Have some fun in the travel section.
I travel a fair bit, both for work and for fun. Here’s a bunch of random trip reports and daily trip-logs that I’ve put together and posted. I’ve sorted it all by world geography, in an attempt to make it easy to figure out where I’ve been.
My Photography Gear: The Cameras/Drones/Action Cams I Use Daily
The most common question I receive outside of the “what’s the best GPS watch for me” variant, are photography-esq based. So in efforts to combat the amount of emails I need to sort through on a daily basis, I’ve complied this “My Photography Gear” post for your curious minds (including drones & action cams!)! It’s a nice break from the day-to-day sports-tech talk, and I hope you get something out of it!
The Swim/Bike/Run Gear I Use List
Many readers stumble into my website in search of information on the latest and greatest sports tech products. But at the end of the day, you might just be wondering “What does Ray use when not testing new products?”. So here is the most up to date list of products I like and fit the bill for me and my training needs best! DC Rainmaker 2023 swim, bike, run, and general gear list. But wait, are you a female and feel like these things might not apply to you? If that’s the case (but certainly not saying my choices aren’t good for women), and you just want to see a different gear junkies “picks”, check out The Girl’s Gear Guide too.
Oh man, I’m jealous. I lived in Perth for three months when I was on a project for work several years ago and absolutely loved it. I really miss the Dome for breakfast and running along the Swan River was always great.
Are you planning a group ride of sorts whilst your here in Perth?
Definitely on the radar! Just gotta pick which one! I’m current plan is a group run Wednesday morning nearby at a local park/reserve, but I’ll soon be branching out.
Will also be at the start of the channel swim on Saturday.
A group ride might be a good place to find someone to take all those extra tools off your hands at the end of your stay, assuming you’re not going to be moving around much in Australia. And then, the next time you visit Perth you can just borrow them back, as needed.
Come ride with SPR – see link to southperthrouleurs.com.au
I suspect you’ll love kite surfing, I really enjoyed it even in cold English weather!!
Kiddie swimming lessons are loads of fun! My little one can now actually float around on her back :)
What GPS Headunit is out front in your last riding pic?
Hammerhead Karoo
Serious question, when you do something like kite surfing do you think, ‘I could me another site out of this hobby”?
When I was a content creator this distraction into other fields was a constant battle.
I’ll let ya know once I get in the water. ;)
Nah, for the time being I’m mostly doing kite surfing because I’ve long wanted to do it. It looks like a blast to me.
Minor grammatical note
In Part 4: “going to short”…should be “too”
Thanks!
Ray, two questions on the Shimano Powermeter. I installed mine over the weekend and it works fine but I am not able to check the firmware level as the E-Tube app returns an error, even though after the error the powermeter is listed among the connected Bluetooth devices, and un-pairing from the device settings and repeating does not solve the issue. Second question, do you use the Garmin calibration routine or just align the crank and push the button on the control pod? Coming from years of using SRM’s, I am used to seeing zero-offset values and am curious what values are displayed on your Garmin as I am seeing 150000 before calibration and 250000 after.
Yeah, the E-Tube app is on my to-do list for the morning. I’ll circle back and let you know how it goes.
For me, I’ve been calibrating just using an Edge unit. I also get the same 15000/25000 values. Typically you do get more detail than just those two values. Either you get a torque value back (in the case of Garmin Vector and a few others), or you get an offset value back (Stages/PowerTap/Quarq/many others). Or you get some crazy other value back…but at least the value is somehow validatable.
It’s on my list to figure out…
I’m considering a PM purchase, deciding between Quark DZeroFour91 and the Shimano 9100P. What made you decide on the Shimano? Weight, rechargeable vs coil cell, cost, etc.? The little I’ve seen of the 9100P reviews seem to indicate issues with L/R balance accuracy and poor temperature compensation – any issues in that regard?
I’d like to purchase the 9100P as it turns out to be cheaper than buying the Quark (because the DA chainrings are ridiculously expensive – so the whole crankset + rings + BB adapter end up being like $1500), but not if it’s not going to be reliable and accurate – which is what people are saying about the DZero.
Sorry, I meant “coin cell” and also meant to say people are saying the DZero has no reliability/accuracy issues.
Same “problem” for me. I almost ordered Shimano one (vs. Quarq DzerFour91) but then went through bikeradar review for it and read about issues you mentioned. I wonder how much of this can be resolved by firmware upgrade.
Another problem is that currently Shimano PM is not available in Poland for at least 5 weeks.
Anyway lokking forward for detailed review from DCR. No pressure DCR ;)
Really surprised they didn’t include Bluetooth Smart as an option straight off the bat – I’d really like one of these, but glad I didn’t leap in just yet.
Where and when will you run tomorrow? Would love to join.
I’m doing the 3km Cotto swim on Saturday so will see you at the start.
Well…my plan was the 6:30AM Wednesday run at Thomsons Lake (link to dcrainmaker.com)…but then I just realized while looking up that comment that its actually 6:30PM…which…basically craps my plan. :(
I’m going to have to check out that reserve. Sorry the timing doesn’t work out. The only weekday group runs I can find in the area are in the evening. Looking forward to meeting you on Saturday.
Ha! I had exactly the same brain fade fail last week when installing new chain. This was a Dura Ace chain so decided to Bodge it and put the links back in with the spare pin, then ADDED the links via a powerlink.
I kitesurfed for a few years too. Awesome fun, although almost as $$$ as cycling…
Did you go with the whole ‘get that chain installed now! DON’T YOU KNOW WHO I Am!!?? ‘ approach!? ??
Seriously… Are you now creating a whole storm in the local scene of techie aware triathletes?
Nah…mostly because he knows me by now since I feel like I’m in there every day. :)
I understand 3 head units for measuring power. Pedals, Crankset & rear hub, but why the 4th. For the map?
The one out front (Hammerhead Karoo) is also in test. Since it has some known issues in power meter data collection right now, I couldn’t use it as one of my power meter data gatherer devices.
I actually learned kitesurfing before I started biking, and they’re similarly addictive sports! Can seem like a steep learning at the beginning, but it clicks pretty clickly and is incredible.
Starting to be a few kite specific sports tech items. Woo Sports has an accelerometer based device that measures the height of jumps, and has strava-style leaderboards by location. Definitely seen people using gps watches to track speed, distance, map data. Some interesting camera mounts on the kite itself or the lines. But still pretty limited compared to the bike world.
Does the hammerhead really have that bad of a glare issue?
Mostly no, but get just the right (or wrong), camera angle and it does indeed look like that.
Looking forward to hearing more about the DA power meter, and the kite surfing! Both are things I’d like to try myself, and expect to within the next year or two.
I train in Perth when I am there for work and you definitely need to pick the correct side of the river to ride depending on wind direction! Luckily, Perth has easily the best cycling infrastructure in Australia (it just lacks climbing).
Glad to see you all warming to the local delacacies – Vegemite is definietly best spread t h i n l y! ;)
I’ve been waiting for your in-depth review of the Shimano PM. This is my first choice for a new power meter but had read of some issues around temperature compensation and L/R balance. I have a Quarq on the MTB and this would be my other option. Really happy with the reliability of the Quarq but the Shimano certainly looks good. Thankfully I can wait a little while before buying so won’t make a decision until reading your review and looking at the slow supply of the Shimano units here is Australia, I won’t have the option to buy it just yet anyway.
Hey Ray, is that trainer the JetBlack WhisperDrive Smart?
Yup indeed!
Haha thought so, I just picked up a dumb one very cheap second hand – getting ready for winter training :)
Glad you are enjoying your time here in Perth, not a bad little corner of the world we have :)
Hi Ray I guess there is a limit to tool stuff you can take with you on trips, but I would recommend the parktool rear deraileur hanger alignment tool a lot easier than trying to find a bike shop with the right hanger! and I would think with the amount of travelling you do more likely to need this. Easy to use and as they make hangers out of super bendy material to save super expensive frames from breaking a really handy tool
Abbey Bike Tools Hanger Alighment Gauge – a tad more expensive than the Park Tool, but lighter, and more compact such that it can easily be stowed in checked luggage.
Yes, DA PM testing time…!
What’s with the 645 elevation? It seems to be tracking to the others, just a few hundred feet higher.
Congrats on the upcoming kite surfing lessons. I found it difficult to learn, but once you get through the learning curve, it’s a ton of fun. Stay with it.
Hi Ray, if you like vegimite you must try marmite when on your travels. Oh and it must be 5mm thick so all the flavour comes through.
