5.5kg Giant TCR: The bike that broke the Everesting world record

Building a bike for an Everesting World Record is all about the balance between weight and aerodynamics. Fairings, rim brakes, modified cassettes and more – this is how Ronan Mc Laughlin put together the bike that just dropped the Everesting world record to 6:40:54.

  1. I’m with Ronan on heel pads, they’ve been holding my Sidi shoes back for a while now

  2. What a nice fella quite inspiring and a great fit on Cycling Tips

  3. Amazing, this hill is close to me and I can tell you it’s an achievement to make it up once.. #respect #donegal 💪

  4. The only thing holding my back from buying a Giant TCR is that integrated seatpost … 😐 . The biggest flaw on a super nice light bike.

  5. I need to lose about 3 stone before I need to worry about removing paint to save weight.

  6. Fantastic record – amazing! And thanks for sharing the bike details – the tyre blowout must have been frightening…

  7. Are those Vittoria corsa g+ speed’s?

  8. Specialized Aethos is this you?🤷‍♂️

    Why no aero overshoes?

  10. 😯 so humble. Congrats to you and your team.

  11. The wahoo bike computer can log the blood sugar? Great!

  12. no stone unturned

  13. yaawwwnnn

  14. Hi, What crank length do you use?

  15. In the salespitch for Concord the engineers thrilled the press conference with the statement; It’s quite aerodynamic…

    I have a feeling this entire video is an understatement.

    Huge accumplishment dude!

    Great supraphysiological effort!!!!!!

    Guzzling sugar every hour
    Big cogs
    rim brakes on a TCR
    monitoring sugar levels..
    pacing to power..

    Someone has been paying attention! xD

    Where the haters at now lol.
    PS: You could have put a 30 up front or a 32 from Absolute Black.

  19. Great video but had to give up watching halfway through because of the stupid crunching sound effect.

    Any thoughts on what difference a hambini bb would make?

  21. I like the sheep wandering up for a look at 10:00

  23. Carbon-works dot com bottle cages are just 6 grams each, including screws.
    And depending on what BB you were using, a Hambini BB might do wonders in a CF frame going up hill / peak torque efforts.
    But. You do not appear to even need all that, mate. Much respect to you!

  24. Giant? I’m not surprised, that’s why I ride a tcr, just not as well😂

  25. I find it hilarious that this thing is only 400g lighter than a commercially available stock build of the new specialized Aethos (with a 2x crankset, disc brakes and paint) and yet every time I mention that I think that bike is incredible simply for being so light weight from the factory I get shit all over (hell specialized frame is 200 g lighter for a customer ready disc brake frame then this rim brake frame was stripped of all paint

    What tyres did you use? They look like Vittoria.

  27. Proper prior planning prevents piss poor performance…

  28. It’s not the bike under the rider, it’s the miles under the bike.

  29. How did he do this without disc brakes? Insane.

  30. How about toilet breaks?

  31. Should’ve cropped the sides of your hair that’s flapping in the breeze. Marginal gains….

  32. I’m pretty sure that Durianrider will soon post a video giving kudos on Ronan’s intention to install a 40-TOOTH CASSETTE.

  33. Duarte Caldeira April 2, 2021 @ 11:57 pm

    Grand Job Lad! 🙂

  34. Silk Dugasts would have knocked at least an hour off.

  35. Aidan Masterson April 2, 2021 @ 11:58 pm

    Jeez marginal gains to the max, but heel pad fail lol.

  36. Cyclingtips will there be a video on the nutritional aspects of the Everest attempt?

  37. Great effort mate. Congratulations. Forgetting to remove those heel pads is a real clanger though. Next time you could consider shaving your head, thats worth an extra 50 grams at least. You could also shave your eyebrows for another 2 grams, your pubes (unless you’re already a manscaper) and clip your nails down to the quick. Clean your ears of any excess wax would save another gram or two and you could use a pumice stone in the shower to remove any excess skin for another 3 grams. Also, next time don’t forget to bleach the fuck out of your skin suit to remove any unnecessary dye and decals, which are also excess weight.
    Oh and take a laxative 2 hours prior to your attempt. Evacuating one’s bowels completely can save up to 500 grams, according to unarmed experts. Thats a potential winning margin
    .

  38. I think Ronan takes himself too seriously 😜

  39. A sneaky sheep on the right wanting to see all the latest Everesting gear @ 9:49 lol

  40. donnybrooklads April 3, 2021 @ 12:01 am

    Congrats Ronan!

  41. Epic

  42. Great video’s Ronan 👌 what about a video about the preparation for the attempt, looking at the specific training, how you determined the correct approach and diet?

  43. Nice bike. I know guys who spend $100s on lightweight replacement components to save a few grams but personally they are 25kg overweight themselves. Amateur bikers are so funny.

  44. Tcr is one of the best

  45. What? You had a needle jabbed in your arm the whole time? Of all the crazy things needed for this effort, this one is the craziest for me.

  46. Bart van de Langenberg April 3, 2021 @ 12:07 am

    Alot of bike brands would pay you dearly to do it over with disc brakes

  47. Soon we will have Giant TCR EE; Everesting Edition.

  48. Great video, however I would love to have learned about the wheels and tyres Ronan

  49. So good, great video, massive effort all round.

  50. Would love to know more about the tyres? And why the rear only lasted a little over 100km.
