I have a shimano acera crankset (3x) that is 28-38-48 with a 8 speed rear derail. Now I was going to convert this bike into a SS but decided not to mess with it. Can I take off the middle chainring (38) and replace it with a 44 teeth chainring instead without any messing/adjusting with the front derail.? (I'll just be using the middle chainring)

  • Are the front chainrings bolted together or are they rivetted together? Its not going to stop you disassembling, but may cause problems on reassembly.

You'll have to 'mess' minimally with the FD in a way that you'll have to adjust the min/max screws to lock the FD in position and (better) remove the cable. Leave the derailleur in place as it will act as a chain-guide.


Yes, that is possible. Apart from adjustments to the front derailleur in @Carel's answer, you will have to purchase some shorter single chainring bolts as your double chainring bolts will be too long.
