Focusspeed1 Posted August 20, 2020 Author Posted August 20, 2020 How does one create a little voting poll thingy in a thread? Can any1 do that? Would love to see the outcome tho... Disc? Rim?
HdB Posted August 20, 2020 Posted August 20, 2020 Well, I switched to a disc road bike in Dec, simply because that was what was available at the shop for a good deal when I stripped my moer for my old bike.(Also meant a switch from Campagnolo to Shimano after any years). And to be honest, it really doesn't make a big difference for me. It still brakes, changes gears, and goes as fast as my fitness allows.So, for me, the answer to your question, Disc or Rim: either. Whichever you like the look of the most when buying Pikey 1
Chris_ Posted August 20, 2020 Posted August 20, 2020 I wish biking was more simple There will always be something better, and always be something worse, and no matter what there will be opinions on all sides. I doubt/hope this isn't the last bike you'll ever buy so its not actually such a momentous decision. I'm certainly in the 'intangible' bike buying camp. What brand do you like? What shape do you like? What can you buy that'll make you desperate for a ride every time you walk past it? The rest is like an iphone - as soon as you buy one its already outdated. DieselnDust 1
EddieV Posted August 20, 2020 Posted August 20, 2020 (edited) How does one create a little voting poll thingy in a thread? Can any1 do that? Would love to see the outcome tho... Disc? Rim? My vote will be disc. I'm in the same position. Decided to go disc (disc brakes have been proven with MTB-ing and gravel). One of my main motivators is carbon wheels, should I one day would want to go that route. The other is the cost of switching from rim to disc. It's not a simple upgrade, it involves wheels and a couple of group-set components ... and frame ....... my commuter (gravel-bike) is disc, and I'm very happy with her stopping power.

Schnavel Posted August 20, 2020 Posted August 20, 2020 Hi Chris, to be honest there are a few comments i havent read as it was too insightful... Dunno if that makes any sense at all... I just checked in so now and then to see if i could get a plain and simple... Rim, or disc... I am appreciative of all the advice.. But as mentioned this just confused the hell out of me and decided,............... To just carry on with wot i have right now, wait and see how things play out in the next 6 mnths-year. Mayb just upgrade to a carbon frame for now and eventually when there is more clarity. Do a complete upgrade or new purchase... Buy a bike that makes you want to ride. If that bike has rim or disc brakes, costs R10k or R100k, is red or blue or black, buy it, ride it and enjoy it. It really is that simple!
Jewbacca Posted August 20, 2020 Posted August 20, 2020 I have a 2014 steel disc road bike. I love it. I do sometimes pang for something lighter and plastic but at 75kg the weight difference is a bit pointless. If I ever felt the need, the one thing I would up grade is to 38mm carbon wheels. I have 30mm deep alu wheels on and they do the job just fine for a hacker like me. I think as men, we over complicate everything. Whether it's bikes, guitars, running kit.... A friend of mine put it beautifully. If it works and you can use it to get better/stronger/faster, then it's perfect. Riaan H and DieselnDust 2

Getting a new bike has made me want to ride more than everhahahaha I used to be the village bicycle but I'm married now! Yeah, I hear you, but I don't struggle with motivation. I'm not really a 'couch' kind of guy. All this talk made me look at the classifieds and there is a 2017 52cm Spez Roubaix that is affordable and rad..... I am now wondering if I could cover the cost by selling some other bits and bikes... hahahaha

Yeah... I've had other bikes, but gone back to my steel disc bike. BUT that Roubaix looks like it has my name on it, is in my size and will match my mountain bike...... Now to find some money
DieselnDust Posted August 20, 2020 Posted August 20, 2020 I take it you all saw that discs are not infallible?https://www.cyclingnews.com/news/giro-dellemilia-pellaud-left-with-facial-injuries-following-brake-failure/ Yes I read that this morning. Surprised its taken so long. These guys are going 80-100km/hr downhill. Bicycle disc brakes are designed around converting kinetic energy to heat but based on MTB technology.Considering that velocity is the main driver in kinetic energy (hence its name), by travellng twice as fast they have to absorb 4x the energy!!Yet they are mounted to flimsy mounts, use a smaller caliper than a MTB and often use smaller rotors than an Mtb. Roadies also brake longer than Mtb riders do.The bike industry has taken a tool designed for mtbs and pasted onto road bikes and expect the masses to buy them because "better longer lower slacker faster". What i've picked up about road discs is that the pads require much more frequent replacement than for an MTB.The brake fluid needs more frequent replacement because its being oxidised by greater heat build up.this = more maintenance. Maybe for guys just out riding their bikes disc are ok because at least they have consistent braking. For peeps riding at higher speeds, riding the descents at greater speed, maybe not so good. I'm betting we'll see a lot more brake failures till the industry goes back to the drawing board Captain Fastbastard Mayhem and splat 2

IMHO this is one reason why you can't draw accurate comparisons/conclusions between what the pros ride and what is suitable/optimal for weekend/social hackers. The way the kit is used is just worlds apart so most data extrapolated, especially at the extreme ends of use is pretty much irrelevant for most people and most if not all of the roads and passes in SA. I ride around the peninsula. There is not 1 descent that I tests my equipment. There are plenty of examples of pro's with brake failure long before disc brakes made it onto the road. No system is infallible, especially at a level or in places where they are constantly used and pushed at the top top end of their design spec. DieselnDust 1

Take that car to the track and within a few laps the brakes are cooking (been there done that). But take a track car and drive it like an amateur and you shouldnt have a problem, stick a skilled driver in that track car and overheating brakes are not unheard of. What I'd like to know, how would rim brakes have faired in Pellauds case ?

Exactly! but the wear issues I'm seeing is with a few lightweights. Sub 70kg but fairly quick (3hr Argusts) Edited August 20, 2020 by DieselnDust Jewbacca 1

Is that not the point, most people will never need the braking of discs? So when choosing a road bike, disc or rim does not make an actual difference. Just one is heavier than the other and one looks nicer than the other. Jewbacca and DieselnDust 2
