Not sure if this is posted here before... But very interesting stuff and claim from this new carbon clincher

Mavic Cosmic carbone clincher

The connection between the carbon and aluminum surfaces is apparently chemical, not mechanical, meaning it will only get stronger with time. We’re not exactly sure how that works, not being chemical engineers, but will have to just trust Mavic on this one.

The result is a rim that sees only a marginal weight penalty, if any at all (Mavic claims that its wheels have lower inertia figures than Zipp’s 303 Firecrest Clincher, suggesting rims of similar weight), and are extremely unlikely to fail catastrophically as a result of excessive brake heat. A win-win situation, we think.

Stopping

The final, but no less important issue with carbon clinchers is the brake surface itself. These have come a long way in recent years, with the latest from companies like Zipp and Bontrager hitting impressively high marks for stopping power and modulation. Mavic’s solution to the heat problems do help braking in that the rim is less likely to massively overheat, but most brake situations get nowhere near that mark. So simple, everyday brake pad friction becomes the primary concern.

Mavic’s tactic has been to add a proprietary surface treatment to its brake tracks in order to get them a bit closer to the power found on an aluminum rim, much like Enve does. The treatment is part of the carbon or resin itself, apparently, so will last the life of the rim.

The specs

Weight: 1545 grams, no base tape needed, without skewers. 670 front, 875 rear
Rim width: 19mm outside width. Uses threaded nipple inserts like the Ksyrium
Hub: Same as CXR80, aerodynamically shaped
Spokes: 16 front, 20 rear
Comes with: Skewers, Yksion GripLink and PowerLink tires, same Swisstop yellow pads Mavic recommends for all its wheels
Price: $2750

Mavic claims
Rim weight: a bit lighter than Zipp 303 FC and Reynolds 46 clincher (note: 40C is shallower than both), according to Mavic
Aerodynamics: Slightly less aero than Zipp, better than Reynolds (according to Mavic)
Braking distance (unknown test parameters): 45 meters for Mavic, Reynolds and Zipp take 90 meters in wet conditions.

Eh the new mavic 40c, is it the first carbon clincher? Then what is the Mavic cosmic carbone slr? Not carbon clincher?

i think this is the one i saw in actual:

Skurvy

it states for 12 year old boy but it's much bigger than the other model, can you look at the description and tell me if it's suitable for adults?

During the early 90's when mobile phones were still a luxury to own. We always ride  with two 1 ringgit coins tucked underneath our tights. Pushing my bike for miles on a clipless shoe at a kampung road on a raining evening. FML. Thank god a friendly chap voluteered to fetch me to the pekan for patching at a motor shop.

any bike pros can tell from link if suitable for adults？

also how is the spec? good? worth the money?

abang.. your hand gesture is wrong mar

should do this instead

i've found a new love...

R5CA is now gone and the new RCA is in... lighter and equally as expensive... USD10k...and only 345 will be made...

Cervelo claims to find the great compromise in the new Rca

$10,000 Cervélo RCA frame that weighs 667g - first look and ride


new nickel coated carbon steerer fork...


new squoval shape and new resin material...

someone posted this in FB ...  hilarious 

could be an outdated but it's well worth a look at Cav reaction..what say you?

On the other hand, Rapha gave me a free 50USD voucher because they didn't have the softshell gillet that i ordered and again it was a very late delivery (they should do something about their logistic system, otherwise it will be the cause of their demise).

On my previous order they game me a free arm screen warmers and a winter collar neck on top of a 15% voucher for my next order (due to late delivery as well)

How could I put an order which clearly states that an item is available, and after a week of no shipping and upon my complaint they reply with the item is out of stock? Well they are pretty generous in the customer service complaints and department, but really they should buckle up on their shipping flows.

Just finish reading about this bike..it was overly expensive! Less drag then the tarmac sl4 and with the minimalist design (non bulky frame), it is definitely my dream bike...but I can only dream about it
