Hi

I’ve been watching this thread for a while and considering (strongly) building an ATR bike, can you help me specify what might do the job? There seems to be a great community so wondering if you can help me out.

Budget: £3k or less (had a bit of a work surprise but happy with second hand parts if no reason to buy new etc)

Use:
20 mile RT commute on bad roads
Summer tow path with baby seat on rear pannier
Winter riding on tracks round local (big) park tracks
Winter training rides round box hill etc

Thinking of 40mm tyre, front and rear guards and rear rack.

So what parts would you suggest – groupset, gearing, hydraulic brakes, headset, wheels & tyres to fit the budget?
(Also i like loud colours so anything to bring a bit of fun wouldn’t go amiss.)

Rider: 95kg

Thanks!
