    I recently bought Chinese import carbon clinchers. The front wheel broke on me so I sent it back to the manufacturer. They are sending me a replacement but are telling me that all the U shaped are out of stock and they have V shape left and is it ok to send on one of those? I don't have a clue what the difference is... Are they pulling a fast one on me... Any advice would be appreciated! Wait for a U shape or take the V?

    u shape supposedly bit more aerodynamic at the same time there is no wind tunnel data avaialble of chinese wheels so you never know anyways....
    v shape tends to be fastest with narrow tyres 19-21mm
    u shape tends to be fastest with 23-25 mm tyres which is a good thing for irish roads .

    You mind me asking how it broke? Is it a crack or a rim failure? I was considering buying some chinese wheels from an e-bay dealer but dont like the sound of wheels breaking. Would you mind providing the supplier, PM if you do not want to put on the forum

    Agree with Peters comments on U vs V
    Cheers

    Had Carbon rims and they actually melted on a long downhill wet section due to heat from friction with brake pads... Used the cork board brake pads provided... They were ultra light 60mm carbon clinchers I bought from Arron bikes on eBay

    Thsts the supplier I was looking at. They say that those rims can withstand high temps, thats not good but atleast it wasn't a rim failure. Thanks for the info
