install a 112 carbon wheel to 120 O.L.D frame possible?
Hi fellows,
I'm very interested to install a set of 16" tri-spoke carbon wheels for a better look and lighter weight.
My bike is a v-brake single speed with front 74mm and rear 120 O.L.D. so the 74mm front wheel is easy to find.
However, the closest spec wheels available in the market all come with 112 O.L.D.and 3 speed hub.
Questions:
1-Is it possible to install this 112 O.L.D. to my 120 O.L.D. with a simple modification or adapting device?
2-What is the lightest solution to install a single-speed gear to a 3 speed hub?
PS: I cannot attach photos due to newbie status

I’m assuming you have a bike similar to a Brompton, which is why the 112mm/74mm 16” wheels are what you can find.
You can probably add a 4mm spacer on each side of the hub before the locknut. There might be a chainline issue if the crank is set out further than a 112mm OLD.
Not familiar enough, but maybe someone will chime in.

Can Hubsmith HUB CINCH HS-HCR01R do the job as spacers in such a case?
If there is a chainline alignment issue, can the rear sprocket be adjusted by adding thin spacers along the 3 speed cassette free hub?

You need to post a picture of your hub. Some hubs have a big hollow axle in the middle and screwed on endcaps. Some hubs have one long skinny threaded axle. The former might let you put a 4mm spacer on there. The latter would require you to scrounge up an 8mm longer axle.

If you haven't bought the wheel yet and you don't know exactly how the hub looks , I would advice you not to do it. You don't want to buy it and then find out it doesn't work.

Thanks for your advice. I found a good seller who is willing to custom make a 120 O.L.D.for me finally after providing them the spec requirement details..
