I'm wanting input on thread on disc adapter. I have a wheelset using White Industries hubs that I haven't used in several years. These came on our Bushnell these are Deep V rims and we switched to a set with Dyads as that bike is set-up more for touring and gravel. Our other bike is a Speedster which is more of a sport bike for us which has disc set-up. I've seen a threaded ring available which can be fitted with a disc which I think can be used on this wheel. Am I correct on that, and if so are there any issues with doing that. I'm guessing all disc set-up used this before disc specific hubs were designed. Love your thoughts as these wheels are just sitting in the basement and only have about 1000 miles. All I'd need to do is purchase a disc front hub and have the rim re-laced with new spokes.

Is that threading designed to install a drag brake? I have non-drive side threading on my hub, which is how one installs the drum for the Arai drum brake (which were common on tandems into the 1990s). Is the bike otherwise set up to run disc brakes? For other reasons, I posted a thread about my hub today that includes photos.

Lots of folks used thread-on adapters for installing disc rotors on drum brake hubs. It's important that you get the right thickness adapter for your hub and frame. IIRC, there are 3 or 4 different standards. Call one of the major tandem dealers for best results. It's also important to grease the threads if you ever want to remove the adapter.

Thank you OneIsAllYouNeed. I had called White Industries last year and was told you couldn't use this hub for disc but then saw the threaded rings on one of the Tandem specific shop's website. It would be awesome to have a set of Deep V wheels for our Speedster for the cost of a hub and spokes. :-)

Random Tandem, the bike I would be fitting these to is a tandem set-up for disc wheels. They are from our tandem that uses "V" brake and drag brake which we've gone to wider wheels for more touring and gravel. I wouldn't put disc wheels on a non-disc set-up without some assurances that the frame and fork would handle the it. I've seen folks who have reinforced the non-drive rear triangle and added disc mounts with a rattle-can touch-up paint job. What is your bike?

I did not mean to imply that you would not know your equipment, I guess I was just demonstrating my ignorance. It was suggested in the Bike Mechanics thread that I should look for the disk adapters, but I do not have any tandems that are modern enough to run disk brakes. My two steel tandems are a 23" - 23" c.1987 Kuwahara Adventurer with 27" wheels (that I have toured on with my older child - now 18) and a 21" - 18" c.1995 Miyata Duplicross with 26" wheels (that I ride with my son, who is 12). The Kuwahara is my tandem of choice, but it requires a tall stoker. I also have a Yakota 16" - 14" Twin Peaks that I rode when my son was 8, but it is one tandem too many (and for me, too short).

Hey, no worries, I wasn't taking it wrong. Actually I was more concerned that if you do retro-fit a bike for disc brakes you consider what might need to be reinforces on that frame. I hope all goes well for you, I love that you are riding with your 12 year old. We had an old Gitane we rode when our kids were small.
