    I have the X lite six ultegra, love it. Price has jumped 500euro and the weight is +/- 5%. For me it was definetly + and came in at 6.7kg on the button. Drop me a PM and if you can meet up for a test ride or once over you can try it out.

    Bought my first disc-braked road bike last year. Have an MTB already. I don’t think there’s much additional maintenance on them and stopping power is excellent. I think lack of wheel rim wear is the biggest benefit to be honest. I’ve worn out so many aluminium rims….

    I don’t rate tubeless as an improvement. Have had so many roadside stoppages waiting for my riding mates to put in a tube in a failed seal.

    Electronic shifting is a far bigger and more useful improvement in my opinion

    Donedeal and adverts are the only game in town second hand really. Market is quiet enough at the minute, I'd say most people have sorted themselves out and are happy to hang on to whatever they have at the minute and just ride it for the summer.

    But there are still some crackin bikes there if you're lucky with sizing.

    New is a tougher nut cos stock in everything is low and they're aren't any bargains. I did notice that Canyon cfsl ultegra. That's a bloody great deal and a magnificent bike by any standards.

    What size are you anyway?

    I'd love disc brakes. Commuting in a lot of damp weather and 105 rim brakes are unpleasant. My pleasure cycling is mostly short jaunts around the dublin foothills and i can feel the limitation of the rim brakes very quickly and they are not at all confidence inspiring.


    In neither situation is the limit tyre grip. I'd take confident, reliable braking over a slight weight gain any day of the week - going faster is nice, being safer is nicer.



  • Registered Users Posts: 4,613 ✭✭✭MojoMaker


    105 calipers are excellent. Stick a decent brake block in there - Swisstop Green or Yellow Flash - and it's all you need for any descent in this country.

    Thanks for your reply. Most manufacturers would advise a 56-58cm or Medium sized frame for my dimensions (88.5cm inside leg, 179cm height). So probably one of the more popular sizes and hence quickest to sell in these times. Age is really slowing me down now, so I need something lighter to help maintain the denial for a bit longer! Ta for your advice, it's appreciated.



  • Registered Users Posts: 4,613 ✭✭✭MojoMaker


    179cm / 88.5cm is some funky offset!

    If one's goal is old school simplicity, the bike has been a solved riddle for a very long time; two triangles welded together with attention to detail in terms of sealing of bearings, quality bearing, wheel design and build etc etc were all possible and available long before the advent of

    • disc brakes
    • electronic shifting
    • internal cable routing
    • press fit bottom brackets
    • innovative cockpits
    • tubeless etc etc

    All of the above add complexity and often reduce reliability and off course the cost to the end user (in terms of purchase price and maintenance) but are required for the continuation of the bike industry.

    As far as I'm concerned they could have stopped at 7800/Sram red 10 speed, but of course it'll never stop. Pretty soon the bike industry will be convincing users they need something else.

    I'd rather if I could buy a replacement 7800 derailleur, 7900 freehub or whatever but that wouldn't be good for Shimano's share price...



  • Moderators, Sports Moderators Posts: 20,190 Mod ✭✭✭✭Weepsie


    I've serious regrets selling my SRAM red 10 speed groupset. Even when it slid across the tarmac it shifted perfectly.


    Anyway. I weighed all my bikes yesterday using a digital luggage scale and will do so again


    Genesis Volare (Reynolds 853-105 5800 with Powertap pedals) 9.1 kg which is respectable I think for a steel bike. I could shave a bit off.


    Argon 18 Krypton X Road (Carbon, SRAM Force Post Mount Discs, 50mm Carbon Clinchers) - 9.1 kg. Switching the wheels to zondas might bring it under 9

    Cinelli Experience - Campagnolo centaur (ALU bike) no pedals on it, 9.3kg (I think)


    My pinnacle Arkose (ultegra disc) was 11.4kg but could get that down a big if I was bothered. and Genesis Tour de Fer (ultegra triple, mechanical disc) was about 15kg but that has racks on it, heavy duty wheels and is by far the most comfy bike I have.


    None of that are true weights either as I didn't bother removing mounts etc



  • Registered Users Posts: 5,839 ✭✭✭fat bloke


    I've 2 full sram red tenners on the go and I'm going to keep them alive and kicking for as long as I possibly can. Only a few short years ago over 7kg was heavy. Reading a review of the new Colnago C68, best bike in the world, all the best components, 15 grand or thereabouts.. and its 7.2 kg or something

    We've 3 bikes in the low sixes and anything over 7 is a winter bike! Manufacturers and reviewers can say what they like about aero and comfort and explain away the extra pork however they like but you can't hide it out on the road. It makes a massive difference.

