Is the Edge 520 actually out in the WIld? All the online resources I see seem to indicate that it will be another month but I have heard people talking about it like it is here.

I might have to call the LBS I preordered it from.

yes.... I got mine on monday.

got a link to that sale? I'm into their shoes.

echappist 08-05-15 05:09 PM

it's unlisted, but call them at 813-261-5098 or email at info@alebikewear.com

also, what size do you wear? Glorycycles may have your size still available

42.5, but what I want is a pair of Pistas (with the sweet laces & cover), not a model Ale is listing on their site :/

they've been pretty spot-on of late. now that units are coming in, the estimates actually mean something.

sometimes a dealer can get you one a bit faster.

shovelhd 08-06-15 06:22 PM

Thanks. No rush. I am buying from a dealer (coach).

i know. i should have said some orders are getting bumped up...rumor has it. ;-)

the good news re: the wait is that a few kinks should be ironed out.

Well, it turns out I cracked my Riivo's. There is a giant crack along the back of the heel, big enough to fit a small blade in there.

Apparently this isn't covered under warranty - the warranty is only 90 days and my shoes are just over a year old. I'm a bit peeved because I don't think a pair of $900 custom shoes should not crack like that. The one piece of good news is that Riivo said they can repair them for about $40, not including shipping there and back.

In the meantime, I am struggling to find shoes to wear. I need to find something because I have a four day trip to ride in the mountains planned for this weekend.

I tried my old Specialized Pros yesterday. When I first put them on, I thought, "These feel great, why did I ever get rid of them?" But 45 minutes later, when my toes were going numb, I remembered why. Also, the cant in the sole of the Specialized, the Varus or whatever it is, really messed with my knee. It was not happy.

I am going to try my Shimano shoes again this week. They are wide enough at the end of the shoe, but not wide enough in the middle of my foot.

And I am exchanging messages with a guy selling a pair of Lakes. I'm not sure they would get here in time though.

echappist 08-10-15 02:19 PM

Well the shoes are a bit larger than expected. If anyone wears size 43.5, i'll let them go for $195 plus shipping

FFS, I'm sure the Fondo crowd won't mind


says Bontrager. “That time issue is a minor annoyance for most riders, but pro teams will have to work out a way to swap a wheel quickly in a race. It might mean bike swaps become more common.”

Most MTB World Cup wheel changes are faster than anything you'll watch in the ProTour.

To be honest, pro road teams are embarassingly slow.

They change out wheels mid-race? I thought they just swapped bikes these days. Pro roadies probably should if they go disc, too.

Yeah. You have to start and finish the race on the same frame. You can swap anything but the frame. I've never seen anything besides wheels, except when Jose Hermida had a pedal back out last year. Made it to the tech zone, mechanic wrenched one back in, and I think he still finished in the top 20. He was close to the pits, though.

In most other cases, he probably would have been a DNF.

Point being, there is nothing inherently "slower" with thru axles or disc brakes. Hell, I've seen teams with a Kabolt (TA with a 6mm hex hed) and impact wrench in the pits lately. NASCAR style.

LesterOfPuppets 08-10-15 04:40 PM

Aha. I kinda figured they swapped like in CX these days.

Makes sense that MTB quick changes are more crucial than in pro road races though. 80 minute race vs. 6 hour stage. And you don't get to hang onto or draft a buncha cars to get back to the pack.

News to me, funny the industry people don't make the argument

The Zipp guy sounds like an idiot. He makes it sound like his company is doing something that others are not.

“We want to provide the best options for our customers. Zipp continues to design wheels and hubs that allow the end user to easily change between quick-release and thru-axle. Our most recent disc brake hubs, for example, allow the rider to change between quick-release and thru-axle simply by swapping the end-caps by hand.”

Oh? And so can most every other brand out there. My DT 240s can run 5mm QR, 9mm QR, 15mm TA or 20mm TA on the front, and 5mm QR, 10mm QR, 142x12mm TA, and 135x12mm TA on the rear. So can Hope, Chris King, etc.

I can do the swap, on both wheels, in under 2 minutes.

that headed in the wrong (size) direction - saw your post on one of the other selling forums and got stoked till I read the fine print. :/

Racer Ex 08-10-15 06:33 PM

I'm a 43.5

You should just give them to me. Especially considering I didn't read back through the thread to find out what they were (besides shoes I would guess...although I guess it could be a sports bra).

Box them up, they arrive, and it would be like early Christmas.

revchuck 08-10-15 07:14 PM

Ex...don't tell me...you've got moobs?

I will have to defer to you here, not familiar with the MTB world. Still, would complicate neutral wheel support, no? I mean, I still see steel frames with DT shifters at lots of races, most will probably not be riding disk wheels but some will. I thought that part of the reason neutral wheel service worked was the ubiquity of 700c rim brake wheels.

Until 11s, neutral wheel support via Mavic or SRAM was the same way. 10s Shimano/SRAM and Campy (and 9s before that) were not very friendly with each other. Now, they're close enough that you can throw any wheel you want on, provided it's not a super wide range cassette.

New UCI rules forbidding circumvention of lawyer tabs (by filing or other means) contribute to make thru-axle wheel changes not much of a penalty in pro racing. Not having changed a thru-axle wheel myself, I don't know how it compares. But I think it's about time the QR went away in favor of more reliable and technically superior wheel-retention mechanisms.

revchuck 08-11-15 08:49 AM

IME there's nothing unreliable about QR skewers...as long as they're used/tightened correctly. I also note that I have no experience in cyclocross, which may be a deciding factor.

I'm not talking about wheel security per se. The QR skewer is a terrible design from a usability standpoint. The whole problem is that it is not obvious enough when they are being used or tightened incorrectly, which given the possible consequences of misuse, is a big deal. A whole conversation about it, here, if anyone is interested: WHBP #26 - I Come Not to Praise The Quick Release But to Bury It ? Standard Double.

The technical issues with the stiffness and security of the mechanism are a separate issue from the usability problem. A QR hub tends to shift or twist slightly in the dropouts under various riding forces, like climbing or sprinting out of the saddle, or cornering. That's not a safety issue and it's not a problem with rim brakes. But with the much tighter tolerances needed for disc calipers, that's enough to move the brake rotor into contact with the pads. Pretty annoying. There's also the added safety benefit of making wheel ejection nigh impossible, and in theory there might be some slight benefits to handling with the stiffer front end you get with a thru-axle.
