When a triathlon community speaks loudly enough, manufacturers listen — and the Spocket Side-by-Side BTS is proof. Born from forum feedback on Slowtwitch, this CNC-machined carbon plate represents what happens when athlete-driven design meets precision engineering.
What Is the Spocket Side-by-Side BTS?
The Spocket Side-by-Side BTS is a dual-bottle mounting system built specifically for triathletes who demand reliable rear hydration on race day. Machined from carbon fiber and secured with titanium hardware, the plate mounts to the tail of Wove V8 or M8 saddles and holds two bottles side by side — exactly where you need them on a long-distance triathlon bike leg.
Unlike generic aftermarket mounts, this system was shaped by real-world input from the Slowtwitch forum community. Athletes reported vibration-related bottle ejections, marginal retention under load, and compatibility headaches. Spocket responded with a purpose-built solution rather than a compromise.
Community-driven design doesn't just improve products — it creates gear that athletes already trust before they unbox it.
Engineering Details Worth Knowing
The plate is CNC-machined, meaning each unit is cut to tight tolerances rather than molded, which reduces flex and micro-movement at speed. Bolted titanium hardware keeps overall weight low while providing the clamping force needed to resist road chatter and cobblestone-style vibration. The result is a mount that stays quiet and stays put through the entire ride.
Compatibility is intentionally narrow: the Side-by-Side BTS fits the Wove V8 (both v1 and v2) and the Wove M8 saddle. If you run either of those saddles, fitment is straightforward. If you don't, this particular system won't transfer over — a fair trade-off for the precision it delivers on supported platforms.
What Comes in the Box
The package includes the carbon plate and titanium mounting screws. Bottle cages are sold separately, so you bring your own preferred cages to the setup. This keeps the system flexible — you can run whatever cage geometry works best for your bottles and access style without being locked into a bundled option.
The Slowtwitch Forum Effect
The triathlon community has long treated the Slowtwitch forum as an informal product testing lab. Athletes document failures, suggest improvements, and occasionally spark direct conversations with manufacturers. The Side-by-Side BTS stands as a case study in that pipeline working exactly as intended — a thread-level frustration turned into a production product available for purchase at the Slowtwitch Shop.
For triathletes shopping gear, community provenance matters. Products tested and debated by athletes who race the same courses you do carry a different kind of credibility than catalog specs alone. Read the full origin story at Slowtwitch.
