Hi all!

Is a 1 inch headset able to fit other headtube sizes or are there even headset sizes at all?

Is a non-threaded head tube able to be fitted with a threaded headset?

Are headsets easy to assemble,easy enuogh for a small boy like me to fix?...

How do you know if an RD is compatible with a frame?

Thanks guys if you have any answers to my questions...
Still got a lot more...But this are the ones i really need to know... Very Happy

Hey I'm afraid I don't know much about headsets to help. But I dun think threaded and non-threaded can mix. Anyway to change headsets you might need special tools to knock out and install the headset bearings.

As for the RD, it should not matter what frame you are using. RD should be compatible with any frame, but you will need to check if its compatible with the shifter (SRAM or Shimano) or cassette (Short or Long cage RD). Just take note that the number of speeds is determined by the shifter not RD, so shifting should be fine as long as Shifter speeds = Number of sprockets on cassette

Hope it helps! I'm sure other people will chip in with more info.

Regards,
Steve

Threaded headset easy to do one. No need cup press. Use a pipe to knock the old ones out and use the pipe to knock new ones in place. GREASE IS NEEDED.

I'll take a stab at this - it's possible to use MTB crank and roadie cassette if you can get a decent chainline. It depends on your bike frame. A triple chainring MTB crank combined with a 10 speed roadie cassette may spell trouble for frames with shorter chainstays.

As for MTB derailleur with roadie cassette, should be no problem. As steve said above, shifter and cassette must match. The derailleur just does what the shifter tells it to do Smile Bear in mind that the opp ie. mtb cassette and roadie RD will probably NOT work as the RD will not have enough throw to cover the range of the mtb cassette.

Cheers!

A 10 speed cassette is wider than a 7 speed cassette. So if you use a 10 spd with triple mtb cranks your chain would make a sharper angle when you're using the extreme ends of the cassette ie. largest and smallest cog. This problem is made worse when the chainstay length of the frame is short ie. that means that the distance from the cassette to the crank is short and it's difficult to achieve a good chainline.
