ok so im doing the whole shop around for wheels thing still. im starting to narrow down my choices though. ive been giving a set of Williams wheels a serious thought the only thing i cant really decide is if i want the System 19s or the System 30s. the 19s weight 1440g and with a height of you guessed it 19mm. the 30s weight in at 1580g and have a 30mm height. so is the 30mm even offer enough areo benefit to go with them and gain 140g? not that 1580g is heavy or anything but i am trying to find something light to shave some weight off the bike and since i live in the mountains. i only weigh 120lb on a good day most of the time its 5lb less so weight isnt really a factor for me. i do like the looks of the 30s better but thats not why im getting new wheels. so any suggestions would be greatly appreciated. oh and lets keep this on system 19s vs 30s please (not that ive ruled out other wheels)

Just got the new Williams 38C carbon clinchers. 1460 grams and aero. Great hoops. I had the older ones that were over 1600 grams, these really do feel lighter. By the way, I rode the other ones for over a year and sold them for close to $700, so they hold their value pretty good too.

If I had it in m budget to spend that much trust me I would. Even though they are very reasonable my wife has made it very clear not to spend over $500

I've had a set of 19s for 18mo or so, and have ridden them through a whole range of conditions. They've been great, rarely needed truing and roll very well. I'm a fan of the hybrid ceramic hubs. I do know some folks who have had some durability issues with 19s but that's not been my experience - I'm 150 fwiw. If you want to get a little bit weenie for hill climbs go for the 19s. If that's less important to you then I'd have no hesitation in recommending the 30s.

I had a similar dilemma when building my recent wheelset (Kinlin XR-200 or XR-300). I figured it this way: The aero difference is only 8mm (11mm in our case), which is not much. The weight difference is 130g (140g in your case), which is not much. Since it didn't matter much either way, I decided to go with the XR-200 just because it would be fun to tell people I had a set of 1375g clinchers. I also figured if I were to go aero, I would go all out and at least 50mm deep. The clincher (pun intended) was that I'm so slow, aero doesn't help me much anyway. The only thing I tossed out is that deeper rims tend to be stronger.

There's your food for thought.

I have the System 30s, very strong wheel! Ive hit a lot of potholes, the ones that make you cringe, but they are still true at 1500 miles! I went for the 30s coz I needed a more robust wheelset for daily use, plus they look cooler!

This. I also got XR200's so I can say I have 1200g clinchers. I like saying it.

This is a tough decision! I'm sure I'll be happy with either one I get. I'm a strong climber anyways even with my heavy wheels I have now and the 30s will still save me quiet a bit of weight. But I am trying to shave weight off my bike so the 1440g 19s are tempting. I've also read that the 30s weight more than advertised but don't know if that's the case with the 19s

19's seem a little shallow for rough roads and fast, winding decents. I'd prefer a stiffer wheel for those conditions.

Same decision here...Went for the 30's for a more robust wheel...

Could not be happier! The wheels have never been trued and have been ridden over lots of crap roads...

If I was 120 and climbing, I'd go with the 19's no doubt.

I have been very happy with my Williams wheels.

Get the 19s.

I just made the decision to go with a low profile wheel as well for pretty much the same reasons. Right now, I have a set of Stan's No Tubes Alpha 340s being laced to a Chris King front hub and a Powertap Pro rear. 28 spokes front and rear. They'll be plenty stiff and even with the Powertap weigh in around 1550g (would be right around 1300g without the PT and lose a few spokes, they'll go as low as 1200g). I really considered going with a set of Reynolds Assaults, which weigh around the same sans the Powertap, but like UK, I'm just not that fast and doubt I could benefit much from the aero wheels. I know I'll benefit from a good set of climbing wheels.

I had the older Systems 30's. Never very impressed with them. Not very stiff under my massive guads. Granted they where the older 16 spoke front and 20 rear version so your experience may very. Also, I couldn't purchase replacement parts at my LBS. At 160 I guess I'm to fat for them

Fixed.

.... guess it shows just how much flex those wheels produced out of the saddle on climbs or sprints.

Yeah, well at the moment I'm having a rough time flexing my right knee far enough to put my pants on, let alone ride a bicycle. This sucks.

17 posts to make this thread about you...yeah, you are off your game

You work from home but still wear pants? Well there goes one advantage of having your own business. I'll keep in the corporate machine if I have to wear pants either way.

I have 19s and 30s. I used the 19s for racing, the 30s for training and I weigh 178, both great wheels with zero issues. This next year I'll be racing on the 38 tubulars.

See that's what I was thinking. I'll be using these wheels for training as well as racing. Mostly crits but also some road races in my area so by default there is quite a bit of climbing. I will be ordering them at the end of the week so I have a little time to decide.

Nice to be able to choose between 19s and 30s! I'm right at 190 today. I fluctuate a lot and can be 200 or 185 on any given day depending upon how the weekend went or how much I've been able to work out.

I'm sold on the Williams Wheels as well. Love the looks. Love the positive reviews. Love the durability. For me, however, the choice is between the 30 and the 30X. 190 pounds is their listed limit for the 30, but I'm sure they build a little fudge factor in there. Also, my realllllly crappy stock Shimano RS10 wheels ($75 per pair for new ones!) have only gone out of true once in 5500 hard miles. Lots of hard hits and potholes not to mention that I was around 215 when I started riding on them.

Leaning towards the 30.

OK, what are the specs for this set and how much do you weigh? You've got to have something like 20 front/24 rear Aerolite spokes all around, laced to Tune hubs.

If it's for crits, I'd go with the deeper rim. Stiffness is an advantage, and weight is not a big deal (especially such a small difference). My set is mostly for climbing... and I'm now at my prescribed weight limit for them

their customer service is outstanding, get the 30's if you are racing crits.
