As i said in my 1st post just send me £100 , i think its a valid investment
Depends on what you want from a computer, you can get one for £10 that will be adequate or get a garmin 200 if you want to get techy and track yiour rides etc but if you have a smartphone then their are plenty of apps that do the same.
Your talking to a guy who buys most of his jerseys via
ebay looking for the "gave up cycling " sales
Imho make sure you have the pump, multi tool, tyre levers, puncture repair kit , inner tubes ,saddle bag and shoes.
Track Pump ! how did i forget !
makes life a lot easier by being able to pump up your tyres quickly at home and use a decent mini pump on the road .
