Will this work with 130 OLD spacing?

Hi there,

You should be able to use this without an issue, however as we have never done this we cannot say for certain im afraid.

Will this be compatable with Shimano Rear Derailleur RD TX35 6/7 Speed Tourney

As long as you use the SGS model of that derailleur, yes this will be fine.

Hi I have two bikes one 6 gears 14x28 teeth
one with 7 gears 14x28 teeth, can i fit 14x34 teeth on to both bikes

This will all depend on your rear derailleur, if this can cope once adjusted wit as large a sprocket as 34T then you'll be fine to fit these.

Width Of Shimano E-Mf-T31 7Speed Freewheel 14-34T. Thanks

Max I can fit is 32/3mm

Unfortunately I think this freewheel won't be suitable I'm afraid as it measures 34/5mm wide.
