I bought this bike around October last year. I have always appreciated Cervelo's and when this Soloist came up secondhand in my size (61cm) for a good price I jumped at it.
It had been owned by an occasional triathlete who had used it lightly and lost interest so when I purchased it, it had an X lab aero cage mount and an iSM saddle. I stripped that off and here's a photo of what it looked like with the original wheels, ITM finishing kit and ultegra 6600.
I ordered lots of parts in anticipation of the final build but in the interim I put some FSA omega bars and stem I had on (the ITM finishing kit was very heavy) and put my wheel set from my old bike on (Shimano RS81 C35's) and trimmed the cables down to the proper length. It then weighed 8.635kg and looked like this:
I used that as my baseline and ordered a Fizik Arione (K:ium rails), FSA SL-K stem and bars (120mm, 44cm respectively) and some SL-K composite cages (28g each) and some Look Keo 2 Max pedals which I put Ti spindles in. I hunted down a full Dura Ace 7800 group set on eBay and changed the stem, seatpost and bidon cage bolts for Ti, and put on some KCNC chainring bolts and Ti skewers.
I also changed to 25mm tyres (Veloflex Master) with Maxxis flyweight tubes. Here is how it looks now:
Final weight was 7980g with Garmin mount and cadence/speed sensors. I am quite pleased with this especially as it has a heavy fork (Wolf racing CL with cr-mo steerer, about 480g) and wheelset.
I am hoping to have some older (2009-2010) Zipp 808 tubulara on it by the end of the year and maybe a 3T Funda Pro for around 7.3kg and a whole lot of aero for such an older aluminium bike.
I wish I had the budget some others do to spend on my bikes!!
