a Cross Country Rider
Date Reviewed: July 14, 2009
Weaknesses: My rear wheel cracked all around the middle on the inside. I noticed that the brakes were jolting for about 2 weeks. I stopped when I got a puncture and I was very worried when I saw what I'd been riding. I only rode on these for 6 months at 50-60 psi and mostly on the road. I don't jump, and not an agressive rider. I'm going for DT Swiss replacements.

Strengths: Light. Stay true.
Weaknesses: They break in half.
I'm only 160 pounds, and I only do XC. Anything more than an 18" drop is an accident. But I've now broken 4 of these rims, in exactly the same way. (2+2, bought about a year apart, from different stores) They crack right under the rim strip, and start to separate. When you start to feel a bumpiness in the breaks, pull off the tire and take a look. You'll see a crack right down the middle, under the strip. If you run disks, you might not even notice until they literally break in half.
I liked them while they worked. They're light, fairly cheap, and they somehow stay true, even after they crack. But I can't give a higher rating because they're dangerous.

Strengths: stay true for a long time, very light, look cool, inexpensive
Weaknesses: not very strong
these rims are awsome and very light, i definately recommend them for the cross country rider. i had to get a new one because i ruined mine in a race when i flatted and didn't want to fix it, so i just kept ridding. that was okay though because they don't cost a fortune!!

Strengths: Light, durable, stay true
Weaknesses: a bit narrow but that's what you get when buying some of the lightest rims on the market
I have no clue how anyone can say that these rims are weak. I'm a 220 lb rider and have ridden these rims over everything (log piles, rock gardens, through streams, etc) and raced with them and so far for over a year I'm yet to need to true these rims. I'd recommend that anyone looking to buy new rims to stop looking any further.

Weaknesses: my sticker is starting to come off
well lets just say the combination of these rims, 14/15 spokes, and wtb hubs, all in black of course, these rims rule. lightwieght, perty, and i dont remember how much they cost so that must be a good thing. Here's the story:.... Mid-Atlantic Super Series race 10: so i need to place good in this race to take the series. everythings going good until i flat in the front. no prob..i have stans notubes. i whip out my pump, fill her up and im off again. final lap:about 2 or so miles left, the second flat comes, this time the tire comes off the rim. i wont be able to put it back on so i start to run. i get passed and move into third. forget this this i thought, im ridin! i wrap my tire around my handlebars and ride. these rims are good, but they dont track through the rock gardens like my wildgrippers. how good are they?? let's just say that to this day i haven't touched them with anything but some sandpaper to remove some burrs. ohh yeah, in another race some dude crashed into me and bent my rear rim but all was well as it trued right up. buy these rims if you want to be cool

IT's a great Rim, I bought them from the Demo specials at Jensons Laced to LX Hubs, There Sweet Rims for the trail and held up to quite a lot but I should never have Done that free-ride. So I retired those Awesome wheels to my XC Bike and bought Some F519 Laced to Disc XT For my Free-riding,. IF your looking for some tough XC rims, these fit into that catagory with extreme smoothness.
Just wish to enquire whether the above mentioned rims can be fitted with the eclipse tubeless system.

Are the Sun UFO rims any good? they seem to weigh as much as the 517 and cost pretty much the same. Say i have a good deal on the UFOs... take it or go with the non-deal 517? (717, from some reason are yet to get to Israel).
Anyone has an experience with the UFOs?
Thanks.Read More »
