Deemount Magene/Garmin Radar rear light saddle mount - https://www.aliexpress.com/item/1005005989328996.html - really nice bit of kit for mounting a radar light, holds well and clamps nicely on to round and oval saddle rails
Fire Spider (The One) Integrated Bar & Stem - https://www.aliexpress.com/item/1005004380752458.html - I'm a huge fan of these bars, they are sleek, stiff, and comfortable. Plus the wedge clamp makes for a much less concerning install (vs clamping carbon). I've had a pair in matte, and in gloss and the gloss is nice but the top cap is not painted and the gloss paint tends to chip a little around the top cap area.
UNO Stem (MTB/Gravel version) - https://www.aliexpress.com/item/1005004638826623.html - bit more robust than the lightweight offerings, low stack (30mm) too. Good if you're running a shorter stem and want something more substantial.
