– You’re in the market
for a new set of wheels, and although there are lots
of different types available, you’re probably wondering, should I get some deep section aero wheels, or some lightweight climbing ones? But, although deeps look really cool, I mean they look mint, don’t they, people often wonder, will
they be okay on the climbs? – Hm, I wonder if deep
section wheels can climb? – So in this video,
we’re going to find out if deep section wheels can climb. – Ollie, Ollie, sorry mate. Can I just interject? We do know that deep wheels can climb. I mean, I showed you all on the Angliru. – Yeah, to be fair, you did. But you did use them as an excuse as to not going faster. – Well, yeah, that’s true. But we want to find out if
there’s a big difference, and how much that difference is. So, we’ve come to GCN’s test mountain. – Mountain? – [James] Yeah. At 261 meters high, 1.91 kilometers long, with an average gradient of whopping 11%. – [Ollie] It is pretty steep, to be fair. – Yeah, so the test is, Ollie
is going to do two runs, one on the shallow wheels, one on the deep section rims. Winner takes all. – Winner takes all? – Yeah it’s a competition. – There’s only me doing it, so I’m going to win whatever I do. What are you talking about? That’s a rubbish test. What we’re actually going to
do, right, is ride up twice. I’ll ride up on the deeps, and then whatever power I do on the deeps- – [James] Wins. – [Ollie] I’ll do that power
on the shallow climbing wheels, and then we’ll see how much
the time difference is. So I’m going to keep the
power the same with the Quark. – [James] Yeah, we’ll
find out which one wins. – Bit more scientific that way. – Yeah. – For our lightweight climbing wheels, we’ve gone for a seriously bling pair of Zipp 202 NSWs. These are said to be the fastest accelerating carbon clincher Zipp has ever made, and
for good reason too. They weigh just 1,375 grams a pair, but they’re still 33 millimeters deep, so little bit of aero. For our deep section wheels, we’ve gone very aero indeed. A pair of Vision Metron 81s. These are 81 millimeters
deep, as the name suggests. They’re carbon clinchers
as well, like the Zipps, and they’ve got aero bladed spokes, they’re hand built, and
they weight 1,770 grams, so they’re about 400 grams heavier than our lightweight climbing pair. It’d be interesting to see
if this makes any difference, and if the added aero offsets it. (light music) Manon, how come you’re
not doing this either? – Ah, I can’t climb very well Ollie, so I think you’re probably best for this. – Well that’s a lie. Anyway, you going to time me down? – Yeah.
– Give me the beeps, the GCN beeps? – Beep, beep, beep, beep. (upbeat music) – Now the goal here is
not for me to flog myself. I’m going to try and repeat the power that I do this time, when
I’m on the lighter wheels, so that even at these
speeds, which is slow, aerodynamics does make a difference. So I’m also making a mental note of how I ride the climb, and where I get out the saddle. Some bits I have to get out
the saddle on this climb. And then, I’ll repeat that as well. So this steeper section up here. I’m going to be out
the saddle on that bit. (upbeat music) – [James] Go deep, deep rims, Ollie. – You see, it’s not a race, Hank. I’ve got to, whatever I do this time, I’ve got to do it again. – This the finish line, boff. Oh, good run, that. How’d that feel? – It was all right, yeah. So run one done. Average 310 watts, and did
the climb in nine minutes and 12 seconds. They felt all right. You know, they don’t, I didn’t feel like at a disadvantage, so, we’ll get… You run along, you get the Zipps. – Oh, that’s my cue, is it?
– Yeah. – All right, I’ll see you in a minute. – And we’ll try and repeat that again. (upbeat music) Oh, you sure you don’t want a go, Manon? – No, no, you’re fine Ollie, no. How you feeling for this one? – Well I’m all right. Ah, I’ll get it done. Anyway, give me the beeps, yeah. – Beep, beep, beep, beep. Ah. That’s going to hurt second time round. (unintelligible scream) Go Ollie! (upbeat music) – Instantly, as soon as I did the start, and accelerated with the lighter rims, definitely feel less sluggish. I mean, I don’t think there’s much in it, but you can feel it. It’s weird. So we’re headed up to the
killer super steep section now, so it’ll be interesting to see how they feel on that. Ooh. That should be where there
is most a difference, because it’s where you’re going slowest. (upbeat music) – [James] Come on Ollie, dig in. Dig in, this is for sha-
– So, it’s not a race. I’m trying to do the same power for both. – All right. Looked good though. (upbeat music) – I’ve got the results
on the Wahoo, right? So, just a quick recap. First one, 310 watts. I repeated that. I did 310 watts again. Quite proud of myself. – Yeah, that’s a good effort, but what we really want
to know is the times. – Yeah, so in the first run,
nine minutes 12 for the deeps. – [James] Yeah. – [Ollie] These, right? – [James] Go on. – [Ollie] Nine minutes, six. – [James] Ooh, so much tighter than I thought.
– It’s nothing. It’s nothing, is it?
– Yeah. – Very little. I mean it’s almost within
the realms, I’d say, of experimental error,
but I’m pretty confident that that is about right. – Yeah, interesting. – Yeah, but one thing definitely is when you accelerate off the line, I reckon one of those
seconds was on that bit, when I, just on the start. – Yeah, those are much quicker out the gate, aren’t they?
– They just feel like they do spin up quicker. You can feel it. And on the really steep section, because I held momentum both times, I don’t think there was much in it, but I think if I had
suddenly lost momentum, and had to accelerate at any point, again, I probably would have
pulled out a bit of time with the shallower ones. So, on the whole for me, the deeps win. – Yeah.
– Well they look the best, right, but, I mean, unless you’re just doing
a pure hill climb event, where every second matters
on a climb like this, you’re going to more than get that back on the downhill and on
the flat with the deeps, because the aerodynamics
is just far superior. – Now the big question we ask then, is why don’t all the pros
use deep section wheels like these ones? And there’s a reason for that. A lot of the pros find them
quite stressful to use. Not only do they catch that wind that little bit easier
if you’re in a crosswind, but also if you’re trying to get food out your pocket, then you’re going to have to take your hands off the bars, meaning these are open to
get caught by the wind, and you don’t want to end
up in a hedge, do we Ollie? – No. I think the answer is to
go with a mid depth wheel. Something like a 40 or a 50, like we ride with most of the time. – Yeah, best of both worlds.
– Yeah, best of both, but I mean, come on. They do look amazing. – I mean they sound amazing too. You know that sound. (hums) – Dubstep? – Yeah, or a didgeridoo. – Anyway, good day today. I reckon we should go home.
– Good science. – Go to the pub. What do you reckon?
– Yeah. – Yeah?
– I’ll walk, with these. – All right. Let’s go home.
– It’s a good walkthrough. – I’ll go with you. – Cheers mate, you going
to walk at my pace? – I wonder if they’re coming back for me? It’s getting cold.
