#askgcntech Hi Guys, I'd like to know if you can confidently recommend from your own personal experience any shoe covers that are actually water proof (not just 'waterproof' as stated by the brand). My shoes are Specialized Torch 3.0's and I've tried multiple shoe covers that claimed to be 'waterproof'. After one or two rides in properly wet weather, my feet get almost as wet as when I wasn't wearing them. I have also taped the little vent on the bottom of the shoe shut to prevent water from getting in there, and it didn't prevent them from getting soaked. Thanks!

Hi Guys, James here in Northern Idaho, I was wondering if a carbon frame gravel bike (Salsa Cutthroat), could handle a kickstand. I know it's not 'cool' but there's something to be said about accessing your frame/saddle bags on an upright bike. I'm doing the Divide in June and thought I'd ask. If so, are there certain types/specs that I need to look at? Thank you and thank you for your channel. James

I completed a 12hr 235km/4500m Aussie sportive last weekend; the temperature was 35c/95f. Everyone was reapplying 50+ sunscreen at the rest stations as a necessity. Looks like it was 50+ with Octocrylene…. Further GCN research and identification of suitable internationally available sunscreen for endurance riding would be awesome.

[@andrewmcalister3462]

In terms of cancer risk, a 12 hour ride without sun protection is much higher than that posed by the breakdown of octocrylenes. If that was what was supplied on 3 Peaks, then you are better off using it than not. That said, if there are better sun screens out there, it is worth investigating them.

[@mkobus7034]

"be kind to your knees. You'll miss them when they're gone" - also relevant! Aussies should be better at sun protection, but whether the excuse is "i don't burn, i tan", "one application is enough" or "it feels yuck", many often aren't. I've had misses and paid in red stinging skin, so i use arm sleeves or long sleeve jerseys just about exclusively (they're often short and you need to get your wrists with extra protection) and have tried to use leg sleeves as well (haven't found many non-thermal ones, and they are sized for slimmer twiglets), but they sometimes bunch up and chafe painfully on longer rides. The weight obsession in a section of road cycling could be part of it - even on longer rides, cyclists only carry their 'essentials' and there's not room for more than a banana or so. Sun protection often isn't considered as essential as saving 100 grams over 100 km - not a great holdover from the competitive stat 'one-upper' mindset.

[@magysoeldner6074]

Thank you for answering my question! :) And also thank you all the people sharing their experience with indoor cycling here! It really gives me a nice overview of the options and all the pros and cons tied to them.

[@robertlight2370]

I know of a couple that share an indoor bike. They have a frame/stem size that's in between what would be perfect for them - but close enough. But they have separate saddles mounted on separate seat posts, and each seat post has a collar to mark the right height. So they simply swap over the entire seat post and saddle, using a QR, for each rider.

[@urouroniwa]

I live in country with a relatively hot summer and I'm also at about 35 degrees latitude. I cover my skin with cloth. You can buy arm covers that are 100% UV protecting and I've found that they aren't really warmer than bare skin because they are always soaked with sweat. You can also wet them at the start of your ride and the first 20-30 minutes they will provide amazing cooling. For longer rides, I'll periodically just wet them down when I'm refilling my water bottles. You don't need much water. Having said that, it's still a problem for the face, neck and legs.

[@gcntech]

That's a great tip! Have you used it for long rides?

[@urouroniwa]

@@gcntech Yes. 5-6 hours, anyway. It's actually really common in Japan, though it's sometimes hard to find arm covers in larger sizes. Some people I know wear leggings all summer long but I've never found leggings which breath well enough for me. Pearl Izumi makes "Sun Sleeves" which are designed to keep your arms cool. I just now noticed that they also make "Sun Legs"... I'm going to have to get a pair and try them out...

[@wilkins2ca]

I've had melanoma on my forearm. Since then, I wear light long sleeve jerseys or sun sleeves. I don't race, but haven't noticed a big difference in heat or performance.

[@gcntech]

We know of riders that use arm warmers all year to protect the skin too 👀 Do you feel it makes you feel safer when out on long rides?

[@MsTatakai]

Welp... i use only slim long sleeves shirts when riding on winter or summer... its my way to dress and its always better for cooling... if you want just strip up the sleeve and you got a long T-Shirt... if you get cold than unstrip the sleeve and now you have a shirt =P

[@wilkins2ca]

[@paulgrimshaw8334]

Anyone needing a complete answer should consult the Aussies. They’re masters at sun protection. It’s almost cultural for those folks. Perhaps our hosts could start their search with the host of Zero Friction Cycling. He might be able to recommend an Aussie expert (maybe even at the Australian Institute of Sport).

[@gcntech]

Hahahah we'll get back Adam back on for this 🤣

[@mkobus7034]

Some are masters at sun protection. Some take the larrakin spirit a bit too far and swear "she'll be right, mate" while doing nothing about it. It needs to be more endemic in outdoor pursuits, including cycling, as much as getting into awkward form fitting lycra has become.

[@clinlashway9147]

I much prefer to use mineral based sunscreens. First off, they just work better at blocking the sun. And because these literally work by reflecting the sunlight, rather than converting it, I believe my exposed skin runs cooler. In other words, the energy from the sun is reflected off my skin rather than being absorbed and therefore heating my skin. The mineral sunscreens also do not have the cancer risk of the chemical sunscreens. As far as possibly interfering with sweating, I have no idea, but have not found that to be an issue for me. Also, how about a link to the video Ollie mentioned.

[@ChrisCapoccia]

[@robertwaldren6206]

My wife and I ride the same model gravel bike which we use on our trainer, but hers is a small and mine is a large. Even with thru-axles, it takes me around 4 minutes to swap the bikes, or 5 minutes if I have to install wheels on the one being removed from the trainer. To me, that is a small price to pay to ensure the right fit while avoiding pain and injury. Keep in mind that we don't move around as much on a trainer as we do riding outdoors, so I think that a poor bike fit becomes even more of a problem indoors.

[@Shel8008]

Probably the highest SPF in the market and good for sports - Sunplay SPF 130, spray on alcohol sunscreen, coating is thin, doesn’t clog, good on sweat and reef safe.

[@steve_m.3403]

On the subject of swapping bikes on a trainer, when my wife and I both had 11 speed drivetrains with QR’s, we just swapped out bikes in a few minutes time. However, when I switched to a new bike with SRAM 12 speed and thru-axels, I found the best solution to be a Kickr Roller and sold my Kickr. It’s trivial to swap out bikes but does require both bikes to have power meters.

[@gcntech]

Ah interesting! Great that Wahoo have to options there for you to swap out 🙌 No room or two trainers?

I have several sunscreens that are advertised as "reef friendly." it seems that the chemicals banned din Hawaii are Oxybenzone and Octinoxate. Octocrylene is not explicitly banned, so it seems to be the substitute used in a lot of sprays and creams sold in the US. I have some newer tubes and sprays from a variety of brands and they all contain Octocrylene. One even says "compliant with HI SB2571." It seems staying away from Octocrylene is harder than we thought...

[@coachjohn]

Living in Florida sunscreen is a REALLY important piece of kit. I use one from SolRX that was developed for Ironman racing. They have a different method of blending the ingredients that cause the SS to encapsulate the skin cell and dosent wash of without using soap. It lasts all day with no issues. I am not associated with SolRX but will use nothing elas...and it sprays on.

[@Francis-ld2yi]

For a shared indoor trainer bike, you can try having 2 separate seatposts and saddles. Setup one for your saddle height then the other for your partner. In this way you just have to swap out seat posts with saddles already installed depending on who’s going to use the bike. Make sure to mark each seat post height with tape or whiteout , and try to get a quick release seat clamp for faster swapping.

[@wuzihuzi]

Or just get good at swapping out the bike. It's not hard 🤦🏻

[@gonzalezgaraypablo]

Are sun sleeves better than sunscreen?

[@mommamooney]

The husband and I had to share his trainer and my bike for a few weeks. Zwift was sending me a replacement Hub and UPS lost it. We couldn’t bike swap because his bike is only an 8 speed and mine is 11. We just changed the seat height. Wasn’t ideal (my bike is 4 sizes smaller), but it worked until UPS got their act together and delivered the replacement of the replacement Hub. I wouldn’t want to do it long term. The seat wasn’t ever quite set the same and caused discomfort

[@Steve.M]

I’ve used Riemann P20 sunscreen for several years. I was attracted by its sweat-proof one-application-lasts-all-day feature, and so far it seems to have offered good sun protection. It’s a pump spray, clear liquid. Is this an example of the alcohol based type that Ollie favours? Anyway, checking their website now, I see that some (but not all) of their products have a new ecologically improved formulation that does not contain octocrylene. I’ll need a new bottle this spring and will definitely make sure to try this type.

[@stuartmisfeldt3068]

A second trainer is probably cheaper than a new bike that has to be bought and then adjusted for not only seat height but stem and bar reach and depth. Or buy a Zwift or Kickr Core with hub 1 and sell your old trainer.

