Le Update: I reckoned that making puppy eyes at Hannah and Chris wouldn't work, so I suggested giving them money at their very reasonable rates, which worked a treat.
I had to go with flat bars, which look foooogly compared to Kappers' old bullhorns, but they're better for hauling up on during the extra 8-900ft of climbing I have since moving to the Templar's digs, and that's going to matter more than the aero.
The B&M Luxos B throws out 70lux in a beam that's got the oncomer-friendly cut-off, but floods the road ahead and to the sides. I initially thought I'd wasted the ~£12 that takes you from Cyo to Luxos, but I find it oddly comforting to see the verges of unlit roads so clearly.
I don't rate the standlight as highly as the IQ Fly that I did have, but that might just be because that was a humble 20lux, so it could be exactly as bright and I'm just confused by having over three times the drop in brightness.
As a very minor annoyance it's really flickery when pushing the bike along. I'll miss the automagic light sensor mode of the Fly.
Hydraulic discs, the centrepiece of the enterprise, are your classic strong, silent types. They start off underwhelming as the pads bed in, then quietly get on with the job of bringing you to a halt exactly where you want to without thinking about it.
Does anyone want a S-A dynodrum hub and/or 36 spokes+nipples of the length to lace from said hub to a 700c rim? One abusive owner, but no apparent damage.
