Another vote for Aldi tops – I ended up buying one of the skinny ‘pro’ jackets because the standard softshell is just so warm. It was so cold one night that my bite valve froze but the cheapo aldi top and a Helly Hansen t-shirt thing kept me plenty warm.
Just wish they’d make some 3/4 waterproof shorts.
FSA Orbit XL II headset – paid ~£20 and it’s ace. Has outlasted 3 XT bottom brackets and numerous Hope bearings. Great bit of kit.
On One / SSC CNC stem – light, cheapish and pretty.
Genuine Shimano finned pads – not cheap to buy but last ages and are brilliant so great vfm.
