Here's an update on the NFE build:
Swiss Stop 15s brake pads
After 4 long rides (160+ km) we swapped out the resin OEM pads of the Spyres for a new pair of the Swiss Stop 15s (sintered/metallic) pads recommended by other TRP owners and it's been a revelation.
The new pads are quiet and work just as well after the 360 km weekend ride as they did before. The OEM pads that came with the calipers would have needed adjusting after half that distance due to rapid wear, plus they were much more noisy. I actually threw the old pads into the bin even though they still had some life left because I knew I would never put them back on the bike again.
If you're using TRP Spyre or Spyre SLC cable-operated disc brakes, the Swiss Stop pads are highly recommended!
Secula Plus dynamo rear light
The day before the brevet I wired up the rear light using the supplied cable and Shintaro crimped and soldered the connectors at the other end of the cable to hook it up to the dynamo hub.
The Secula Plus is mounted on the rear mudguard (fender). From there I ran the cable along the drive side mudguard stay, then ran it along the rear derailleur cable up the seat stay and on the top tube. I used zip ties and electrical tape to keep the two cables together. Near the handle bar I dropped the power cable down to the front rack to which I also zip tied it before hooking the power cable up to the head light.
I ran the cable on the drive side of the rear wheel to keep it out of harm's way from the brake rotor when taking out or reinstalling the wheel (e.g. during a flat repair). Running the power cable right next to the derailleur cable makes it unobtrusive and takes advantage of the mounting points on the frame that exist for zip-tying the shifter and brake cables to the frame.
The Secula Plus performed well during the two hour evening ride to the Machida start point and the 8 hour night ride from Machida to Numazu. Its capacitor powered stand light is very effective. I can stop at a conbini, use the toilet, do my shopping and refill my water bottles and when I come out into the parking lot again, the rear light is still illuminated. So it's got plenty of power for when you need to stop by the road side to put on a jacket or to check a map and want the car and truck drivers to still see you at night.
