Converting LF Record hub into 135 OLD?
 

I'm trying to use parts I have laying around and have a perfectly good set of low flange Record hubs. I'm building up a early 90's Cannondale H400 hybrid frame into my budget gravel bike. Being it's a hybrid it uses a MTB rear hub. It's getting equipped with a mixture of 80's Campag stuff...Triomphe, Chorus, C-Record. Just stuff I have laying around.

Wheels I have to build up for it and like I said I have these perfectly good Record hubs I want to use to keep with the theme. So just pick up a wider axle with the correct threading and find a spacer and call it a day?

wheels mfct. makes axles for exactly this kind of thing, SJS cycles carries them (probably amongst others). Wheel Axles - QR & Nutted products from SJS Cycles

This is the one you need, always use an axle that is 9-10 mm wider than the OLD you want. Need to have 4-5 mm sticking at each outer lock nut.

If you want to make a Bomb proof rear hub, you can go Soilid Axle, just cut to fit, and use track nuts.

I think that's a bit wide for a freewheel hub, even for a solid axle. Freehubs were invented for a reason.

I'll check at work as we should have those. I'll stick with a hollow axle and maybe grab a spare or two just in case because it is a bit of a stretch for a freewheeled hub.

You will bend axles.

How many speeds are you running?

I have done this but don't recommend it especially for a gravel grinder.

I needed a cheap quick way to upgrade to 8spd for accompanying a customer to work, sort of like a Domestique arrangement. I put long axle in a CampI hub with a Sachs 8spd FW. It worked OK with his Ergo group but I did go through an axle or two over the years I had that setup.

Decent shipmano STX and RCS level hubs are cheap and you go either 7 or 8 spd.

I was planning on using a 6 spd freewheel.

With a 6 speed maybe....just maybe it'll work. Here's what you do:

Gear side: Remove spacers to get the freewheel as close to the drop out as possible.
Non gear side: Add spacers until your at 135mm.

Don't be surprised if the axle is longer on the non-gear side.

You beat me to it. This is a great opportunity to minimize dish, thereby making for a stronger wheel.

If the chainline gets too radical and makes more than just small-small cross rattle the chain, then perhaps one needs to increase the cog-to-right dropout spacing, but, subject only to this caveat, I like your recommendation.

I put a 'Wheels' Campag replacement axle in , and added a spacer on the left end , did some dish-spoke adjustment..

QBP stocks the parts, too ... they're in 130 wide frames now.

Ordered a 142 chromoly "Wheels" axle so it'll be here Thursday from Quality. Should be an interesting build but fun.