    I know this started out as a disc V rim but really for me it comes down to weight and cost. If disc braked bikes were lighter I'd be top of the queue, but the industry conspiring to tell me lightness doesn't matter a sh1te anymore, and bigger wider heavier tires on heavier bikes were actually quicker - pissin on my boots and telling me it's raining etc, and charging for all those extra grams at pick'n mix sweet shop rates! :).

    7kg was never heavy. Only for the absolute weight weenies on starbike was it ever heavy



  • Moderators, Sports Moderators Posts: 20,190 Mod ✭✭✭✭Weepsie


    The colnago c60 rim was also a little heavier and around 12 grand too so



  • Registered Users Posts: 533 ✭✭✭Mr. Cats


    There’s a lovely looking Canyon Aeroroad on Adverts at the mo. Rim, mechanical dura ace should suit all the luddites 😂

    Whole lot of bike for the money in fairness




  • Registered Users Posts: 7,947 ✭✭✭cletus


    Just over 7kg? For 3 grand? Pure madness 🤣😄🤣



  • Registered Users Posts: 876 ✭✭✭byrnem31


    That's some yoke. Have to get my deposit back off the shop first before i start looking. I was out on my 2015 canyon today though after turning the handlebars towards me so the grips are nearer to me. I also got a new saddle and its even more comfortable now. Im in two minds now about getting anything at all.



  • Moderators, Category Moderators, Arts Moderators, Sports Moderators Posts: 49,136 CMod ✭✭✭✭magicbastarder


    just weighed my merckx - 6800 mechanical rim brakes, with zondas on it. 7.9kg.

    That canyon is nice but it's not a bargain. That was a cheap bike new - with 105 and the Reynolds wheels it was a bargain at 2600 sterling. So as a used bike albeit with DA on it it's pricey enough imo.

    The current brand new aeroad sl with ultegra disk is available now and is 3900. But it's (imo) unacceptably heavy at 8.2kg for that money.



  • Registered Users Posts: 533 ✭✭✭Mr. Cats


    I think it can probably be bought for c2.5k (price reduced now to 2850). Looks like value to me compared to 3900 for new with Ultegra (albeit disc). Probably this spec if available today would be c. 4.5k new?

    A lot will depend on condition and mileage on frame and components. If it’s fairly fresh (big if), then I think you could do a lot worse for 2.5k.

    But, as ever, it’s only worth what someone is willing to pay for it.

    I have rim brakes on my carbon bike and discs on my commuter ebike. If I was buying a new road bike I'd be happy with rim brakes. With SwissStop pads I can't fault the braking power, although I think my cables need to be replaced as the lever feeling is a bit vague. The only issue I have with rim brakes is commuting, particularly in the Winter the rims would get absolutely filthy and I'd be cleaning them every 2 days.



  • Moderators, Category Moderators, Arts Moderators, Sports Moderators Posts: 49,136 CMod ✭✭✭✭magicbastarder


    With commuting on discs, I found that the rear pads got contaminated quickly enough. To be fair, I was going past Dublin port on grubby enough roads.

    Conversely , cleaning disc brakes bikes requires a bit more care and if a rim brake gets contaminated on the road it's easy to sort. Less so on a disc imo



  • Registered Users Posts: 1,146 ✭✭✭Alanbt


    ill be clinging onto rim brakes for the foreseeable.

    couple of disc brake bike a few years ago and just found them more of a pain than rim brakes. Likely due to first time on hydraulics, but often had issues with noise etc. Rim brakes just so simple to maintain.

    Have picked up a few groupsets to see me through for a while yet.

    But another reason is aesthetics. I just find most modern disc brake bikes ugly. And for me a not insignificant part of the appeal of bikes is how they look. Rim brake bikes just look nicer imo



  • Registered Users Posts: 2,195 ✭✭✭xxyyzz


    Sorry but disc brakes do not "add complexity and often reduce reliability". MTBers have been using them for years and years, not to mention motorbikes and cars. They are extremely easy to maintain and in terms of performance I'd take them any day over rim brakes. If you don't like them, that's fine but some of the unfounded garbage that has been posted about them in the last few years by roadies is frankly embarrassing. The whole safety thing about razor sharp discs was comical when discs are completely blunt and the same cyclists were blissfully riding with bladed aero spokes etc.

