I feel of late I’m the person posting random question in the hope the good people that frequent these hallows threads can fill the gaps in my knowledge
I’ve done tons of searching and see that some Triton frames out there were used with a Street/Road Schlumpf
I know the Triton Triple frame has non-flush fit bearing mounts - meaning that with 42mm you don’t get a full complete circle.
However I’m wonder if this also means that the way they were designed meant that could accommodate but 42mm and 40mm bearings.
I can’t quite work out if those running Road Schlumpf hubs in Triton frames were using a completely custom frame or if in general Tritons play nicely with both bearing sizes?
No you can’t mount 40mm bearings in a machined 42mm housing (well you shouldn’t at least). Doing this will result in having 2 contact points on your bearings rather than having the whole clamps. Since the ball bearings are already pretty small in a Schlumpf hub, that’ll most likely damage it pretty quick.
Therein lies the rub - you can’t safely shim a Schlumpf unlike say a fixed gear unicycle. I’ve been tinkering with this route for a few weeks now in a KH frame but it just doesn’t feel secure enough…
Yeah that was in fact something I investigated and (poor) Jakob knows all about my musings and seeking a quote for options here.
In truth it would be a lovely single use frame for just this wheel set. And I’m far more likely to put down some £££ for a Flansberrium 27.5” and have this be at the current 42mm bearings so it is versatile.
I’m lucky to have a nearly functional 36” NightRider frame that has the older 40mm bearings and was already cold set and modified to work with the Schlumpf hub - just the saddle remains.
The 42 mm bearings are better I think because ,a normal wheel have the 42 mm bearings. Some hubs are different, like the old Koox Hub I’m steel. The Hub is a light hub but the bearings have an different. I don’t know how I mounting the bearings on the Koox Hub.
40 mm bearings that’s the Freestyle bearings from QU-AX steel square.
Sadly as this was for a schlumpf with non removal bearings the set you mentioned wasn’t an option.
I toyed with trying shims in a KH frame but the torque reaction of the gear would be too risky and they’d slip
I’ve ended up converting the frame pictured above to be rideable so we’re all good as it has 40mm bearing mounts. But I posted this thread when I wondered if my Triton could would with the 40mm bearings.
The thread was recently resurrected but the matter is fully resolved
