 this channel. This is where I do cycling videos both inspirational and entertaining and I do love a deep dive road bike review and all the bits and pieces that go on it which is what this video is going to be about. So a couple of months ago I was out visiting Rob Eaver. He's a GM of SRAM Australia and got a little bit of a project going. The bike I'm riding at the moment Chapter 2 Rare Ray. We've got SRAM One Buy and also some Zip 808 wheels. I'm not riding the 808s now but that's what we're going to be reviewing earlier in the year. The One Buy and the Zip 808s and while I was out there we're talking about rim versus disc brakes on road bikes and I was saying is it true that rim brakes are going to die out 2020 and beyond and he couldn't tell me exactly but certainly confirmed that all the technology is going into disc as you would expect and he's a big fan of disc despite the fact that you know some people out there are experiencing issues including myself so we talked about that and he explained why he's a big fan of disc brakes in this video. I also think there's probably a couple of parts to this first part is this video which is the actual system itself and then Mike one of my subscribers was saying well what about the impact on the bike in terms of its geometry because clearly that changes when you put on disc brakes given the fact that the the force of the brake is in a different part of the bike so what I'm going to do is I'm going to create a part two of this video once I've experienced it myself once I've ridden the same road bike with disc and then rim to be able to truly test it out and if anyone else out there's had experience with that and can tell me the difference in terms of riding experience what they've felt let me know in the below description area or the below comment section and let's get into this video. I want you to tell me the difference between a through axle and a skewer. What's going on? Okay welcome to 2018 just about 2019 this is called a through axle so this is uh we've been riding this on mountain bikes for now 20 30 years and this is what we've been riding on a road bike for maybe a hundred years I've been around that long but it's a long time hold them both up together for me next side by side this is the source of a lot of flex this is the source of uh some issues with threads getting pulled off and you know people like us it's it make them all titanium and nice and light and everything but this is a really important part because your life is basically relying on that thread hang on one fits in the other and yeah you can get maybe a little bit quicker wheel change with this but the point is I want to be safe I want my bike to be stiff and this along with a big hole in the wheel and a big hole in the fork is now a point where it's going to make the bike a very strong stable ride yeah and it's a less aerodynamic though I would say it's more aerodynamic because if you look at this in the bike to answer your question if I put this in the bike here and we're using um still going to put these in bikes so I wouldn't call that slope I wouldn't call that undone aerodynamic like compared to that that hangs out there it is a bit wider it's it's 10 mil wider on the front and on the rear it's about 12 mil wider yeah so it's a little bit wider axle but what that does enables you to run more gears as you can see a lot of companies now going to okay back onto 12 speed we've gone to 12 speed on mountain bike but it's room to grow in the future as well so along with disc brakes along with more gears along with and the more gears it's not a bad thing it gives you more range without having big gaps in between and it also runs the bike cooler as well so it'll run the rear hub cooler it runs everything cooler is it a narrow dynamical I'm not sure every person riding a bike wants every millimeter of aerodynamics but it's not a bad thing either have the skewers been failing at all yes skewers fail all the time right and lots of different reasons happen why skewers fail um you know wheels not in properly you've heard of the lawyer tap scenario lawyer tabs yeah so they were introduced on bikes because consumers did know how to put wheels in bikes properly um so the lawyer tabs were introduced to do that so a lot of the race teams were doing that and filing them off they've been stopped from doing that but if you do wheelie and your front wheels off or you roll over something um your front wheel can come out can't come out with a through axle yeah it's impossible yeah and if it does come out you're actually going to be hanging out the side maybe you shouldn't be walking on this planet if you haven't noticed that if you haven't noticed that exactly so um yeah and for some people the skewers a little bit complicated to work on it you know they understand it's got to go on one side not the other side um you know you how the cam works with a through axle it's either in or it's out there's no there's no halfway so that's the beauty of it so I used a tool on the front so if you come to the back it actually comes with this quick release part here so the quick release can go around anywhere that undoes the axle and then if I want to pull it off I can just pull it off here somewhere with a broken hand that comes off yeah right and this goes in the front here and that becomes that skewer as well and that just sits in there that's it right undo nice and simple I'm weak as at the moment that's all you do Murphy's law nice and simple and that's the other thing was putting the front wheel in all the back wheel unless it's in perfect it's going to rub particularly with this or even rim brake this can only go in one way can only go in perfect so you're going to get it crooked like you sometimes do with a exactly you know sometimes it rubs on the frame or something