As a CAD designer, this shouts "I'll just throw this rough volume around the internal components for now, and come back to smoothing it out and making it ergonomic / look good later".

Except they never came back to it.

DC's just gone up. https://youtu.be/LPbvpFmFKu4

EDIT: after watching this... yeah, it's a bit shit.

Is it even true that your power output in TT position can ever equal your output on hoods or in drops? I don't think that's something I've ever heard or read, so not something I've been chasing. Just accepted.

I figured that yes... there's a drop in power output, but you're still working as hard as you would be if out of position. So by improving your power in position; you're actually improving your fitness, and thus your out of position power ftp improves.

Wouldn't ones power capability in TT position be more a function of position? Hip angle, position over BB, comfort etc.

But what you loose in power through the bike, you gain back twice over (or more) in aerodynamics. So it's well worth the 10-15% drop.

Probably something in that... I could imagine the majority of the developers being runners, for which 5k is a pretty standard interval length.

Presumably you've got an auto-lap set for every 10miles.

Quite right, suitably admonished.

Thanks.

There's a chap on here that does splendid di2 component repairs is there not?

Can anyone remember their name?

"I don’t want to go and just get another tracksuit. I’ve got four tracksuits already – I don’t need another one."

He seems to be taking it well.

Is there any way to adjust intensity mid workout in a similar way on either of these devices?

Yes... at least there is on my Garmin 840, so I assume it must be possible on other devices).

I have a profile for the indoor turbo bike (created from the INDOOR template) that is set to connect to my smart trainer. Selecting that profile from the list when starting an activity throws up a menu to select stuff like FREE RIDE, SET DIFFICULTY, SET GRADE, TARGET POWER etc. I select that last one, input my target power, and pedal away. Once on top of the gear, it's starts tuning the resistance.

It's basically ERG mode via the Garmin. I've found it's not quite as responsive as Zwift's control, and the tolerance range it allows before it adjusts the power is wider... but it works well enough. You may even find yourself offset from you target (eg you set 200W, but are working consistently at 210W), but just factor that in.

That difficulty offset that Zwift is really useful isn't it? The alternatives to Zwift I've tried recently didn't have it (really only Whoosh tbh), hence why I experimented with using the garmin to control ERG mode. Interested to know if its in any of the others (indievelo, rouvy).

This stem looks the nuts, with that flat top surface all the way to the front. Looks so much cleaner than the screw boss bumps on pretty much every other stem.

I've never understood why other stem manufacturers don't do something similar.

I want someone who knows what works and can suggest stuff to test quickly and get it done with minimal external variables.

Do wind tunnel sessions do that though? Dowsett's recent video series seemed to suggest that they simply follow the test protocol you want run, operate the machine, and provide you with the results.

It was implied that it's up to you to decide if you want to go higher in the stack, lower, longer, shorter etc... they just provide you with the numbers/graphs and tell you it's quicker or slower. And moreover, it's up to you (or your mechanic) to make those changes to the bike... eating into testing time.

Xav from Aerocoach discussed this on a podcast recently and said exactly the same thing. He can't make suggestions on position or geometry, because he'd be using information gathered and paid for by other riders in his wind tunnel... it wouldn't be fair.

Why don't you just swap the CX pedals over to the Venge?

Without specific guidance on how event organisers are expected to enforce this rule, or how strict they are to be about DQing riders they suspect of exceeding a 20mph limit; this feels like a box ticking exercise by the CTT to cover their own backs.

They can now hold up their hands and say "nothing to do with us, we told them to slow down", and has shifted responsibility to deal with "public outrage*" onto event organisers.

(* their words, not mine.)

Reports that GCN+ service and app will be closing on 19th December :-(

EDIT: just seen full post in ProCycling thread.

If using an FTP value as the basis of a medium to long term training plan, would it not make more sense to do a longer 20 min or 1 hour FTP test? You may have to do two or three to get pacing right, but it yields a much more accurate measure.

Ramp tests are apparently notorious for overestimating FTP.

I wouldn't cycle in that "cycle lane".

I did a duathlon at the weekend... 5k/20k/3.5k.

