Hi guys and girls, so Im new to the bike scene and just finished my custom Pinarello-Dogma build... Im stuck on what onboard computer everyone is using and so forth. I have done lots of research and I think it's best if I speak with real life cyclist and there gear and experience. So the question is, do I buy a high end computer to do everything or do I just use my phone with an app? What works for you and what are you using? Thank you in advance guys and girls and happy cycling.