like that so it's going to run perfectly right yeah that's basically it all right disc versus rim brakes what have you got for me Rob okay lots of things with uh with disc versus rim brakes and a lot of people just compare the two brakes well it's not only about that the rim brakes does a lot of other things it heats the tire up it heats the tube up it heats the tubular up it can deform the wheel if you don't have a right brand wheel my idea is the only thing this rim should be doing is holding a tire on nothing more nothing less if you've got heat a lot of heat going into this it puts a lot of pressure on the tire tube or whatever system you're running that might be fine for once twice 10 times but eventually that type tube is going to fail and you're going to have a sudden blow out because it gets so hot it gets cold again happens a lot yeah and people don't realize what that what that happened i've actually picked up a few people on the side of the road in bike races with that problem they go i don't know what happened my tires are blew out that's maybe things so we take the heat away completely there now we have a global industry standard stainless steel braking surface with a metal sintered brake pad which is it's a dot department of transport standardized braking surface so what that does now it offers less flex down here than up here because the wheels tend to flex a little bit more up here than they do yeah with a through axle the heat is contained right where you want it down the bottom it's not going to affect your ride whatsoever yeah right right and then for me the only time you might love the only time disc brakes are better is when you want to use your brakes all the time in hot conditions dry conditions wet conditions windy conditions they'll always work better what about the sensitivity i've ridden three different bikes with disc brakes and they've all made sort of a meat cleaver sound or rubbing sound at some stage during the period of trial of them four so first thing with disc brakes is they need to be set up properly so i say if you're using Shimano use Shimano pads use Shimano rotors use all that if you're using SRAM use SRAM pads don't use aftermarket stuff yeah try and keep that that's number one and the other thing is that people forget is they need to be running they need to be running properly so what that consists of is check your manual but we say ours you want to get ours up to 40-50 per hour break hard but don't stop break really really hard get the thing really really hot now unfortunately if i live up halfway at the downhill so i've got a bit of a hill so by the time i get down to the bottom of my hill i can heat them up and let them off heat them up so what we're trying to do is get a pad transfer from the organic or the metal scented pad onto the rotor and that becomes a much better braking surface but here's the key thing you don't get your brakes really really hot you know where it's it's 100 degrees and hold your brake on because what that does it puts more of a brake transfer on that one spot so when you go and use that brake again it leaves a high spot so when you stop you'll leave your brakes off and let them cool let them go really cold and then it shouldn't happen after that yeah so there is definitely a braking period and every bike needs to do that yeah and a lot of people you know maybe riding on beach rider you live in a flat area um they don't understand that they don't get that but then they go oh my brakes a bit squeaky they're not working because what happens they've actually polished the surface they haven't got the brake pad onto the rotor yeah right and then they need to match so if you find that it's polished and it's not working you need to replace the pads and the rotor to make sure they work properly or i just take it on a big hill and go and burn them in right does that make it more expensive like longevity wires no no not at all it'll actually last longer it'll be quieter and it works better yeah right okay so none of my brakes squeak none of my bike brakes work and here's the other thing as well i recommend 160 for your average average everyday person they just work all the time everywhere it gives you a little bit more insurance yeah so a lot of bike brands are coming out with that 140 they might be fine until they're not and then you've got a big problem yeah so i run 160s you can see on my road bike here on my other bikes or my gravel bikes and that to me just works yeah gives me a little bit more insurance it gives me a little bit more stopping power yeah because if you're ripping down my on hotham and you need to stop you need to stop yeah okay interesting um somebody that's a fan of rims for you no he's actually time-trollers who doesn't know about riding bikes so i have heard that most manufacturers this is what i'm hearing the industry they're going to stop producing rims anyway by 2020 is that any accuracy in that or you can't i can pretty much assure you we don't build bike frames or design frames at swam um however working with the majority the biggest brands there is no rim brake technology anymore yeah they've stopped rim brake technology doesn't matter the time trial road bike cross bike and cross is pretty much gone long long ago and some of the diehards want to hang on to it but there will be no more technology what are the diehards like the diehards still wanted to run two bikes on their on their cross bikes and they wanted to run v brakes on their cross bikes and stuff like that there's people that want to run carburetors and their cars and and you know um yeah old-fashioned stuff we've moved on from those days so when you get a bike and it's and it's got disc brakes on it i can't believe that anyone would want to go back to a rim brake and if they did that's up to them i don't know
