Just trying to get hold of a headset for a current build. The frame seller states that the headset is 1" inch x 25 Threads per inch (TPI) I checked Sheldons site and he doesn't even recognise 25TPI ? Would a 24TPI headset work with the fork ? Thread is English ?

Whats the frame? Unless its really old ie from 1960s or earlier, its unlikely to be something so weird.

I'd ask how does the seller know its 25 TPI? Get him to double check that fact as its not a even an uncommon thread size (French and Swiss are 25.4 TPI)

Theres no bike pictures on that thread just brakes and a deraileur.

Sadly don't know much about Gazelles or Dutch bikes in general so not too sure what a common threading would be. But I do know that these were high quality professional raced machines so I would seriously doubt that a 1980s bike would have anything other than English or Italian threads. All I can suggest is getting the current owner to double check.

damn the bloke has changed his website he shows pictures of his ebay stuff and obviously updates it once he has sold the bits.

I'll double check with him he does seem knowledgeable maybe it was a typo ?

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot
