Bikes of GranGuanche Audax Gravel 2024

29 March, 2024

This 700km route goes by fast gravel roads and secondary paved roads while avoiding rocky singletrack or sandy sections. It's open to any kind of bike, but the organizers recommend gravel bikes with low gearing and a minimum of 40mm tires.

You will see from the submissions that the balance between speed, weight and comfort has resulted in a range of bikes with tyre choice being of particular interest and importance. Also considering the lack of natural water sources on the islands, the riders will have to rely on establishments and have the capacity to carry resources over distance.

Remember: this is not a race, it's an audax. But that doesn't stop some riders setting out to test their mettle!

Follow along with the tracking here.

James Brodhurst

Name: James Brodhurst

Age: 53

Cap number: 052

Location: Valladolid, Spain

Bike: Built around a 2022 J.Guillem Atalaya Ti frame. Drivetrain is SRAM Force/Eagle AXS mullet with 10-52t cassette and a 36t chainring - I usually run a 40t or 38t but with some serious gradients on the route I’m going for extra gearing.

The wheels are the excellent 650b Stayer Gravel Adventure wheels with a Son Delux dynamo front and a Hope RS4 rear hub. Running them low pressure tubeless with Vittoria Airliners and Schwalbe 2.1” Thunder Burt tyres.

Extra-comfort dept.: the Profile Design Sonic aerobars, a Redshift Shockstop stem holding the Lauf Smoothie handlebar and a Brooks C17 Carved saddle.

Key items of kit: Bags are a mix of Miss Grape (bar pouches), Restrap and Apidura bags above and below the top tube, the Wayward Riders Louise harness with a dry bag out back and a simple dry bag strapped to the ‘bars with my sleep kit. No sleeping bag, just a SOL Escape bivvy, Sea to Summit Ultralight mat and my spare clothes to keep me warm. If it rains, will be looking to sleep under some kind of shelter!

Electrics will be charged by the dynamo, with K-Lite front and right lights, their USB charger and a pass-through battery to keep phone and Wahoo charged.

Other kit – Apidura hydration vest (for food and 2l of water) plus another 2l in bottles.

Key items of kit: Apidura seatbag and frame bag, with 1,5L bladder inside. For extra water carrying, I'm rocking two Wolftooth cargo cages on the fork. Between the aerobars, I'm putting a Fairweather stem bag to house as much candy as I can carry. The 7R top tube bag I'm filling with electronics (DJI Osmo Action 3, point and shoot film camera, power bank, etc.). For lights I chose to go for Fenix BC26R with an extra battery on the bike and Exposure Joystick on my helmet. Sleep system will be a sleeping bag and a sleeping pad. This is my first ultra, so I'm trying to enjoy it and maybe even sleep on actual beds for a night or two.

Johannes Santen

Name: Johannes Santen

Age: 34

Cap number: 55

Location: California, USA

Bike: I'll be riding my trusty Rodeo Labs Flaanimal 4.1 with Rodeo Labs rims, a Rodeo front hub, a White Industries rear hub, and 650b x 48 Rene Herse knobby tires. The drive train is 1x with a 38T chainring, a 10-52T cassette, and AXS rear derailleur. I recently upgraded to wireless shifting and I love it! Hope my batteries don't run out lol. JK I brought a charger. There is also a power meter to tell me how hard I'm working while carrying all my stuff up Teide at 6 kph. Other than that, I have Curve Walmer carbon drop bars, which are very comfortable, and to top it off, Profile Design Sonic Ergo 45AR aero bars. I've never used aero bars in a race before, but I think they'll be a nice addition of comfort. Plus they will save me at least 10 minutes on Fuerteventura ;). Slowing me down, I have Hope RX4+ brakes, which I'm sure will reduce hand fatigue during the long and/or chunky descents on the course. Finally, for lighting, I have Exposure Race, Joystick, and TraceR lights, plus an extra battery for the Race front light, which can last for up to 72 hours (on low).

