use solvent based. Use a lolly stick to poke some adhesive down between the skin and wipe off any excess.

Will do. May try the contact adhesive I have from shoe repair before I try a two part or fibre, it is stupidly strong and a little flexible.

They were sold to me as Russian/Polish so may have originally looked like fake Ambrosio, can't be sure with all the paint. Attempts to remove it are stripping decals underneath too. Might try clean where the hub is fixed to the wheel to compare with others'.

Gipiemme rear disc wheel, Ebay £175, it's made of........wood!!!!!!! Is it April fools day!!!! Has anyone ever seen one before, I'm tempted!??!

Weights about 5kg :D

Yeah, they are a thing. Apparently a genuine thing back in the day.

There seem to be quite a few NOS regularly on eBay, same seller, so I don't know if they're originals or what. The plywood face looks quite fresh for what would be a ~25 year old wheel.

They started making the type you found within the last 5 or 10 years, as a sort of 'capitalisation of fixie culture' thing. They could be reissues of something the company made decades ago, but most probably are only a few years old.

Article from 2014 - new wooden wheels mentioned in final few paragraphs.

actually what i rate about that wooden wheel is that it uses the same hub the old ambrosio by logos discs were fitted with-seeing as theyre very hard to find i thought about buying one just to swipe the hub to make my fiberglass version like new. i dont have a better pic but its here on this bike, it was in a right state when i got it but after an overhaul and a coat of black..

Hi, I'm new here, thanks for advance for any advice. I'm currently restoring this lo pro which came with a Mavic Challenger rear wheel.

Does anyone have any experience of servicing these? It runs smooth but I know it's been in a shed since 1991! It looks like has circlips holding the retaining nuts in place?

The cassette is a 7 speed suntour screw on type.

I can't find anything despite trawling the internet.

I am after a front disc wheel but they seem to be quite rare and fairly expensive (it will only be used a few times each year).

I have two spare road discs, a Ghibli (cassette version ) and a HED freewheel (screw on). Any thoughts on using either as a front?

I think the Ghibli is the least likely to be able to be converted. I think if I can get the right sized axle in the HED then that may work.

Anyone done anything similar?

(Guesswork..)

Looks like this?

I think the hed disc would be like a specialized tri spoke with freewheel threading:

Get a new m10 front axle from shimano (velosolo sells spares: bottom of page -> http://velosolo.co.uk/shopmisc.html)
and get/make correct new spacers for 100mm spacing

or look at the end of this thread:

or in this thread (from this post and on)

Done it with a Hed. Mine took the same axel as the specialized trispokes. Hed is sold out of track axels but still has qr setups nos

Some pop up in russia, mainly fluidisk etc. I think the hed would be the best bet aslong as its equally lenticular on both sides like so (). Not like > (}

I bought a 26" converted screw on rear and it works perfect respaced properly after some trial and error. Some are not symmetrical, the shimano hub versions from what I remember

Bugger, just been into the garage to check and it is non-symmetrical.

I think the cassette Ghibli is probably not possible to convert to a front.

Shimano 700c Hed currently set as a front

Thanks for all of the replies. What model is that @young_gun Is the campag version symmetrical?