As someone that does a lot of TTs, I was in the top 5 or 6 on the bike portion. But it sure was demoralising seeing everyone running away from me from the start line.... there I am blowing gauges to hold 5 min/km, while they're all doing 4s and 3s. I was close to 7 mins behind top 10 before I'd even gotten on the bike.

I'm not an unfit guy, but as a non-runner it blows my mind how folk can run that fast.

I used a 520 to death, so immediately jumped at this gen when it was released earlier this year.

The 540 and 840 are exactly the same, other than a touch screen on the 840. They have the same button layout. So if a touch screen is not something you're interested in, then you can save £100 there. Personally, I'm not sure how intuitive the interface would be for button only, but I'm sure it's perfectly possible.

There's a lot on the x40 that I don't use. The personalized trainer system I don't pay any attention to, live segment notifications, a few other things. But that's ok... no harm them being there.

I've used mapping, and it's perfectly serviceable.... shows the map, gives me directions, tells me if there's a sharp hairpin or busy road up ahead. The climb pro works well, detailing elevation profiles of hill climbs on a pre defined course... it's nice to know what's coming up. The live version of that (when not riding a course) I found a bit hit and miss... sometime it wouldn't give details of a significant hill I'm actually on for some unknown reason. The flexibility of data screens is pretty good, and the IQ store (crowd based apps) has some interesting tweaks one can add (despite it being a shit show for discoverability)

Battery life has been excellent, but I was used to a 520 what lasted for like 3 hours before 0%. I dunno.... 15+hours I guess. I did a 24 hr race round Nurburgring with only minimal topping up.

Can't authoritively comment on the solar version, but I'd hazard that unless you're in a super sunny climate and doing multiple day ultras... it's probably not worth it.

Obviously I've got buyers biased here. I like it well enough. But it is expensive... £350/£450 is a lot for a bike computer. I rationalised the price in my head; as it really is the only one I use and I used the last one for 8 years (well beyond it's life time). If you've other edge's you intend to carry on using for other types of riding... the 540 way overkill. Especially only for commuting or sunday cafe trips. You could easily pickup a 530 for a shade over £200 (although even that's probably also too pricey in these hard times).

And I'm sure other brand of bike computers do similar for less. No idea how polar, wahoo or hammerhead compare feature/price wise; but I did look briefly at the Magene computers as they're super cheap in comparison. Worth investigating at lease.

TLDR: I dunno, I like it... but it's expensive.

Not sure Upnor Castle is really worth the diversion through Rochester... but at least the Tudor Rose pub next door is half decent for lunch

Pesky things birthdays... popping when you least expect them every single year.

I'm not particularly familiar with home 3DPrinting materials.... but if one was going to those measures for aero gains, surely they could have stretched to a black filament for aesthetics?

They agreed a 10 minute poo stop, but Nick cracked on.

Dick move?

I guess only if he said he'd stop, and then didn't.

If you're using a cycle computer, you may be able to pair your watch to it. Not something I've tried personally, but feels like something one should be able to do. (I think Garmin does this via 'Extend Display' mode)

I wouldn't recommend constantly looking down at a wrist watch while doing a TT.

Pacing is the key thing with TTs, and knowing what you can hold consistently is crucial. That knowledge will come with time though, the more TT events (at the same distance) you do, the better attuned to your ability/numbers you'll become.

Power meters are obviously king, then Heart Rate monitors. They'll give you objective numbers (assuming you've done a test to calculate your FTP or worked out your HR zones from you Max HR). After that, you can use Rate of Perceived Exertion to score how hard you're working.

One really basic and easy method to gauge effort is to be constantly asking yourself 'Can I hold this pace for another X miles to the finish?'

• If your answer is 'no', then you're going too fast.
  
• If your answer is 'yes', then you're not going quick enough.
  
• If your answer is 'Oh god, I don't know, this hurts, stop asking questions', then you're probably going just about right.
  
  
  

Any knowledge what happened to Tony Hauser (I think) to cause him to stop for nearly a week (the big horizontal line at 85hr). Amazing that whatever it was, he's started riding again, and isn't in last place. Rooting for him to see how high up he finishes (if he finishes)
