I’m reading “Bicycles in the Bush” I've read "Lost Cyclist" but hadn't seen Bush. Thanks for pointing that one out. I guess the revolutionary technology of pneumatic tires spread faster than I thought back in those pre-internet days. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Thanks, Phil. I need a new rear wheel for the 135 spacing fixed/fixed Phil KissOff hub.

I wouldn't worry about it. Try it, and if you find it's not working, go bigger, raise the pressure, or slow down. Fixed riding kind of limits the amount of speed trouble you can get into, anyway. My rims are generally 18mm inside, with 32 spokes, and I don't have wheel troubles. Cliffhangers are probably overkill. Don't you already have wheels? The bum wheels I've had have been second-hand machine-built Deores, and they'd break spokes on the road. I don't generally ride with a rear load, though.

Excellent points, Daniel and Jim. Jim, there are quite a few photos of Dunlap tire ads in the outback in that era. I’m reading “Bicycles in the Bush” and “The Lost Cyclist” and the things they rode through with essentially cyclocross tires are amazing, and with far greater weights.

My guess for late 1800s Australia would be solid rubber, given that Dunlop started commercially producing pneumatic bike tires in Ireland in 1890, IIRC. > — My rear wheel plan is a cliffhanger, which has an inner width of 25mm. > Will this work with a 38mm tire, or be too wide? > Probably too wide. Here's a Mavic engineering article on tire/rim width: http://engineerstalk.mavic.com/en/the-right-tyre-width-on-the-right-rim-width/ I agree with Daniel that pinch flats are going to be a problem with a load and narrower tires. I don't know that tubeless would help with tires at that width. You can pinch a tubeless on a rock and have it burp out the sealant. Also, it's not just total weight but distribution of the weight. With all the load over the rear tire, it's going to take more of a beating than if the load was distributed more evenly across the bike. Might as well try it but take extra tubes and a patch repair kit. jim m walnut creek, ca -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Two risks come to mind: 1. Pinch flats. This will be mitigated a bit by increasing your tire pressure but offroading with that much weight on a 38mm tire might just warrant exploration into tubeless territory. 2. Your rims will take more of a beating.with the narrower tire. I'd recommend extra spokes and tools for their installation in your kit. Best, D.
