Description Lightweight and super strong, the stealth PBO is the ultimate racing or training wheel. PBO technology brings wheel weight to a minimum, and helps to reduce rider fatigue.
Summary: Spinergy PBO Stealth
Excellent wheels. I have approximately 1k miles on them and they are true. The ride is extremely smooth and they roll well. Above 30 mph they really start rolling. Great for downhill descents.
Strengths: Price...less than 1k for the set. Nice firm but comfortable ride. Stay true over rough roads.
Weaknesses: None

Summary: I wanted an aero, carbon wheelset that I could train and race with. I did a 150 Km ride with these wheels on the weekend, and I am impressed. They are fast, areo and strong. The spokes make the road seem smoother.
I found riding downhill faster, and the flats faster. With climbing I didnt notice any improvement, but I wasnt expecting any.
These wheels are durable enough to race and train with.
I am overall very impressed, for the price they are an excellent wheelset.
Strengths: Aero, fast, smooth.
Weaknesses: A bit heavy for climbs.

Summary: Run these for almost six months now and - despite some trepidation when purchasing them (no-one seemed to have reviewed them and full carbon clinchers seemed unproven / untried) - I can now confirm that I absolutely made the right choice.
Strengths: Fast and smooth. Added almost 2mph to my normal flat speed compared to the Kyrium ES wheelset they replaced (even the hubs seem to spin more freely than the Mavics in your hand) and very smooth over the road. Also remained totally true and shown no signs of damage despite drops into the odd road crater. Great price (wasn't sure about spending almost double on Zipps or Reynolds) and great looks (gone for white spokes to match my frame).
Weaknesses: Not as light as claimed (weighed mine at just over 1600g) but then that's still a pretty lightweight real world weight. Standard skewers are v.heavy and were quickly replaced with some USE titanium spin stix... Bit strange feeling how much spoke flex on the non-drive side rear wheel out of the box (but they've never needed truing / sorting).

Bike Setup: Orbea Opal, Zipp carbon stem & Bar, Dura Ace and FSA team pro cranks
Summary: Purchased these to upgrade my an older yet very dependable set of Cane Creek wheels. These wheels really shine above 20mph. They hold thier speed very well with a comfortable ride. No weight advantage over an all-arount set like the krysiums but no complaints at speed.
Felt guilty training with these so I run a set of beaters now in the winter in case I hit a pot-hole in my am ride with a light although they seem bullet-proof.
Removed stickers and added michelin Pro-Race tires-- wow the ride is phonemenal. I'm 205lbs and no flex.
Strengths: Speed holding, comfort, bling
Weaknesses: Not the lightest wheelset, decent hill climber, did a race with alot of downhill and a high crosswind--yikes, good luck doing a recovery ride
