Having been through this with my friend's electroclash stash, 'appreciative' in this case would be getting more than 20p per record.

I'd just keep them or donate them to a charity shop, where they'll be appreciated in a different sense.

Take heed, the great electroclash revival of 2021 is coming

Where can one source a tandem in France? Asking for a friend.

@Vince ?

Have a look on leboncoin.fr

Remove the "professional" ads and search by area.

For some reason, they are never cheap so don't expect picking one up for less than 200€

Example of ones in the area our Champagne house is:

And I found a very cheap LOOK tandem at 300€, that's a good deal:

Good stuff, thank you Vince. Friend lives in the Languedoc so you are at the opposite end of the country!

@mdcc_tester Would you able to help us out and redraw this in a track version by any chance? Could you recommend someone who could make them and do you know roughly how much it might cost?

Thanks

Maybe there is still stock here, if you need a thread-on adaptor (but not good for fixed gear unless welded/glued/bolted on)

Troc-vélo is the main specialised marketplace. Better chance to find a good one on there than LBC, but you may have to spend a bit more. Saying that there's a Follis for 200€ atm which doesn't seem outrageous to me.
It's also worth contacting busy bike rental businesses, at least the good ones, as they change their fleet often. Last time I rented a tandem I was told by the guy there that they sold their bikes every year but they had a waiting list for their Cannondales tandems that was several years long.

do you know roughly how much it might cost?

Far more than it's worth.

If you have a threaded 6-speed freewheel hub and just want to make it into a suicide hub with a decent chainline, much the best way to do it is to move some spacers from right to left and re-dish the wheel.

If you have a monobloc type wheel (Disc, Hed3, Corima 4-spoke etc.) then you already have the adapter, and nothing I can do will make it less of a suicide hub.

Will an 11 speed road shifter and mech work as 10 speed on a 10 speed cassette? Can’t think why it wouldn’t as gaps betweeen sprockets are same?

The gaps are not the same. 3.74 vs 3.95 mm steps.

A 4700 shifter (uniquely) will make an 11 speed mech work with a 10 speed cassette, because its shift steps are specifically designed for it.

Damn, thanks for that info but annoying news for my spending.

It's for a sugino 75 tyranno disc wheel. The disc hub is threaded, where you would either use a track or road screw on fitting and change the axle and spacing accordingly.

I have a carbon track Sug disc which uses the same type of hub. It's an original track wheel, with lockring threaded fitting, which must have been glued on as it's not coming off, even with considerable force, so not as suicidal as one might think. Since no one is interested in buying the road disc in current condition I'd rather keep it and convert it to track with the help of loctite and a grub screw.

The disc hub is threaded

With what thread? How is the adapter registered radially to ensure that the bearings are coaxial?

It's not a complicated part to mass produce if you have control over the hub manufacturing too, but if you don't have access to Sugino's original manufacturing drawings there's measuring and hand fitting to do because you don't know what the original dimensions and tolerances were. That starts adding pretty fast when it all has to be included in the price of a single example. There are three threads which nobody has gauges for if they're not already a bicycle manufacturer. You need to be really in love with the idea to contemplate going ahead with the project, and you need to deliver the wheel and the freewheel adapter to the machinist.

maybe my google-fu isn't at his best, but anyone knows any european distributor for Simworks by Nitto parts? Looking to buy a stem and seatpost, but afraid to be shot dead by customs and everythings (I'm based in France) so any European retailer would be ideal!

I think Parts & Labour on Lewisham way - give them a call.

Edit: sorry didn't read properly. They're not a parts distributor they won't post to France...

Worth having a browse if you haven’t already?

Not sure if it helps, but I've recently bought a couple of simworks bits from Circle & co Japan.
Checkout is in Japanese but not difficult to navigate.

i've been having a crack at making some small custom parts on a lathe. i can't promise a quick turnaround, but i can at least investigate this for you. do you wanna shoot me a pm?

What are the cheapest, safe, plain black headset spacers known to mankind?

Lovely. Would really appreciate you giving it a go at least. PM incoming tomorrow

@mdcc_tester stuff? Get a slam the stem and top cap for a perfect finish?

tester stuff?

He said "cheapest"
