Attractive Seatpost Quick Release Replacement Solutions

[dirttorpedo]

I have a Ritchey Ultra with Tom's classic fastback seat stay design. The frame came sans seatpost quick release and the frame requires a relatively long quick release so none of the period correct ones I've picked up over the years fits. I managed to buy an aftermarket modern version, but it was crap - plasticy, weak and fugly. I'm currently running a bolt and nut, which does the job, but looks terrible too. Wondering if anyone else has had a similar situation and found a nice looking replacement solution. doesn't need to be quick release - it just needs to function and have a bit of that ooh ahhh factor.

You've got unthreaded holes in a brazed-on collar, either side of the slot? 6mm, 8mm?

i have a few kicking around. what length do you need? base of head to end of threads.
do you need the smaller or larger diameter?

I think it's the larger diameter. I will measure tonight and get back to you. Would be awesome to source something period correct - they just look right.

Post a photo too - different designs expected different clamps

Ok, here are some photos of the seat cluster. So from the tape it looks like I need at least 40mm clear on a QR with the nut and washers fastened. The too short DX QR in the first photo fits perfectly and is 5-6mm in diameter.

i have what you are after. i have a couple qr's in the 49 to 52mm length.

Not the exact problem you’ve got but I found I could make a seatpost QR from an old wheel skewer. I wanted to reuse the Suntour one but it was too thick for the frame. This is from the thread I posted it in -

I found a bent and mangled Maillard wheel skewer in the drawer of doom and set to work - it was the only one that looked close without me sacrificing something shiny and complete.

I wanted to retain the Suntour end as it’s branded as well as the lever so was crossing my fingers it would be similar when dismantled View attachment 678462

And it was!

I think I may have thought about adapting wheel skewers to seat skewers at some point as I already had the correct size die - I’ve seen it suggested that these threads should be rolled not cut but this is what I’ve got.

So I cut the new skewer to size and finished it in my Makita cordless lathe with a file - engineers look away now

Et voila

The finished article, found an end that looked appropriate

And I’ve ended up with enough bits to make the Maillard in to a thick seat skewer, reckon I’ll eBay it for PayPal tokens!

However, one door opened and another closed, I found now that I can clamp it, the new bike needs a 26.8mm seatpost not a 26.6mm! Thought this was going to be a quick swap.
