What I am looking to do is to change the crankset to a double. The whole reason behind this is chain rub. It's one of the most annoying/embarrassing noises to put up with when riding, which I thought I got rid of when I moved from kids mountain bikes to a road bike.
1. Most shifters have a trim function to fix chain rub on front derailleurs.
2. Chain rub on the big ring is much more likely with a 50-34 compact double because of the larger difference between chain rings and chain angle greater due to the more inboard location of the 34 ring
Do I need to change the front dérailleur?
Perhaps.
Has anyone any experience with this? Is it viable and useable, or is there anything I could change to get the triple to work better without the chain rub? (Obviously the gears have been set up as best as I can do them)
Use the shifter trim function or switch to Shimano if Microsoft lacks it.
