Bikes of Seven Serpents 2024

11 May, 2024

A set-route race between seven checkpoints from Slovenia through Croatia and its islands finishing in Trieste, Italy along a mix of gravel and secondary roads. Last year's event was hampered by pre-event rain and mud, but the forecast this year looks much more pleasant. On the cards are 850km with 16,000m of climbing, a handful of which will be done on foot.

The 98 solo riders and 13 pairs tackle this gravel race starting at 7am on Sunday the 12th May, you can follow along with veteran Marcus Nicolson's commentary here.

It is from Stuttgart based bike bag manufacturer @fo.goods and has a custom mount for my light, the knog blinder 900. The setup is held in place with the sixtysix - a steel pipe that is mounted to the handlebar. In this bag will be the sleeping bag, pillow, toothbrush etc.

Additionally my saddle bag from Ortlieb contains all clothing and my isolation mat. I have two jackets with me, one shell and one down jacket, a few spare tools, batteries, cables. Max and I split the tools and emergency equipment that we carry.

I have the Canyon aero frame pack which contains additional stuff like a pump and the powerbanks and my top tube bag from Canyon which contains snacks and one powerbank which is charging my Wahoo or my light.

Looking forward to go on to the journey with my buddy and roommate Max.

Ride hard, drink soft!

Max Zorn

Age: 29

Cap number: 111

Location: Stuttgart, Germany

Bike: I'm riding a Canyon Grail - the one with the double decker cockpit. I upgraded the wheelset to the 40mm Allroad BASIC Gravel wheels by LEEZE, equipped with tubeless Schwalbe G-ONE RS 45-622 (that measure 42mm irl and barely fit in the frame). Groupset is a mix of 2x GRX 800 in the rear and 600 in the front. I did change the cassette to a 11-40 which works surprisingly well and, together with the 46/30T crankset, will hopefully provide enough gearing for the steeper climbs and the tired legs. The chain is hot waxed, which I hope will last a while before I have to apply lube during the race.

Key items of kit: The bike's cockpit and missing attachement points pose a bit of a challenge for finding the right bags. I chose to not use any handlebar bag, as I always find the positioning and handling awkward with the double decker cockpit. Instead, I went with the Tailfin AeroPack Alloy, where I'll carry my sleeping setup (Sea-to-Summit Spark II sleeping bag, a bivy, and a lightweight pad), as well as spare clothes. I also use an Ortlieb frame bag and a Tailfin top tube bag for what I need during the day (snacks, battery packs, armlings, etc.) and some larger items (pump, spokes, straps...). My tools are stored in a locally made bag by fO.goods. For lighting, I use Knog Blinder front and rear lights, and a Black Diamond headlamp. I 3D-printed an attachment for my front light, so it mounts directly to the Wahoo. Apart from my water bottles, I'll be using a USWE hydration vest with a 2L bladder, which should bring me through the remote areas. The lucky item will prolly be a bear bell that a fellow serpent gave me for my birthday.

Bike: Juliana Quincy - 'Ol' Faithful'. Arkane 650b with SON Dynamo. Switching up this year, running a Teravail Rutland in the front for extra grip and a slicker Teravail Cannonball in the back.

Oscar Huckle

Age: 26

Cap number: 40

Location: Bristol, UK

Bike: This is my custom Niner RLT 9 RDO with Campagnolo Ekar and Fulcrum Rapid Red 5 wheels. I've used this frameset for bikepacking and epic rides in the past and I find it very comfortable and versatile with its 50mm tyre clearance. Although I typically run a Campagnolo Shamal wheel on this bike, I thought I'd go with my Fulcrum winter wheels to stand up to the route's abuse and they're shod with new Pirelli Cinturato Gravel RCX tyres. I love the RC tyres and hope the RC X's will be better suited to the monster gravel on the route. Rounding off the build is an Easton EC70 AX flared carbon handlebar, a Roval Terra seatpost and my trusty Fabric Scoop saddle.

Key items of kit: I'm predominantly running Apidura Expedition bags because I've really got on with these in the past. However, I've switched to an Apidura Backcountry top tube bag for the extra storage and I'm using the Niner frame bag as it integrates with the frame. I debated using fork bags too but after seeing the minimalist set-up's, I've decided to go a bit lighter and wear a hydration vest instead. As for sleep, I'm carrying a Sea to Summit Spark Ultralight sleeping bag, a Big Agnes Rapide SL mat and an Alpkit Hunka XL bivvy, just in case.
