Looking at the disc version of this rim for my new wheelset. I weigh about 190-195 ride mostly XC with an occasional 4-5 footer thrown in there. The bike is a Coiler with 6x6 travel. My question is how wide of a tire can I run without issues. I swap back and forth between Panaracer Fire XC 2.1's, Panaracer Fire FR 2.4's, and Weirwolf 2.5's. My main concern is the 2.4's which are huge. Will these rims work for me or should I look for something wider? These rims are about 100 grams lighter than anything I have found.

Not the rim for a rider of your weight doing 5' drops. The 717 Disc is an XC race rim. You can use the wider tires on it though they are not as stable for drops as on a wider rim.

I am using Alex FD28 rims (28mm/21mm inside), 500g, on my Coiler DL for trail riding. The Mavic XM719 (460g) would work, too.

How are those Alex rims holding up for you? Are they staying true pretty well?
No issues. I do use the stock wheels for the lift area DH days.

717's for XC and All Mountain

I have used these rims for years mated to King hubs. Each set has been built by a friend that has great wheel building skills.This year I have a 2005 Spec. Stumpy Expert 120. I weigh 160lbs and ride hard, hitting every drop or jump I can. I have never had a problem with the wheels staying true, bending or flat spotting. I do keep the spoke tension equal and check the wheels often. I'm the type of rider that actually enjoys the maintenance aspect of bikes, so I'm pretty consistent with checking and repairing my rides. I have used a 2.5 WTB Weirwolf on the front (last year), with no issues. I presently have a 2.35 Kenda Blue Groove Stick-E on the front with no problems. All tires are sized a little different, I don't think you will have any problems regardless of what you choose. The extra volume you will get with the larger tires will also help keep you from damaging the wheels. Just make sure the wheels are properly built in the first place.

Thinking of going the Universal Cycles route. I was looking at the Alex FD 28, Mavic 717, or the 719 shig mentioned with Hope Bulb 20mm front and Hope XC rear. Anyone had any experience with Universal Cycles custom wheel building?

Good choice!

Wound up going with a set of DT Swiss EX 5.1d's, Hope Bulb 20mm front, Hope XC rear, and DT Swiss Revolution spokes. The Alex FD 28's weren't in stock.
Good choice, you won't be sorry!
DT Swiss/Eclipse have a tubeless conversion kit available for these rims, apparently rather expensive but works well.

Hmmm, I'd seriously re-think that spoke choice if I were you. Others may disagree, but I'd very highly recommend against Revo's for that build. Supercomps are the lightest DT spoke I would even consider to be appropriate for what you described. On disc wheels, I typically would only use Revo's for very light riders and/or XC racing (and I would consider them marginal even for that).

Didn't really think about spoke durability as being an issue. DT's site is sort of vague in their description of spoke usage. I just saw an opportunity to save a lot of weight here and went with it. I really don't have a rep for breaking things and my stock sun singletracks only came out of true once this season. Maybe these will be okay with a good bit of tension? Have you had bad experences with these spokes?

My experience with very light gauge spokes and disc wheels was durability is not a huge issue but lateral flex was a big problem. I started having tire rub on the rear that was not there before. Could feel the extra movement in hard corners, too. This was with thicker spokes than the Revos.

The SuperComps Larry mentioned are less than 40g per wheelset heavier than the Revos.

The other choice would be Sapim CX-Ray or DT aerolite spokes that are the same weight as the Revos but their forged blade shape lets them build into a very solid wheel - at twice the cost. I use CX-Rays in several wheelsets

Thanks for pointing this out. I called Universal and luckily they had not started the build process. I changed to the Competition spokes just to be sure. This is the first wheelset I have purchased and I'm still learning the ropes on certain mechanical aspects of bikes. I suffer badly from the "wanting it all syndrome." Something light, yet durable, yet cheap. A bike I can huck big stuff, yet ride XC all day on. The Coiler wound up being the compromise
:). Anyway thanks for your intelligent insight to the people who chimed in on this. I respect your opinion Shiggy, because you've likely been there and done that or just plain know better. :)

You will not really notice the "extra" 100g on your Coiler. Saved a few bucks, too!
