I bought the Surly in London with original components, of which only the stem, brake, headset and bottom bracket remained. I slowly upgraded the other parts:
– Halo Aerorage wheels
– Wing riser bar
– BLB crankset 46t and 16t sprocket
– Charge seatpost
– Shimano clipless pedals
– Bike Positive/Selle Bassano saddle which is OK for city use but unsuitable for longer rides.
