The old eliminator was awesome as a downcountry front, I’m sure the new one is even better. I’m loving my dissector though, it’s the lowest spec version but it’s pretty damn good.

Anyone run the new Specialized Eliminator as a front tire? The refreshed eliminator looks a lot more like the new dissector and wonder if would serve as good a light trail duty front tire on the Ripley.

On a short chainstay bike you get a shorter wheelbase for the same cockpit size and head angle, so it's less stable and cuts a shorter turn. Your feet are closer to the rear wheel so it's easier to feel where it is. It's easier to push in and overwhelm just the rear tire, because when you push with your feet that's where the weight goes. You can turn with your feet more. You don't need to pull as hard on the bars to transfer weight or lift the front. That's what flickable means, and that's what people generally like...

Not really an issue as much as it would be a welcome addition. It is somewhat easy to burp Intend forks by loosening the top nut a bit with a 10mm socket and pushing down. Better than flipping the bike over and using a little zip tie in the wiper seal. The Italian Guy puts bleeders in the crown. Speaking of Intend forks, I was at Bootleg Canyon in Nevada this past weekend and there is a trail feature there known affectionately as The Poop Chute. It's a jagged solid rock waterfall full of notches and ledges. It has a...

I just filmed the Push Nine One video on a 60mm stem and it worked fine.

When I started diving deeper into all of this bar and stem geometry when I designed our bars, I built myself a handy little tool to play around with cockpit geometries that takes bar roll into account. Stack and Reach is taken into account, depending on bar roll, but I have not yet found a way to calculate the sweep angles, as a function of bar roll. Either it's very complicated or I am just not seeing the forest for the trees. Brain gets mushy after some time of trigonometrics, espoecially in excel. But it's quite fun to play with.

Here is your difference in steering bwetween a 70mm stem and a 35mm stem with straight 800mm bars. A video to make the scribbely lines more understandable: https://photos.app.goo.gl/bYf6TE4obQUwvhJG7 As you can see, the rotation diameters are virtually same (406mm vs 401mm). That's about a 1% difference. Your hands will travel about the same amount: 212mm vs. 210mm for a 30° handlebar turn. That's less than a 1% difference. What is slightly different is, of course the the "angle of attack" from which your hand will start moving, but that is because a longer stem will stretch your upper body position...

I've found a bit of a paradoxical relationship between bike length and stem length. The longer/slacker the bike, the more I want a longer stem as the bike generally has a higher F/R ratio and as the longer stem allows me to place more weight over the front wheel. On shorter wheelbase bikes or bikes with a longer chainstay, lower...

I can speak to clothing as I run a tiny MTB apparel brand, Abit Gear. The short story is that for USA brands, tariffs are making it a royal PITA and covid saw a glut of inventory that isn't yet cleared. Sure, margins are good on paper, but you have a SKU problem with apparel do to size and color variants, you have to carry a lot of aged inventory, and fight discounting from competitors more than with hard goods. For technical apparel, China is, by far, the best quality. Most of the technical apparel factories are in China. They...

I’ve run a single bike with a fairly large range of FC/RC ratios. Having a the ability to change the rear center +10 and +20mm means all other factors stay the same (bar, stem, spacers, etc), so having the ratio range from 1.88, 1.84 and 1.80 respectively. All these setups rode noticeably different. And in my experience, the longer rear centre's meant a higher bar heights to achieve a similar rider balance point. All of these setups were rideable for me absolutely. But personally, the longest chainstay felt too long and I struggled to get the weight off the front...

2/3/2026 9:28am

The cannibal at $52 is a great tire. I'm a fan of the radial MM but if you prefer tires with a locked in cornering feel and a supportive side wall, it may not be for you. I think the radial MM is better at slower speeds where mechanical grip is favored in lieu of support. Michelin tires might be worth considering. The MS is a better version of the Magic mary imo, with more support yet still supple. The MH is more similar to the other tires you mentioned - has a pronounced channel and provides locked in grip...

I've been riding a yet to be released eBike with the TQ60 system, but I set it up much like you have on the TQ40. Mode 1 is set to +100 watts at a 1:1 assistance and Mode 2 is set at +200 watts with a 1:1 assistance. This bike is a bit heavier than the Rallon RS, but has a 580Wh battery. I can pretty much ride all day on that battery if I use Modes 1 & 2. I still have mode 3 at 350 watts and a 1:1 assistance. I'm loving this bike on technical high desert...
