Since they're finally on my bike, I figured I'd write my first installment of my thoughts on my new (to me) wheelset, the Spinergy Stealth PBO that I bought from LowCel.

Appearance. Up close, the carbon weave is not perfectly even. Of course, it's way easier to get brushed aluminum to look perfect. But hey, the paint and clearcoat on the R3 leave that much to be desired, too, so I'm not going to complain about the slightly rough look of the wheels. The wheels look gorgeous on Vivian. While the silver Elan Aero has a showy look on Vivian, the Spinergy, with its deep carbon rim and its really thick spokes, has a menacing all business look. I think they'll look even better once I desticker them, which I plan to do as soon as I'm absolutely sure I intend to keep these wheels. (If for some reason I don't like them, I'd sell them.) It's amazing how different the bike looks with the wheelset swap.

Also, I'm not a big fan of Spinergy's QR skewers, so I'm running my Spinergy with the Rolf Prima titanium skewers. Besides, those Rolf Prima skewers are lighter. I use that set of skewers on all my wheelsets.

Mounting tubes/tires. Since my new tires haven't come in yet, I borrowed the tires on the Elan Aero. Probably a good thing anyway, since it allows for an apples to apples comparison. Mounting the tires on the Spinergy was really easy compared to on my other wheelsets. That was a pleasant surprise. Specialized long valve tubes are barely too short (as I had expected), being long enough that my Road Morph can pump them up, but my floor pump can't. I found that out when I accidentally stuck a long valve tube instead of an extra long valve tube into the wheel. The extra long valve tube is plenty long. The bad thing, though, is that the lighter, more compliant Specialized Turbo tubes aren't available in that extra long valve length, so I'm running the Specialized standard road tube.

Pre-ride impressions. These wheels are heavy. Of course, my reference point is the rediculously light Elan Aero, which makes most anything seem heavy. They feel about right for their claimed weight. The full carbon clincher that Spinergy now sells is 2 mm deeper and about 200 g lighter, but I'm not about to pay an arm and a leg for a wheelset that probably won't be my primary wheelset thanks to my gravitating toward hilly rides.

The rim is narrower than the Elan Aero rim, so a big adjustment in the brake setting is needed. No big deal. The wheelset is a bit out of true, as LowCel had told me it would be (and as he told me they came from the factory). Not much, mind you. Perhaps 1-2 mm. I guess I'm spoiled by the absurd level of true of the Elan Aeros. (My QA sheet claims the front wheel shipped 0.2 mm out of true. The rear, 0.1 mm. I can't actually verify that, but it's believable.)

The hub also doesn't seem as freely rotating as on the Elan Aero. On the Elan Aero, set the front wheel at any position, lift the bike, and the wheel will rotate on its own until the heaviest portion (directly opposite the valve stem) is facing down. On the Spinergy, set the front wheel at any position, lift the bike, and the wheel doesn't move at all. Likewise, the rear wheel on the Spinergy doesn't really move, but on the Elan Aero, as long as it's in the direction where it can freewheel, it will rotate on its own.

Yet to be determined. I have little doubt this wheelset will be more aero (with a 41 mm rim) than the Elan Aero (24 mm rim). I assume the wheelset will be stiffer, being heavier and deeper than the Elan Aero. My measure of this will be whether the brakes rub when set really close (as I'd like them to be). On the Elan Aero, I had to open up the brakes a bit past where I'd like them since otherwise, the front would rub a bit in corners and the rear would rub a bit when pedaling hard.

This wheelset is supposed to be really comfortable. dog hair tells me it makes his Blue ride like a carbon bike. LowCel tells me it's more comfortable than his Zipps, which Vireo says are quite comfortable. We'll see. With Vivian already being really comfortable, I suspect I might not be able to discern much of a difference.

I hope to ride tomorrow morning to get on the road impressions, but given the late hour, that may or may not happen.

One mark of a good review is that you enjoy reading it even when you have no real interest in the product. Nobody writes 'em like Jason! :beer:

As I noted in the long thread (ride report (http://www.bikeforums.net/showthread.php?p=4240654#post4240654)), I went for a ride this morning. I picked my hilly loop (1700 ft vertical in 15.4 miles; Topo says 2000 ft, but I think that's a little silly) rather than my speed loop (700 ft vertical in 18.0 miles) because it has more varied riding conditions.

Overall riding impressions. No feedback on performance since my ride to ride variability far exceeds any equipment contribution to performance. Plus, I was taking it relatively easy since it's been a while since my last ride. The wheels are problem-free, and the minimal amount out of true is not noticable when riding. Even when staring down at the lovely white spokes on the front wheel, one really can't see the amount out of true. Yes, the white spokes are a nice touch. They're a nice visual distraction every once in a while. The ride seems a bit firmer than on my Elan Aero, presumably because the Spinergy appears to be stiffer. (No brake rub with the pads set pretty close to the braking surface.) But still quite comfortable. (Of course, a lot of that is also bike choice, tire choice, air pressure, etc. I run 80 psi front, 90 psi rear.)