Key items of kit: Even though I was trying to keep things relatively minimal and light-weight, I still ended up with a lot of stuff somehow. I guess I like options, especially not having to rely on hotels. So I brought a custom Timmermade false bottom sleeping bag, a Mountain Laurel Designs Ultralight Bivy, and a Thermarest Neoair sleeping pad, all to keep out the cold in the mountains. I left the tarp shelter at home, so if it looks like it's going to rain, I'll have to find decent roof or a hotel. Bags are Apidura (half frame bag and seat bag), Rockgeist (handlebar harness), and Tailfin (top tube bag). I have a lot of room for food. And I'll also be wearing my 2L USWE hydration vest for even more snack storage and water. Plus, to keep my teeth clean, I brought a spork with a toothbrush attachment!!

Maya Wolf

Name: Maya Wolf

Age: 34

Cap number: 68

Location: Berkeley, CA, USA

Bike: I am riding my xs Pivot Vault with a SRAM Force group set, 36t chainring (I usually ride a 38t chainring but this route seemed to call for something even smaller for maximum smiles), 10-52t cassette, and 45x650b Pirelli Cinturado tires (M in front and H in rear). For water, I’ll have a 710ml bottle in the cage, 1.5L bladder in my Oveja Negra 1/2 frame bag, and another 620ml bottle in a stem bag.

Key items of kit: I have Oveja Negra saddle and top tube bags, and Revelate handlebar and stem bags. For lighting I’ll have an Exposure front light, Outbound Lighting helmet light, and Bontrager Flare rear light. After much deliberation, I’m also sporting Profile Designs aerobars.

I am bringing my Therm-a-Rest XTherm mattress, a Sol Emergency bivvy, and a Therm-a-Rest pillow for sleepy times. Other major items of gear include a) various pills and potions to avoid seasickness on the ferries and b) various creams and such to keep my rear end happy (Squirt chammy cream, soap, zinc oxide cream for quick overnight healing, and Voltarin and lidocaine to treat a chronic nerve injury down there). I’ll basically be a moving apothecary, wish me luck!

Teddie Vidolova

Name: Teddie Vidolova

Age: 33

Cap number: 83

Location: Oakland, CA, USA

Bike: I will be riding my dream Rodeo Labs Trail Donkey 4.0. You can find more glamour shots of it here.

I specially selected the Allygn Rack, matching Gramm Diamond Bag, Lauf Smoothie Bars, Ergon CF Allroad Pro Carbon seatpost, Supernova M99 DY Pro dynamo, and the e*thirteen 9 to 52 Helix cassette.

Modifications and acquisitions I made specifically in preparation for the Granguanche Gravel Audax are the custom half frame bag by Wit Slingers (thank you for the super excellent service Tijmen), the Tailfin Top Tube Bag, a 36-tooth chainring, cushy Silca Nastro Cusino 3.75 bar tape, and 48mm (measure more like 47mm on my rims) Oracle Ridge Extralight Rene Herse tires because I like to gamble and am a Jan Heine devotee: I believe he would run extra lights on this course. I got a bottle cage adapter so that I can still fit a 1L bottle in one of my cages. Total water capacity ~2.5L.

A lot of the other pieces of gear were tried and proven by last years Trans Balkan Race.

Key items of kit: I will be bringing a minimal sleep kit: a Therm-a-Rest NeoAir UberLite sleeping pad, Polycro ground sheet, SOL Escape Lite Bivvy, and Sea to Summit Aeros Down Pillow. No sleeping bag, so really hoping to credit card tour as much as possible.

I will have my Rapha Down Jacket, Rapha Rain Jacket, and Ridge Merino 3/4 leggings for inclement weather on Teide. Rapha Brevet vest for all of the night riding.

To prepare for almost certain sea sickness on the ferries, I will be trying out the EmeTerm Anti-Nausea Wristband i.e. electroshock therapy. Also high concentrations of ginger.

To hopefully avoid a yeast infection this time, I am taking prophylactic boric acid and probiotic suppositories in the days before the race.
