Damn, I really did NOT update this thread with how this project got on.
Well, 2.5 years later I've almost done 40,000km on this frameset and just won the biggest alleycat ever held in London on it. Here's a little breakdown of the set-up for that.
The race-winning set-up. This is what I used to nail 1st place in @thegreatalleycatoflondon last weekend.
56/18 gearing. Rear cog attached to the disc rotor side of a road wheelset. A cog with drillings for a 6-bolt attachment - however the hubs are Centrelock. So had to use an adapter and that seemingly had a tendency to loosen and was impossible to centre. I just used a load of threadlock and elbow grease and it appears to have survived over 100km of hard riding. Brand new Izumi chain installed 2 days before the race. Fully degreased and relubed for best efficiency.
Frame bag by @mackworkshop housed 2 spare tubes, required tools, a bottle of Coke (deployed at end of 2nd manifest) and some sweets. A bottle with electrolytes and sugar. Another with Red Bull. I'm always bad at hydrating on the bike but knew I couldn't mess around with this effort. The bag and cages were also used on my ride around Australia so they had a heap of residual adventure energy to them which helped fuel the smashfest in a metaphysical dimension.
Ergo grips paid off nicely for stopping hands getting sore. They also make it easier to hold a phone whilst riding. Which is crucial when navigating on the fly and for selecting the perfect Spotify soundtrack.
I also started the race with a rear puncture. I was running tubeless and it would occasionally spurt out some juice towards @the_sprinting_sanchez and @robroskoo who were chasing me. Like some sort of flare or octopus ink defense method. However, the tyre maintained 60-70PSI the whole race which is what I wanted anyway so it was all good.
Loved the set-up. Love this frameset. Running 25mm tyres on a gravel bike did make pedalstrike a hazard - and did cause me to have one minor crash. Derp!
Fun fact: The handlebars are 66.6cm wide and my route ended up being 66.6 miles.
