I had all the spare bits in my shop and the bike built up very nicely over the course of a few hours.
My old winter bike (Kuwahara Shasta) got retired from winter duty so I could use it for everything else but the harshest of winter riding where an IGH and studded tyres really make a difference... has been so nice that I have taken out the Shasta if I know I am going to be riding on clear roads and there is no threat of snow or freezing rain.
The Shasta donated the winter wheel set that is on the Norco and got it's 18 speed drive train restored and is still very capable of handling some pretty nasty conditions (sans studs) as it is well fendered.
Rode that yesterday and was thankful for it's identical fenders as they kept all that freezing cold water and road crud off of me and after 20 km I barely had a speck of dirt on my boots or clothes.
It feels like spring where you never know if you are going to need studs and where the weather can change on a dime.
