Bike shops are asking 100+£ for a bike assemble and it might be justified but its too much for my budget and I want to DIY it.
Is that risky to do by watching youtube videos and borrowing tools from friends?
I want to install an english threaded bottom branket with a squared tappered crankset, disc brakes (mechanical), headset (threadless including cutting stem).
Half a year ago I built my bike with friend who had side hustle repairing bikes.
He had nearly all tools and know how. I will advise you to find someone who will help you with that. It is not hard but for the first time it is better to have someone to show you.
I did it because I have do it all/ bikepacking bike so I want to know how to not get stuck on the side of the road 500km away from home with heavy bike (with bags). And I know how to repair it/ maintain it to get to work each day.
Now I have racked up about 4000km on it and few mishaps/breakages later I wouldn’t do it any other way because I was able to fix it and get on the road again in few minutes every time.
