Mercury Wheels has upped their own upper end with the new M-Zero carbon tubular wheels. For climbers that want the added power of disc brakes on the descents, the new M-Zero’s use Extralite’s disc brake hubs and Sapim CX-Ray spokes to bring the wheelset weight all the way down to 1,050g.

That means a rider weight limit of just 75kg (165lbs), so they’re only for the little guys. Roll on for closeups and specs, plus a look at their very affordable new alloy disc brake wheels…

The tubular rims are 30mm deep and 25mm wide.

Extralite’s hubs are an exercise in minimalism.

Front hub weight is just 69g, rear is 145g. Available with 11-speed SRAM/Shimano or Campagnolo freehub bodies. Wheelset is $2,999.

Mercury’s shallow 25mm deep alloy wheels get a new rim extrusion, and they showcased it on their new disc brake option. It’s their own rim, and it has a rounded shape, which increases the strength by about 20% compared to last year’s more v-shaped rims. It’s also slightly wider, coming in at 23.5mm wide (18.5mm internal) at the top of the brake track and bulging to a hair over 25mm at the widest.

There’s a brake track on it, so it’s used for standard and disc brake builds. Retail is just $649. Weight is 1520g. They’re laced with Sapim Race spokes.

Front hub is available with either QR or 15mm thru axle end caps.

Rear can be QR, 12×135 or 12×142. Order it the way you need it, then get alternate axle caps separately if you need to mix it up.

I thought I was finally skinny, but then I read the rider weight limit.

@caliente: There are clydesdales, and there are jockeys…

Why can’t bicycle component makers update their websites when they introduce new products? I understand small business, blah,blah, blah… but the Internet is the where you live and die for product introductions and people interested in buying go looking.

There are clydesdales and there are jockeys, but 165’s less than a Boonen or Phinney at their Grand Tour leanest.

what I think is funny, the lighter you are the less braking power you need – ie, don’t need disc brakes. its the big guys who need better brakes and heat management.

is there a different weight recommendation for cyclocross use?

I’d like to see the data showing that “lighter” riders don’t benefit from using disc brakes.

Interesting b/c extralite disc hubs have a 200lb weight limit according to:

http://www.starbike.com/en/extralite-cyberrear/?currency=USD&vat=hide&gclid=CjwKEAjwhqShBRDS95LciqqaonISJADj1rga1IlMa6Ny9Unvu1f59LzSJAO_K_fXdhhSik0EBfDHnxoC8eTw_wcB

Also, extralite’s disc hubs weight 69 g and 145 g for the front and rear respectively (see link above).

48 cx-ray spokes at 260 mm is 204 g TOTAL. 69 g + 145 g + 204 g = 418g, Which means those shallow tubular hoops weigh ~632g minus nipples (1050g – 418g ).

Super heavy IMO. Where’s the value added?
And does width matter with shallow carbon tubulars? if they’re glued, they’re glued- its not like tire shape changes as with clinchers.

Divided by two. Divide 632 by two.

biggest annoyance = internal nipples on all their carbon tubulars. clinchers? external. WTF. so stupid, i told them so at IB. he tried to tell me about aero benefits. i said, “are you sure? because zipp says no.” he says that HED would say yes, and zipp is full of it. i go to the HED booth, they say external nipples make zero difference vs internal. so, mercury makes no sense.

Mercury Wheels is what I call a “sticker company” because that’s all they make.

632g divided by 2 is 316g per Alibaba carbon rim. Not bad, but half of ENVY’s tubular rims weigh less than that (you have to get into their 65mm deep stuff before going over that weight) and I didn’t even bother looking up Easton or Reynolds. But if you want to save grams on your wheelset by using radially-spoked disc hubs, go ahead, I’m sure the Mercury reps will regale you with their benefits.

Didn’t quite finish the equation there, Billy.

But Mike, I’m with you. You could get 28h ENVE 25s and slap these same hubs in there, come in as light or lighter, with a much higher weight limit.

Want to know why Mercury uses internal nipples on that 30mm tubular rim? Because that’s how it comes when you buy it from Gigantex.

You sure do pay a lot for those Mercury stickers!
