In 2011 Sun Ringlé launched the ADD Pro wheelset which uses 30mm wide tubeless ready rims and 28 Wheelsmith double butted straight pull spokes laced to premium cartridge bearing hubs. The wheelset weighs in at an even 2000g and is available in a 20mm front hub and 135×12, 142×12, 150×12, 157×12 rear hub configurations.The ADD Pros are built up into a visually attractive package with polished laser etched hubs and subtle graphics on the rims.
For 2012 the ADD line expanded to include 2 more variations that use the same rim but are built using different hub and spoke combinations in order to create more economic choices.
MSRP: PRO - $750 USD, EXPERT - $600 USD, COMP – OEM only at this time. Click here

My first thought about the ADD Pros was that a 28 spoke downhill wheelset wouldn't hold up to the abuse that I dish out, which regularly includes poor line choices and cased landings. Despite those (my) challenges I've been genuinely impressed with them so far in fact I've found the ADD Pros to be as stiff and burly as any other wheelset I've used exhibiting now more lateral flex than a more conventional 32 spoke wheelset. The wheels were hammered down rocky downhill trails and they are as straight now as the day I pulled them out of the box.
The wheelset comes with all the adapters for the given width i.e. the 135mm width hubs come with 135 and 142 adapters and the 150mm width comes with 150 and 157mm adapters. The hubs are constructed with 3 pawls in a 24 tooth ratchet ring giving 15 degrees of rotation between contact points. Service can be done with regular tools.
The ADD Pro wheelset comes tubeless ready with Stan yellow tape, valves and sealant. I found mounting tires to be a tight fit, but I've been running tubeless setups for around 6 or 7 years now and they sealed up better than anything I've used so far. So much so that after mounting a set of Minions and intending add sealant later, I got busy doing something else and completely forgot. It wasn't until a week later while on an out of town riding trip that I remembered I hadn't put the sealant in. They hadn't lost a single psi. Not wanting to tempt fate, I put the sealant in when I arrived back home and they continue to be air tight
If you're looking for a light tubeless DH wheelset that won't break the bank, have a look at the ADD Pros.
