With Mark Beaumont having successfully completed his round-the-world ride in 79 days to smash the Guinness World Record, we thought we’d take a look at the bike he used for the challenge.
These photos were taken before the challenge; we don’t yet have any of the bike after he’s ridden it for 79 days, but hopefully, we’ll get some soon and update this article. That aside, it’s an interesting look at the equipment choices Mark chose for the ultra distance challenge.
Mark Beaumont has long been supported by Dutch bike brand Koga - it was a Koga WorldTraveller that he used for his first round-the-world challenge in 2008 - and for this new challenge, he opted for the company’s Kimera Premium.
The bike Mark actually rode wasn’t quite stock, it had a very special custom 80 days paint job, a reminder of his target, with his signature along the top tube. It’s a carbon fibre endurance bike built around disc brakes with thru-axles. The frameset was built up with a Shimano Ultegra Di2 groupset with hydraulic disc brakes.
Shimano’s electronic groupset might seem an inappropriate choice for endurance cycling but it does offer numerous advantages. It’s extremely reliable and there are no cables to snap and fail, the battery last ages (and Mark was supported so no fears of a flat battery) and allows satellite shifters to be added to the extensions.
Time trial aero extensions are popular with endurance cyclists. They offer a more comfortable position for the long periods of pedalling as well as reducing the effort required by reducing overall drag. Mark used a Profile Designs regular handlebar with clip-on extensions with foam arm rest pads.
To ensure a comfortable position, Mark opted for quite a high setup, with plenty of spacers raising the stem and the extensions angled upwards. It’s not a position you’d want for a 10-mile time trial, but clearly ideal for 79 days. And to enable shifting without moving from the extensions, the use of a Shimano Di2 groupset allowed shift buttons to be added to the end of the extensions.
The Kimera offers wide tyre clearance, and Mark opted for 28mm wide Panaracer Race Evo 3 tyres. road.cc has tested these tyres and been impressed with their performance and durability. It doesn’t appear he went with a tubeless setup, and presumably, that’s down to the fact he had a support vehicle so changing a flat inner tube would be a cinch. He went through a set of tyres in about 3500-4000 miles.
Those tyres are fitted to Corima 47mm deep section carbon wheels, not the Shimano RX31 aluminium clinchers that come on the stock bike. Corima is a French wheel manufacturer that is relatively unknown compared to the likes of Shimano, Mavic, Enve and Zipp in this sector, but it does make some exceedingly lightweight wheels.
What really matters above all is saddle choice. Mark's choice of a Selle SMP PRO is an interesting one. The distinctive droopy nose saddle has a large central cutaway designed to reduce pressure on the perineum. The rear of the saddle is raised to provide seated support when pedalling and the nose is intended to provide a flat base when sitting.
Obviously, Mark didn’t need to laden his bike down with any bikepacking or pannier bags, adding just an Altura top tube bag for a handy place to store food for each day. A Garmin Edge 1000, two water bottle cages and Exposure front and rear lights complete the minimum build of this record-breaking bike.
What do you think of Mark's bike and equipment choices?

What model exposure lights?
Flare or blaze?
Diablo Upfront and TraceR out back. the lightest pairing for the output.
Forget the hardware, what about the bibs?
I expect they're a bit sweaty
Corima's as ever, rocking and doing what they do best.
How many chains, cassettes, and chainrings did he get through?
When I rode with him out of Anchorage he mentioned that they were changing chains around every week. Can't remember what he said about cassettes.
He also mentioned that he picked ultegra due to reliability over dura ace which I think he said he used on his africa trip.
The Selle SMP saddle I can agree with - definitely my choice for a ride like this.
I'm amazed it held up throughout the journey, though. While my Selle SMP Hell was pretty comfy for commuting and a 200 km audax, its top cover started cracking at the verge of the cutout area after about a year and 6000 km of use. The Pro model Beaumont used is probably better built as it's twice the price.
Bet Shimano weren't too chuffed with the additional exposure their Ultegra cranks got when one snapped.
It was actually a Stages power meter adapted Dura Ace crank that snapped.

I were right about that saddle though.
I suspect this might have been lost on younger readers
I smell a rat.
There's no way a Garmin Edge 1000 battery could last for the 16 hours a day he 'allegedly' spent riding!
My Edge Touring Plus wouldn't have gotten me as far as elevenses without locking up or turning itself off.
propably never heard of an additional external battery pack
What Mr Beaumont has done is truly a phenomenal achievement. As soon as his book/video of this trip is released a copy will be in my hands.