Woah woah…let’s be clear: I think Vegimite is vile stuff.
The Peanut however, apparently enjoys it.
Good to hear someone else cant abide the stuff :-)

Will you please address the issues with the Dura-Ace Powermeter that were raised in this article, specifically poor temperature compensation and inaccurate L/R power split? Thank you!
link to bikeradar.com
Yup, I’ll be looking into both.
In general though, it’s impossible to be inaccurate on left/right power split and accurate on power. That basically just means that you’re inaccurate on power and by chance happened to be accurate on total power because your left/right power was inaccurate enough in the wrong way to come all the way around to being accurate again.
Left/right balance on these two units is simply doing the math on the sum of the individually gathered power numbers from the left side and the right side.
Is it hard to analyze temperature variation? Do many of the current powermeters not account for temperature variations well?
And, I too was quite confused that if A + B = C, and C was consistent with other meters, how were A and B then consistently inaccurate? Hopefully you can get to the bottom of it!
Temp variation is a tricky one to capture properly, especially in summer months.
It’s a two part issue:
A) You need an actual temperature shift in real-life. Meaning, a few degrees is hard to ‘capture’. You want like a 20*F temp swing
B) Many power meters auto-zero when you stop pedaling (i.e. PowerTap), so you almost want a scenario that doesn’t allow that to occur.
The best possible place to test temp swings in my experience is long mountain climbs in late spring. This is because the top of the mountain is usually balls-cold, whereas the base is usually quite pleasant. You can potentially get about a 50*F temp swing if you time it right, and ideally, without ever stopping.
Someday I want to build a temperature chamber for this sorta thing, but I just don’t have the space right now to do so.
Not trying to bother you at all, just quite curious: Do you know when your Shimano DuraAce powermeter review will be up? Thanks mate!
Within the next few days. I had to split some time a bit for a power meter review that goes live in a few hours for an unannounced product. But been working on both reviews concurrently. My guess is either Friday or Tuesday.
Hey, I live in Perth, how long you here for, any chance of getting together for a ride? Cheers, Damian
How well is etap working together with Sram? I would like to update one of my bikes but I do not want to change the crankset ultegra 6800
thanks
Oliver
sorry need to correct my post :-)
Hi Ray,
How well is etap working together with Shimano crankset? I would like to update one of my bikes to etap but I do not want to change bottom bracket and the crankset is an ultegra 6800
thanks
Oliver
No issues thus far. I had to tweak it a tiny bit using micro-adjustments, but all is good.
I regularly swap in Shimano stuff into my eTap bike and vice versa. No real issues once you get it nice and tuned.
Perfect, I will go ahead and maybe change the bb and crankset at a later stage for a cleaner look.
Ideal! I’ve got a 6800 groupset, but no internal routing on my bike, so no Di2.
I have been looking at eTap, but wasn’t sure how it would get on with the Ultegra groupset.
How do you find the brakes? Some forums say the levers have different pull ratios…
No issues with brakes for me. Though, I’m probably not the most picky there. As long as my bike stops before I run into something, I’m generally satisfied.
Ray,
Does Shimano have any plans to support power through Bluetooth or are they just going to use it for setup and maintenance?
They say they’re going to support it this year sometime.
Hello Ray, I loaded your files and analyzed with WKO4. L / R looks fake vs V3 and shimano powermeter underestimates a lot power vs Powetap G3 and V3. It should be very close V3.
Not sure I follow on what you mean by it looking fake.
I dug through today’s ride, and things on balance nearly perfectly mirror Vector 3. Some slight second by second variations, but overall very close. The G3 does seem to be reading a bit high however. link to analyze.dcrainmaker.com
Thank you for link, yes i mean wrong balance for shimano. Sunday : Avg L/R: 49/51 shimano vs 44/56 V3 . Today: Avg L/R: 45/55 shimano vs 47/53 V3…
I guess the challenge is knowing which power meter balance is right then…
I think balance on shimano is a little wrong. Shimano vs powertap P1 give for me : 47/53 shimano and 50/50 for P1 at 300w ( FTP for me) . Same P1 vs Rotor 2inpower was very close. 50/50 or 49/51.
Where is the quokka selfie? Surely you are as popular as Roger Federer?
Cool. Is that with Shimano callipers or SRAM?
