coda competition hub on alexrims r390

Bikerbaboon

I have a stock trek 1.7 2009 and i am thinking of replacing the wheels with coda competition hub on alexrims r390 as the rear is coming in about 400g less. Does any one have any input on whats a better set of wheels ?
The wheels are used but the look OK the front hub will needs a service as its a bit gritty.

So good idead to get them serviced and put them on or should i stick with the stock wheels?

Bike will be used for training rides.


thanks for any help
