Strengths:    great rolling wheelset- good looks, stiffness, and durability.

Weaknesses:    As the reviews indicate, rear spoke broke after about 2,000 miles- HOWEVER, the set came with a nice spoke tool. I'm an absolute amature when it comes to wheel maintenance, but I bought a spoke for $10 simply replaced it, tightened it like the other spokes and it was completely fixed....very little effort with a great result. And when the spoke broke, I didn't notice it until after the ride.

Bottom Line:   
AAA+++

Strengths:    Looks, stiff ride, hold speed well

Weaknesses:    durability

Bottom Line:   
I bought a set of S40 wheels May 2011. I'm a <140lb female rider...non-racer but can hang with a group at 24 to 25mph. Smooth roads and no hills where I ride. In Dec 2011, had a rear spoke break completely off the wheel in mid-ride. I was able to ride home and LBS contacted SRAM who immediately replaced the set. After MINIMAL riding over the winter (mostly rode tri bike) on May 10, 2012I was looking at wheels before an evening ride and noticed a CRACK in the NEW rear wheel in between 2 spokes and not near the valve stem hole. Aluminum surface and all other surfaces are fine and no impact hits!!! Unbelievable!!! I learned that these wheels are discontinued- and for good reason!!!

Strengths:    The decals are reflective
They coast and hold speed like a rocket
Climb well
Make a cool carbon woooshing noise


Weaknesses:    None

Bottom Line:   
I have used these from every thing from training rides to CAT 4/5 racing. They are great wheels and I have never had any problems w/ cracked time or breaking spokes like the others. Iv hit huge pot holes and even crashed in a road race with these and not even knocked them out of true. I think the problem some people forget is to go back and check/ tighten the spokes after the first couple of rides if you do that they will all have a chance to be tightened properly and you won't have any problems and things popping.

Strengths:    Price, Looks, Comfortable Ride, Performance

Weaknesses:    Hope there isn't a durability or workmanship issue! At least Sram stood by their product!!

Bottom Line:   
Just finished the RAAM using my S40/S60's. Loved the performance and the ride!, but on the last day, I noticed the carbon on the front S40 cracking. The front wheel was still true. The rear S60 was great. I don't remember hitting any potholes, etc. Don's Bikes called Sram, and they are sending me a new one--no problems!!

Sram S40 hubs

I have a set of S40's that I want to know are the hubs any good? I want to use the hubs in a wheel set but don't know a lot about them. Are they worth saving from these wheels or should I just junk them? ThanksRead More »