Aero impressions. It's an aero wheelset, so it's supposed to hold speed a bit better on flat ground and downhills. Hard to say since I wasn't riding very hard today. Qualitatively, it seemed to do its job on flat ground, but that could be the new toy placebo effect. So today, downhill speed is a better quantitative indicator, especially in the sections where I'm usually coasting. My downhill coasting speed was on the high end of the range of speeds I see on the Elan Aero (24 mm rim, vs 43 mm on Spinergy), but that's highly dependent on wind speed and direction. I hit 44 MPH today with a weak draft from a passing vehicle going downhill on a stretch where I've hit a tailwind-assisted 45 MPH with the Elan Aero (but usually just flirt with the 40 MPH mark). Wind's just too much of a wildcard for comparisons in a short ride. As a side note, my Elan Aero seems to edge out my Easton Circuit even though the Circuit is a bit deeper (28 mm rim).

Bike feel. You know that lively feel of a light bike when out of the saddle? With the Specialized Mondo S-Works tires, this wheelset doesn't have it. The bike just doesn't feel nearly as lively, feeling like a much "heavier" bike than it really is. (This isn't a reflection on actual speed. Just of qualitative feel.) But this isn't because of the weight. My Allez Sport weighs over 25 pounds and has that lively feel when wearing the Michelin Pro2 Race. The Specialized Mondo line of tires has a flattened out shape where it meets the road to supposedly give better contact. Well, this reduces that lively feel. Compared on back to back rides, the Pro2 Race felt more lively than the Mondo S-Works, both being mounted on my Elan Aero. (Unfortunately, the Pro2 Race had a bit of front tire chatter on fast sweeping downhill turns. But only with that wheelset. Not really sure why they don't like each other. The same pair of tires feels fine on the other three wheelsets I've tried it on.) I think a more typical, more rounded shape will return that lively feel to the Spinergy.

Besides that, it seems to be a smoother ride (in terms of speed fluctuations) on flat ground. Maybe placebo, maybe aero helping to maintain speed, maybe just because it's easy to be more even when not trying as hard, I don't know. A bit firmer in terms of comfort, but not harsh. But again, tire choice could affect that.

Overall thoughts. I'm not as wowed by the ride of the wheelset as I hoped based on dog hair's commentary, but I think I will be once I get the right tires on it. I hope to recapture some of that lively feel. I definitely love how it looks on Vivian, though. (But the stickers do have to go. Especially since the alignment of the stickers with the valve isn't the same between the front and the back.) The high sheen of the frame, fork, and bar tape nicely contrast against the matte look of the wheelset, accentuating their respective looks. (With the Elan Aero, everything's just shiny.) I'm not keeping the Spinergy just for its looks, but it does appear to be the one for picture taking.


Need pics with them on the bike!!

Need a good photographer's help. :p After I desticker those suckers...

Gees, Jason, this got be most comprehensive write up on pair of wheels Ive read from someone.
I have set of Xaero lites for my old shimano equipped bike. While its light and probably the most comfortable wheels I've owned, it does feel like there is a lag, not very good for crits. While I like the wheels I probably wont buy a Campy pair. Hope the wheels work out for ya.

I took them around my loop at my parents' place today. 12 miles, somewhere north of 1000 feet of climbing (virtually all occuring in the middle half of the ride, which is essentially a continuous relatively mellow climb), descending the lower quarter of Baldy Rd at the end. I'm still not up to my speed in late 2006, but I did set a new personal best, doing the loop in 45 minutes for an average speed of 16 MPH. (Of course, my previous best is from the last time I rode this route at speed, in November 2005. :o Since then, I've only rode it with my sister.)

More aero thoughts. Yup, these wheels are more aero than my Elan Aero wheelset. No surprise there, seeing as the rims are 19 mm deeper, but I have all the proof I need now. This morning's wind was from west to east, so the best test of aero was afforded to me: a downhill run (along Baldy Rd) into the wind, giving me the highest possible air speed, magnifying any aero differences. Hit 44 MPH (coasting) on the lower portion of Baldy Rd, a speed I normally require a slight tailwind to hit.

Now if only somebody could tell me how to get these in 406 or 451mm sizing...

Whoops. Thought I was in the folding forums. My bad.

How do they compare to HEDs (http://www.hedcycling.com/wheels/recumbent.php)?

Since I was having trouble sleeping, I decided to take a quick picture. Didn't wash Vivian first, didn't have optimal lighting, but oh well, whatever. Unfortunately, the flash makes the contrast between the frame and fork (shiny) and the rim (matte) somewhat muted. The wheelset definitely needs to be destickered...

[edit] And the pic seems to be rather crooked, with my saddle seeming to point up and the top tube seeming to be more angled than it really is. Bleh, whatever... I'll take better pictures some other time.

[edit 2] Yes, I realize standing really close and taking the pic with a 24 mm lens isn't helping things in terms as far as the distorted view goes. Taking pics in a dark, cramped apartment doesn't do Vivian justice.

Hey Jason,

Here's a preview of the wheels sans lettering. Not quite so busy anymore, huh?

That's fine. I hear that carbon/boron/titanium is superior anyway.
