Bike setup for the TransAtlantic Way Race around Ireland

I’m heading to Ireland next week to take part in the TransAtlantic Way race, which starts in Dublin on June 7th, 2018 and then follows the west/Atlantic coast for a total distance of about 2,300 km. I’m looking forward to ocean views, small lanes, lots of short, sharp climbs, maybe some wind and rain, and some pretty long daylight hours.

I know several of the other people in the race, so I’m looking forward to catching up with some old friends and making lots of new ones. You can follow mine and everyone else’s progress on the TrackLeaders page, or their will be a new site ready for the race called DotWatcher that should be a lot more user friendly and integrated.

The Bike

Customized Specialized Diverge Comp SmartWeld 2015

I’m using a different bike than the two that I used for the TransContinental Race in 2014-16, so here is a brief overview. As always, I’ve modified and customized most of the components and accessories to make this a very unique and personalized machine. Click on any of the images to see a full-size version.

Frame & fork: Specialized Diverge 2015. It’s an aluminum frame with a carbon fork. I’m fortunate to also have a more recent carbon Diverge with the FutureShock suspension in the front fork, but that has a creak in the bottom bracket that I can’t get rid of even after changing many parts. The older, aluminum Diverge is as comfortable when using the RedShift ShockStop stem (see below) and has a couple of other very minor advantages, so I’ve decided to use it for the race.

Drivetrain

42-26 chainrings x 11-32 cassette. Ultegra Di2 derailleurs.

Gear ratios: 42-26 TA Specialites chainrings on a Shimano 105 triple crank. Shimano 11-32 11-speed Ultegra cassette. I have a chainring guard to keep my legs clean, prevent chain derailment and increase safety (I already have a scar from a chainring that took a chunk out of the back of my ankle).

Derailleurs: Ultegra Di2. Flawless and effortless shifting even with non-standard gearing combinations.

Gear controls: Dura Ace gear levers with buttons to control the Garmin Edge computer (using a wireless transmitter). Extra controls: bar-top (“climbing”) shifter and aerobar shifter for the rear derailleur. MTB junction box with gear and battery display. Two internal batteries, both inside the seatpost, the wire from either can be plugged into the system. Spare parts: wire and junction box.

Other Components

Braking: Shimano CX77 mechanical disc brakes, 160mm rotors. I prefer mechanical disk brakes because when they are setup well with good cable housing, they work almost as well as hydraulic brakes, are far easier to adjust and repair, and make it possible to have an additional bar-top mounted brake lever. Spare parts: Two pairs of pads.

RedShift Dual Position seatpost

Tires: Continental 4000SII Reflex. Nominally 25mm front and 28mm rear, but they measure 27mm and 31mm, respectively. Standard-weight inner tubes (I’ve tried tubeless tires, but found that punctures were still possible and they were a lot more hassle to live with). Spare parts: 3 tubes and a 25mm tire.

Saddle & seatpost: The Fizik Aliante saddle is an older-generation version that works great for me. The RedShift Dual-Position seatpost allows the saddle to be moved forwards by 5 cm while riding to give a more open hip angle when using the aerobars (see my full review). The saddle is in the forwards/aerobar riding position in the photo on the right and in the standard position in the full bike photo above.

RedShift ShockStop stem

Stem, handlebars & bar-tape: The RedShift ShockStop stem is excellent at absorbing shocks and giving a smooth ride (see my full review). The Ritchey EvoCurve WCS alloy handlebar has a wide 31.8 mm clamping zone for aerobars and accessories plus a flattened top section for improved comfort. Comfort is also ensured by the Lizard Skins DSP 3.2mm bar tape.

Aerobars: 3T Flip Clip On, with the Comfort model of the elbow pads and custom mounts to move the pads further behind the bars. Being able to move the pads out of the way to access the bar tops makes a massive difference for me.

Topeak rack-top bag, rear lights and rear PDW fender

Accessories

Mudguards/Fenders: Portland Design Works Full Metal Fenders, which are far more solid than any plastic models and are still reasonably light. Staying dry and clean is a massive benefit for comfort.

Rear bags: The rack-top bag is a Topeak MTX Trunkbag DX with the Topeak mount replaced by a RackTime mount. I prefer this to a saddle/seatpost mount bag because the rack-top bag clicks on and off the rack in a second, is totally stable, everything inside is easy to access and organize, and it allows me to put a drybag containing my sleeping bag behind the seatpost. The drybag is mounted using a Topeak QR CageMount that makes it easy to remove.

24: This was my race number for three editions of the TransContinental Race (2014-16). I’ve left it on the bag because it brings back good memories.

MooseTreks frame bag

Water bottles: Two 1000 ml Zefal Magnum bottles behind the saddle using a Topeak Tri-Backup Elite mount and Arundel Mandible cages. One 750 ml Elite SuperCorsa bottle under downtube with mud cover.

Frame bag: MooseTreks frame bag that I found on Amazon and is a perfect size for my frame after modifying some of the straps.

Topeak Toploader top tube bag

Top tube bag: Topeak Toploader. Large, inexpensive, and the new version has a far better zipper than the previous generation of the bag, which had been it’s only weak point.

Other bags: I dug through my box of saddle bags to find something that would fit under my aerobars and found an old Trek model that fits well and carries some of my rain clothes (see photo below). I also added a strip of fluorescent material because the race rules require to have something and I dislike wearing such colors.

Lights & Electronics

Front lights and bag.

Primary lights: SON dynamo hub with B&M Luxos U headlight. Rear dynamo light integrated into the rear rack (Racktime Shine Evo Light). I use Di2 wires and junction boxes, with re-soldered connectors because I find the standard dynamo wiring to be too primitive and the connectors very fragile.

Backup headlight: I have an Exposure Sirius front light that I can mount on the aerobars or on a helmet mount to give more light on any fast, twisty sections and use in case of dynamo failure.

Flashing lights: Two Moon Nebula front lights and two Moon Nebula rear lights. These are very bright and have good battery life. I normally only use one at a time and keep the second as a reserve. I also have a Lezno Zecto Pro front/rear reserve light (I’ve done races in which 3 rear lights have failed before reaching the finish).

Mission control.

Safety equipment: Multiple reflective stickers. Flourescent patches sewn to front and rear bags. Pedals with integrated reflectors. Tires with reflective sidewalls. Bell (mostly used to warn pedestrians on shared-use paths). Rear-view mirror (can be useful in specific road and traffic conditions, but I don’t use it that much).

Navigation: The Garmin Edge 1030 has the best screen and excellent battery life, especially with the external battery. Due to the external battery, I had to create a special mounting position. My backup navigation is a Garmin Edge 800 in my bag and an iPhone SE on a QuadLock mount (using the maps.me app). There’s also a StemCaptain clock mounted in the top of the steerer.

Weight: Total weight is about 20 kg without food or water. Typical weights for bikepacking setups are around 15-18 kg and some people have only around 12kg. I’m at the top of the range and I could push it to be a couple of kilograms lighter, but I prefer to be prepared and comfortable in most conditions and situations rather than being more lightweight.

Expectations

This is my first bikepacking race since the 2016 TCR, so I’m really eager to get going. I’ll be pleased if I can average at least 300 km per day, but that may be tough with the challenging terrain, so I’ll be adjusting my goals as I go. I’ll try to upload my rides to Strava, make some posts on my Facebook page, and again you can follow me via the satellite Tracker page.

  1. Good luck on your ride!

    One note in regard of the dynamo connectors: I was unhappy how fiddly the connection to a SON dynamo was (especially in comparison to my Shutter Precision dynamo) and went to my LBS. They had just gotten a new connector from Schmidt that probably will solve the fiddly part and be better suited for some roadside tire change.

    1. Thanks for the advice. I also managed to find some connectors that were just the right size for the SON this time – not too tight or too loose, so I don’t mind those (on a previous bike, my SON connectors were far too tight). It’s more the fiddly and fragile ones that connect to the lights that I dislike most and which I’ve replaced by having a friend solder Di2 wires directly onto the headlight’s internal circuit board, then having Di2 junction boxes taped to the outside of the headlight.

  2. That’s a very busy looking bike! Is there room for you in there? 😉
    Didn’t mention the whheel set up.

    Good Luck, weather in the U.K. has been very hot.

    1. Thanks. The front hub is a SON, 15mm thru-axle, 28-hole. The spokes are DT Swiss Aerolite. The front rim is a carbon model from BDop Cycling, who keep the cost reasonable by selling direct from Asia. The rear wheel that I have with the same rim doesn’t fit on this bike because of the axle. I therefore used the Axis (Specialized) rim that came with the bike because it has 28 holes and offset drilling and re-built it with a Shimano CX75 QR hub and DT Aerolite spokes again.
