Bikes modified (or not) for 'everesting'

For me, everesting was also ‘about the bike’ as I love modifying stock bikes.

I chose the lightest frame I had – a carbon road frame.

Drive train / transmission: really, really, low gears: 11-46T, 11 speed cassette (Shimano XT).

This meant using an 11 speed mtb shifter (Shimano XT) and a rear mech (Shimano XTR) that would clear the 46T cog that I used once the legs turned to jelly (fairly soon in the procedings).

Power (the term is loosely used) was transmitted via an mtb crank (Shimano XT) with a 32T single chainring. As the crank was designed to fit mountain bike bottom brackets (and I was using it on a road bike), I had to use a headset spacer (Aerozine) as a shim to get it to work.

Other mods include: a flat bar (Ritchey WCS), flat bar brake levers (Shimano Tiagra) that were compatible with rim (gasp) brakes (Shimano Ultegra), ‘anatomic’ rubber grips (Bontrager) and (horror) bar ends as well as a 150mm stem (Ritchey WCS). The saddle (Fabric Scoop) was ‘the wrong size’ according to the measurements of my ischial tuberosities (@$$ bones), but it suited my bum (critical in a 24 hour plus ride).

Wheels: reasonably light clinchers (Shimano Ultegra) shod with 25C puncture-resistant tyres (Continental Gatorskins) and contrary to popular trends, the tyres were inflated to an eyeball-rattling 120 psi.

Pedals: ControlTech ‘flatforms’ - broad mtb pedals with plastic toeclips and leather straps (both Zefal).

Hydration: a single carbon bottle cage (Arundel Mandible) with various small(er) cycling bottles – a quarter full of ordinary water.

Second image is of the bike during the 8848. Also visible in the image are very tired legs and some junk food (banned by WADA).

Good effort.

FWIW you don’t need a headset spacer to make an MTB crank fit a road BB. Shimano makes 2.5mm spacers specifically for the purpose and includes three of them in the box with a new MTB crankset.

I use 68mm T47 BB shell inserts from Paragon (they don’t make them in 73mm) so I use the Shimano spacers when fitting one of their MTB cransksets.

Thank you for the (cycling) tip! :grinning:

What shoes did you use, throwing away cheap efficiency Watts if the answer is running shoes

Here is my bike, and a very tired me after everesting Donner Pass Road near Lake Tahoe.
everesting mods:

  • extra computer mount for dual computers (wahoo and garmin)
  • 42t sprocket (up from my normal 36), MTB derailleur is standard for me :slight_smile:
  • smaller saddle bag - I normally have a bigger one with lots of junk, just had the bare minimum here as I was riding alone.
  • missing from the pick: top tube feed bag.


great effort @Ashok_Captain. where did you complete it?

:grimacing: Guilty as charged - running shoes! Yup, watts chucked away in favor of comfort. My feet and knees are okay in step in / clipless pedals for about 4-6 hours, after which they protest.
It was a conscious decision as I had planned to chug along slowly till I did 8848 (plus a few for safety). Cheers!

Respect! You soloed it! That makes it so much harder. Appropriate ‘T’ shirt, that’s what I felt like during the latter half of the ride. Cheers!

Thank you! Upper slopes of road that goes up to Lavasa (near Pune, Maharashtra, India). I have to say that the ladies in these parts are tougher than the men, several of them have done the 10,000m. Cheers!

I know for my suburban Everesting I popped a 32 on the back, and didn’t touch it for the first 4,000m.

… then after that I don’t think I came out of it! :sweat_smile:
