No I got excited an just put them on.they are very solid feeling. I paid the extra $ for the dh version( more carbon layers). Im running tubeless an have had no issues.
Altho they are are 700c road wheels - I have a pair of 'diy-bike' carbon clincher rims that split down the middle of the rim/tube bed after 2 months, and approx 1500kms. Never at max rated pressure, 75kg rider.
diy indicated they would warranty the wheels - but only if I send the rims back. Interesting that shipping out of China is subsidized by the Chinese govt - which may give the impression shipping is 'relatively cheap'. Not so. Shipping bike wheels from Canada to China will end up costing ~$200 for surface (by boat with delivery time measured in months) or almost $400 by air. diy warranty specifies Postal Service - or the goods will be blocked by Chinese customs. diy also indicates shipping cost of the replacement wheels must be paid by the customer.
It seems even tho there is a warranty policy - the actual cost of warranty in my case is excessive. Cost of original wheels ~$412(ebay), Original Shipping cost ~$122 Cost of return warranty shipping in CDN$ (air ~$555) (surface ~$322)
for a dubious replacement product. I suggest if you opt for Chinese carbon - at least avoid diy-bike.