    Ask any mountainbiker would they go back to rim brakes and they'd laugh at you. Shimano disc brakes are absolutely bombproof in terms of reliability and performance. Rim brakes do a job adequately and there's nobody being forced to change but the disc brake hysteria of the last few years is ridiculous.


    Disc brakes have more stopping power, better modulation and work as good in the wet as in the dry.



  • Registered Users Posts: 4,613 ✭✭✭MojoMaker


    ...and are largely unnecessary on the road.

    So we're all aligned I think?



  • Moderators, Politics Moderators, Sports Moderators Posts: 24,269 Mod ✭✭✭✭Chips Lovell


    I don't really understand why people get cross or sound offended if someone thinks disc brakes are unnecessary.



  • Registered Users Posts: 1,735 ✭✭✭Large bottle small glass


    I've been using disc brakes on my mountain bikes for over a decade and I'm well aware of their performance and advantages.

    Bleeding brakes, fitting hydraulic hoses is significantly harder than tensioning a brake cable, so yes it is more complex and difficult for an average ROAD cyclist.

    What some SNIP posted about getting cut by a disc is relevant to my post how.

    I don't know why I would ask a MTB rider, this thread is very specific to road cyclist and the increase in weight and cost from an unnecessary technology for most road riders.

    People btw are being "forced" by planned obsolescence by the bike industry, such that rim braked bike market is very much reduced.

    Most road cyclist would benefit from improving their braking technique rather than switching technology; that improved skillset will stand to them irrespective of the braking mechanism.

    My current gravel bike has discs but other than not having to clean rims I managed to never lose control on my old cx Ridley canti bike on really lumpy off road rides; circa 1000m climbing in a 40km spin with lots of 15-20% gradients. Having to re rim after 3k km was a pain but at €30 a rim cheaper than changing bikes and all the waste that goes with that.

    With just road riding I've gotten 40k km from my hplus sons so the rim wear argument doesn't hold much water with me. Lots of that 40k would have been clocked up spins in wet weather in the 200km to 450km range; i.e. I wasn't anal about rim cleanliness.

    If a road cyclist needs disc brakes to stop because of their undeniable advantages he should probably go back to cycling school 🙂

    "If a road cyclist needs disc brakes to stop because of their undeniable advantages he should probably go back to cycling school 🙂"

    That's me :)

    The winter before lockdown (fado fado) was extremely wet, i had poor braking commuting (on XTR V-Brakes perfectly fitted) all the time as the rims were always wet and frequently filthy. I picked up a Boardman with hydraulic discs and am a much happier commuter.



  • Registered Users Posts: 2,195 ✭✭✭xxyyzz


    Sorry, I'm not getting angry that someone thinks they are unnecessary, I get frustrated when I see some of the nonsense arguments posted against them. There was a big uproar over a movistar rider who claimed he got a gash in his leg from a rotor, it turned out the disc didn't go near his leg. Also a team sky rider Owain Douall who claimed Marcel Kittel's rotor put a gash in his shoe which turned out to be more horsesh*t, he hit a barrier at 60kmh and didn't even realise he had cut his shoe until he crossed the finish line but he was still certain it was Kittel's fault. The hysteria from that formed a major part of the backlash against disc brakes but now they all use them and don't give it a second thought.


    I have no issue with someone deciding that rim brakes are adequate for them and I do sympathise that the bike industry enforces planned obsolescence (believe me, it's a million times worse in MTB) but some of the strawman arguments that they add complexity, are more dangerous, don't offer any performance benefits are nonsense. It's just a fear of the unknown. I would say that if you can't follow a youtube video explaining how to bleed a brake then bike maintenance isn't for you. It's a very simple process and changing pads is far easier than changing pads on a rim brake.



  • Registered Users Posts: 4,613 ✭✭✭MojoMaker


    Backlash? That sounds like hysteria alright.

    They add weight & cost, spoil the visual lines, and are mostly unnecessary for pure road use. That's all we're saying!

    Go for your life in mountain biking - they make sense there.

    I have Shimano 105 rim brakes with SwissStop pads - they're still sketchy in the wet. My next road bike will have discs.
