Vladimir,

I may be wrong, but I think that you have two options that you may not have considered:

Buy a new gypsy from Lofrans to match the 31mm pitch...I think that Lofrans makes 3 different 10mm gypsies. They are around $200 each.

Or buy US chain that has a 30mm pitch...it is available.

Or, buy thw chain that you are looking at with 31mm pitch. Try it. If you don't like the way it works in the gypsy, then buy a Lofrans 31mm pitch gypsy.

Either of those are viable options.

One other remark about new chain: Whenever you install new galvanized chain, it will not begin to run smoothly through the gypsy until it has passed through the gypsy about 10-15 times. The reason ia that there will be small chips of zinc breaking off the chain as it passes through the gypsy. This is my experience and others that I have talked with about new chain.

BTW, I am fairly certain that most Americans don't realize the difference in pitch that is available in 10mm (3/8") chain. Most just buy what us available and if it is off by 1 or 2mm it just skips a little in the gypsy.

Bill, thanks for your email and for good information.

That problem was discussed before, but I could not find the conclusion for this discusion.
I hope that someone already tried that. It is less expensive to buy US chain.

Vladamir,

Be careful, your gypsy is cut for a pitch of 30mm and the chain you are looking at has probably a pitch of 31mm. Pitch is the measurement of the inside of the length of a link.

American chain is made mainly to ISO G30 and G43 standards with longer links that may not fit European gypsies. I believe that Lofrans makes a gypsy for 10mm (3/8") that has a 31 pitch.

Hi Gary,

I want to buy 3/8 " G4 ACCO chain. I have original P 30 gypsy. Is it going to work? Did it work for you?
