    New R3 build, Pressfit 4624 BB vs BBright adapters?

    Just ordered a new R3 2014/15 frame to build up w/ DA 9000.  Really excited to get it on the road.  Using my existing wheels, carbon bars, saddle at lower cost than stock R3. 

    Any opinions re/ Rotor Pressfit 4624 bottom bracket vs Enduro or Wheels adapters for running the DA cranks?  Which adapters are better?

    Thanks!

     I've found the Wheels Manufacturing adapters to be very good.  Have been using them for 3,000+ miles with DA hollowtech cranks without any problems.

    After GT1's ringing endorsement, I decided to pull the trigger on one of these guys.  It's a very nice BB.  Went into the R5 very smooth with no popping.  Runs super smooth.  Was really nice that they include the plastic installation spacers and a tube of retaining compound as well.  What is interesting about it is that it has a metal sleeve which floats in between the bearings and I presume it keeps you from over pre-loading the bearings as it sits on the backside of the inner races of the bearings keeping things perfectly aligned and running very, very smooth and free.  It's quite an ingenious solution to running radial bearings in a BB.  I haven't seen mention of this inner sleeve anywhere else so it was a bit of a surprise.  The one downside I could see to that metal sleeve would be if someone decided to run a PF30 version with a 24mm crank and some adapters it would probably fall out of place and rattle.  I don't think it would be a good option in that case if someone was swapping out cranks that were of different spindle diameters and using adapters to accomplish that.   I second that it works well.  Smoothest pressfit BB I've ever felt.

     The same (ugly graphics) Rotor 3D+ I've always had on the R5.  I didn't use any spacers other than the 11.5 cone.  I might add a couple on the drive side to adjust chain line though but for now it seems OK.

    for me THE reason to buy them was the fact that they offer the 'Direct Fit Shimano' version

    no adapters, no shims nor spacers, no drive side bearing walking out, just a perfect, clean installation

     Agree, it may very well be the perfect pressfit BB.  Cervelo should consider spec'ing them OEM and putting this creaking business to bed once and for all.  If I was a Cervelo + Campy nut, the direct fit Campy one would be on my radar big time.