[@megg2004]

I have sensitive skin and am a heavy sweater. Think brand sunscreens don't cause any rash and it stays on even during long rides. It is mineral based and comes in both a sqpray and lotion. I'm not a huge fan of the spray, though, it tends to clog in the nozzle. :oldmanyell:

[@jaydicenso]

@romanluu Blessing in disguise: Since lots of serious riders are shopping for thru-axel wheels these days, you can find some pro-level QR wheels from a few years ago for a great deal! Just make sure they are compatible with your brakes (disc or rim).

RE: Sunscreen cooling. Dr. Bridgewood, because I'm a hippie from California, I've avoided the "chemical" sunscreens for ages, always opting for the mineral ones, you know, because minerals are "natural". Hippie mindset aside, the mineral sunscreens work because they reflect UV while the "chemical" sunscreens work by absorbing the UV. Now it might be negligible, but it seems that UV reflecting sunscreen would reduce the amount you are warmed by the sun compared to absorptive sunscreen. Thoughts?

#askgcntech Hi Armando and Ollie. I'm considering going for wider tyres, currently rolling on 28mms, but I'm concerned about the aero penalty of doing so, wheels being optimised for up to 28mm tyres. So, what I've started considering is going wider at the back (to say 32mm) while keeping 28mm up front. While this seemed like a great compromise, i'm now concerned that the larger tyre at the back would also bring up the entire back end, messing up angles and my position overall. Is this a real risk or am I being paranoid?

Maybe a long sleeve wicking type shirt (hat, neck shield, etc) that's not heavy, hot, or bulky is a better solution for sun than chemicals. What physiological effects do these chemicals have on the body, and its ability to tan (a natural response to UVA/UVB), it's ability to correctly monitor internal heat, and the lack of immune response to harmful chemicals on the skin? It's one thing to be exerting energy that causes someone to sweat, but as motorcyclists have figured out in the non-exertion world, covering up the body to sun and heat exposure works better than leaving it all out in the sun and wind. A controlled micro-climate is more functional than having hot air and sun baking your hide.

I don't know about the ease of getting the bike on and off the trainer.. I hate having to take my 2023 Trek Domane SL5 on and off the Kickr trainer (being specific in case someone else has this issue or can at least confirm this issue). I don't know what they did when designing that bike, but it is an absolute pain to get the thru-axle lined up. There doesn't seem to be much material for the dropouts to sit on the trainer's thru-axle adapters, so it is a faff of shifting the bike around until it finally starts threading (hopefully without cross-threading).

#askgcntech Hello GCN Tech, Which tires do you choose for climbing- lightweight with higher rolling resistance or heavier with lower rolling resistance?

I tossed all my "oxy" sunscreens and just use zinc/titanium based stuff now for myself and the kiddos

Asking a sunscreen question on an English cycling channel is like asking a Floridian how to build an igloo.

Any bike can be a gravel bike 😉

Those string bikes

I live in South Africa so plenty harsh sun, since I have changed my diet to carnivore 6 months ago I have not had the need to use sunscreen even through a very hot summer this year. I just don't burn anymore. My work has me outside much of the day through the midday period as well.

Less expensive too buy a second KIKKR than buy another bike!!!

[@user-sz8qg7ci9f]

BUY THE 520'S they will outlast the bike, the shoes and you can hand them on to your grandkids.

[@stevemc1790]

No not belt bikes@

[@TigerChunLee]

I agree with having one bike on a trainer between two different people. If you had different bikes set up you may have to chain the cassettes every time. All I do at home is have a dedicated seat and post for myself and my wife.

[@gcntech]

Hi, thanks for the comment. How is the reach on the bike if you share it? any issues? Cheers 👍

[@TigerChunLee]

@@gcntech my reach is fine, my wife has to stretch a bit. but she is too busy playing on her phone to notice it really.

[@timtaylor9590]

aluminium and titanium isnt good either

If Ollie is smart why is he working there?😅

Last question on sunscreen was just a ridiculous showing off from "blabla whatever"

[@rangersmith4652]

Sunscreen is a royal PITA. Humans evolved on Earth, where there is sunshine. Do the math.

[@WellValUa]

well, I sadly evolved to get red painful skin after 30 min in the sun

[@MrPharmageek]

We also didn't survive long enough for sun damage or skin cancer to be much of a concern for most of our history. I'd say putting on sunscreen isn't much to ask in light of a life span more than double our distant ancestors.

[@clinlashway9147]

The math was that during human evolution life expectancy was 33 years. Humans simply didn't live long enough for this to be a major issue. But you do you.

[@rangersmith4652]

@@clinlashway9147 That's quite a broad brush with which you paint.

Visit your local hospital and speak to some of the patients with skin cancer
