    Sorry if this has been addressed before, but I have always wondered when and why bicycle tires went from 27″ to 700c. For me it seems like it happened overnight!

      For a long time, there were two competing standards – the French metric one and the Imperial one. In some cases, the differences were significant enough that both survived – see 650B (584 mm) and 26″ (559 mm). However, 700C (622 mm) and 27″ (630 mm) were so close that there was no justification for both. In Europe, it was always 700C.
      American and British bikes were split: high-performance bikes used 700C – mostly because tubular tires came only in that size – while touring bikes used 27″. But as people started to travel more widely, the lack of availability of 27″ tires and rims in most parts of the world became an issue. There are plenty of stories of riders stranded in France with a twisted 27″ rim, and no way of getting a replacement. Add that high-end racing bikes used 700C all along, and 27″ fell from fashion.
      You still can get 27″ tires – but there never have been any truly high-end tires in that size, and there certainly aren’t now. Your best bet are Panaracer Paselas… Many older touring bikes can be converted to 700C wheels, especially if they use cantilever brakes. The brake pads have to go down just 4 mm. In fact, Jack Taylor used the same frames for 700C and 27″ tandems – the brake pivots were placed so that you could use either wheel size.

      Among the “performance grunge” set of riders decent 27″ frames are often sought after, since with a modern 700c wheelset they can usually clear at least a 32mm tire, and sometimes a 35…A set of long reach brake calipers and away you go!

    This is great news! I’ve been waiting to buy some Extralights. Problem is I’m choosing between Bon Jon, Barlow and Snoqualmie – to run tubeless for pavement, smooth dirt, mild gravel. Trying to balance more width (good) with minimal rotating weight (a lot of climbing in mind). But the listed weights on the site confuse me. Why don’t the tire weights go up sequentially by size?

      I would get the wider ones – more grip and so much better on gravel and rough pavement. The weight differences are very small.

        Jan…on my 21mm wide (internal) rims, will the Barlow likely expand to +40mm wide? My frame can only take up to ~38/39mm measured tire width. Thanks.

          If you run them with tubes, they should come out to about 38-39 mm on your rims. Tubeless, they might get about 1-2 mm wider. If it’s really tight, I’d recommend the Bon Jon Pass instead.
