  • Seen at MOSI today, looks wrong even though it'd still function ok I guess?

  • I'd be surprised if anyone still makes 1 inch pitch chains.

    Technically, they weren't 1 inch pitch but 1/2 inch pitch with every other link being solid, i.e. without a space between the side plates for the tooth to sit in. They were favoured by track racers as it was thought that it produced a stiffer and thus more responsive chain. From the side they look the same as ordinary chains unless you look carefully.

    A bit like oval chainrings - a passing fad.

  • most likely on there as those old skip link chains are nearly impossible to find.

    that 1/2 chain makes it usable at the end of the day, surely that cant be a bad thing?

  • Don't let the weight weenies see this, they'll be getting the files onto their chainrings before you can say "scales"

  • I understand the chain makes it usable, not disputing that... however this one is hung on a wall in a museum, not going to get ridden. As a period piece on display that chain spoils the look.

    There's similar Chater Lea on Hillary Stone at the moment:

  • fair enough like, not the easiest or cheapest thing to track down tho to be fair, probably not a museum with hella budget for old chains and the like.

  • Would there be a market in making Inch Pitch chain, do you think? Especially if chain sets were made for today's bikes. I've always liked the butch look of an Inch Pitch

    There used to a track tandem in the transport museum up here in glasgow that had a freewheel and mtb spds pedals. I don't think technical accuracy is high on the priorities when they set up exhibits.

  • normally the teeth on a 1" pitch are 3/16th therefore a modern half inch x 1/8th chain wouldn't sit comfortably on the ring, maybe it's a moped chain that's been hybridised?
