Hi everyone, beginner here. Excuse my English I’m French. I was wondering why everyone uses clips-in for the bike? I removed them on my bike since I’m not really comfortable with them and put good straps pedal instead. I was thinking it’s the same since I can also pull and push with these and I figured I’d save time on my transition between bike and run since I’ll have no change to do with the shoes. Does it really have an impact for my first tri in 4 months (sprint 750m swim, 20km bike and 5km run) and if so how?
