Seem to be some very good reviews on
CRC web page, apart from those who are whining about the weight.
The important thing to note is that 1455 is the model name & the weight is stated as 1640g.
DT Swiss are a world renowned wheel manufacturer & quality should be right up there.
At £240 (currently) they seem like a steal at the price, they were being sold at £199 by CRC back in January.
With an original RRP of £900 they are still worth it, this is training wheel money.
For comparison, Mavic Aksium are quoted at 1730g & retail around £230.
