Trek Checkpoint ALR fixed/singlespeed (UK edition)

I decided to go with fixed over singlespeed - everything came together very quickly and in time for the 1st day of the railway strike, which was surprising as I'm prone to faffing around a lot.

So I got rid of my centrelock wheels, sold them to a guy locally on eBay who had had his wheels nicked. I picked up a WTB wheelset from @BillyPilgrim - unfortunately, I thought the tyres were too wide for the frame, so I had to remove them and do some musical chairs with the tyres on my girlfriend's gravel bike which are 40c WTB Nanos (vs the 45c WTB Riddlers).

WTB rims and tyres set up tubeless seem to be an unbelievably tight fit. I had to stand on the tyre and try to rip them off by pulling on the wheel. In hindsight, I think I could have made the Riddlers fit by moving the dropout adjustment back.

I removed the 50 ring from my 50/34 Tiagra crankset and put the 34 ring on the outside. The chainline was a bit off, so I installed some chainring spacers. The most I could fit was 2mm, idealy 5mm or more would make for a better chainline but there's no space. This is combined with a 17T sprocket in the back. The gearing is a little low for road, comfortably sitting around 20-25kph, but for offroad it's perfect for me.

I found some cheap Tektro levers and Promax Decode R mechanical brake callipers. I don't know much about disc brakes and the Decode callipers get mixed reviews, but they slow the bike sufficiently and they were cheap - no complaints here.

Everything else, saddle, seatpost, handlebars were left over, nothing special.
Specialized Pizza rack fits nicely on the front and I've ordered a bag for it from @user71349 and that should complete the Thames path commute crusher.
