Are you fitting that Roubaix with a BB30? Have you had a BB30 before? If not, I suggest you tell the LBS to smear bearing fit compound on the BB axle so as to prevent the thing from creaking as it flexes microscopically within the inner races. The compound needs to go on the axle at the drive side and inside the bearing inner race at the non-drive side so as to stand the best chance of not being wiped off as they insert the axle.
It's getting one of these fitted:

I'm hoping fitting one of these instead of a standard BB30 avoids all the dreaded creaks
I'll be fitting the chainset myself when it comes back to me and will make sure its lubed up first, thanks for the heads up
In other news my band on to braze on adapter arrived today so I've just finished fitting it. A very quick and instantly sweaty ride around the block suggests this is going to be a beast of a commuter now
It seems to have maintained its easy going and rugged traits, gained a bit of speed and agility and lost a bit of weight, result!
Before:
After:
Really pleased with the result
First real test should be Monday morning on my next commute
I'll be interested to see what effect it has on my average speed and journey time, probably marginal at best
