On August 29 a US tariff exclusion on items under $800 was eliminated. Items arriving after that time will be subject to the various tariffs in effect. This has created chaos for shippers. Many nations have suspended postal package shipment to the US. Full list of countries suspending U.S...

I'm just going to post a photo of this thing. If it interests you contact Rene Herse. The latest thing in Retro parts.

I just like to try things, and I like my bike to be different than others. At least if it's better for my own purposes. The bike is a 2004 KHS Team Issue Softtail 26" XC bike. Light weight for an MTB, Sturdier than a road bike. Gravel racing has opened up some possibilities for me. Rene Herse...

Solfiane Sehili is trying to set a world record biking unsupported across Eurasia. Portugal to Vladivostock. The only udpate along the way required the interviewer to hop on a bike and talk to him while riding. He says nice thing a bout the Highlands MTB race. It's his favorite because it's the...

Having modded my old 3x8 XC bike to 1x11 using a Zee M640 derailleur intended for 2x10s DH bikes. I wondered what if anything I was missing out on. I ran both setups at Sheldon Brown's Bicycle Gear Calculator. https://www.sheldonbrown.com/gear-calc.html 42x11-42t 11s top gear = 26.5mph @ 90rpm...

Latex inner tubes have been around forever. Daily air loss is a known issue. Delicate too. But comparable performance to tubeless (weight/ride/speed). From my Ebike experience, tubeless sealant in the inner tubes works very well to prevent flats. Enough of that topic. On my Vintage 26" XC...

UCI Limits road bike tires to 31mm. “With ultra-wide tires, speeds in gravel races are becoming almost indistinguishable from road races. We should never have allowed the disc brakes that made all this possible!” https://www.renehersecycles.com/uci-limits-road-bike-tires-to-31-mm/ So UCI is...

I'm going to focus mainly on the axle mounted Saint M800, and Hone M600 derailleurs. They're both Rapid Rise which I prefer, but M801, and M601 are the High Normal versions. They're both axle mounted but the Saint is 10mm Thru Axle, and the Hone is threaded onto a longer (186mm) solid axle (not...

Why the M640 Zee SS cage? It's a DH rated part. No plastic. The clutch cover and lever are both metal. The SS cage helps keep it up away form curbs and things on 26" bikes. This test confirms it works with up to 40t cassettes in 1x setup. Also 10-11 speed Shimano comes out at the same cable...

These have been around BMX for some time (2002), and Trials bikes too. Generally regarded as the best hard use 1 speed freewheel. They're still made in USA. Parts are readily available. Standard English freewheel threads. They do wrap around the end of the threaded freewheel boss. So a spacer...

Hub motor Ebikes still use the English threaded freewheel format. There are wider range, and higher gear count freewheels available due to this. 7,8,9 speeds and ranges up to 11-34t range...

If you have an old set of Mavic MTB whhels, or their hubs that required a spacer behind Shimano 8/9 speed cassettes, you already have an HG11 Freehub ( IDK if Mavic road stuff is the same or not?) Now Shimano road, and MTB 11 speed hubs are different. Road uses the wider HG11 spline freehub, but...

My 2004 Gary Fisher Solstice 26" comfort bike ahd Avid BB7s added to it when new. It's also had a 1500W motor a few years ago. The BB7s are still there. But the stress of the motor led me to a few upgradesthat I feel keep them on par with all but the be$t hydraulics. First off there are 2 series...

Rene HERSE Cycles is a builder of custom Touring CX Gravel and Tandem bikes. They're located in Colorado US. They're coming from a background of traditional road racing bikes. Center pull brakes, rigid bikes, etc. I'm not plugging their products. ( TBH most of their stuff doesn't interest me)...

These are both obsolete Shimano technologies. I've used them both (separately and together). There are some similarities, and a couple differences. I'm still using them on current bikes. A 2004 MTB Ebike conversion, and a 2004 XC softtail converted to 1x11. WTH is it? Front Freewheel System...

1970s Schwin FFS vs. Di2. video. I did a search here for this and found nothing. Raleigh did some bikes with it but Schwinn and other US builders used it quite a bit. https://rode-bike.com/shimano-front-freewheel-system/ Some of us are adding this to mid drive Ebikes (which already have the...

I know chain lube discussions can be like religion for a lot of people. At Zero Frictiob Cycling it's a science. They test chains and lubrcants and publish the results. They earn their living offering the best of these to racers. They call ZFC "where good lubricants go to die" because of how...
