This ignores that the taller rider would also run a higher seat height because people get taller from the waist down along with from the waist up. The taller riders taller seat height would need a taller bar just to maintain being level with the increased seat height. Even a short rider having a...

100% bikes don’t scale proportionally at all! I’m 5’8” and I find for my height the Gen 1 150mm is my preference typically on a 460mm - 480mm reach mtb. This puts my bars above my saddle at climbing height. Both those riders are showing their saddle at climbing height which is directly...

Not really, as there aren’t any -15mm stems on the market, and the closest thing is explicitly advised by its manufacturer not to be run in reverse, has no height adjustment, only accepts 31.8mm bars, is lower even at max allowed height, and doesn’t even cost much less… The reason I made the RR...

It can yes. In fact, this is a great link to a Reversed short short stem that can be run on an uncut or extended steerer. It even has a window for spacers put above or below the steerer tube clamp to fine tune height down to the mm and can be used with whatever bar you want in 35mm diameter or...

A bar with enough backsweep to put your hands in a similar position to the RR stem of about 40mm - 55mm behind the steering axis would have such a large amount of backsweep, ie. about 22 degrees or more on a 35mm stem, that getting a good bend in the elbow in the attack position would be quite...

As you mentioned AI isn’t always right. It’s best used as a way to aggregate large amounts of well established information concisely. Tuned Reversed offsets for stems are a new thing, so it doesn’t have a lot of credible sources to pull information from in making claims about them. It’s been fun...

Simply turning your existing stem around will not achieve the same offset as the tuned Reversed offset of the RR stem or achieve the Raised height. I tested anything from below traditional height to about 80mm taller than the taller Gen 1 150mm RR stem, and 70mm offset forward all the way to...

If you rolled a really tall riser bar back to achieve a similar geometry, you would need to roll it from its notably in front of the steering axis position back to about 40mm - 55mm behind the steering axis to achieve the same hand to steering axis relationship. This would give a substantial...

The RR (Raised Reversed) stem is not the same as a very tall bar. The RR stem is both Raised and Reversed. Due to this your hands will be notably behind the steering axis of your frame instead of in front as they traditionally are. A really tall bar or even a long steerer tube with a bunch of...

I’d say go for the Gen 2 90mm RR stem full -15mm offset, and likely even plus some spacers. I’m also 5’8”, and I would probably run that bike with the Gen 2 90mm RR stem and 60mm rise bars maybe even plus a few spacers for my preferences. You are within the range for sizing on that frame that I...

Awesome! I’m glad it’s coming along nicely! It will only keep getting better as you spend more time getting you and the bike dialed into it. 😄

Howdy. 😊 I’m always open to discussion. How tall are you, what reach and stack did the frame have, and what were the combined stem and handlebar heights tested? Also, did you make any suspension and tire pressure adjustments during those tests? Generally I feel we agree more than we disagree as...

Awesome! When you get a chance, post a full picture of the bike preferably a side view. I’ll see if there are any glaring adjustments that I recommend for helping some of what you feel so far such as seat or bar position. The points in section 2 I’d say will largly reduce with time getting used...

If you buy any of my products, and we find working together that we can’t get you to a point that works better for you, you can return it for a refund minus shipping. 😉

Preorders may start in a month or so, and likely will be in 80mm and 100mm Raised heights with a -15mm Reversed offset. Details are still arguably a bit up in the air as I am in prototype stage, but it’s looking promising. https://www.instagram.com/reel/DWZlJvuDLI-/?igsh=NTc4MTIwNjQ2YQ==...

Awesome! 😄

That relationship between hand position and wheel flop is understood best through a new concept I’m introducing to steering dynamics that I call “Hand Lead” and “Frame Lead”. “Frame Lead” is the exact same as the trail measurement you are likely familiar with just conceptualized as the frame...

100% It’s a whole set of factors. This is part of why I’d say it’s more similar to getting a new bike with a different geo rather than just a stem change as it feels like much more than just switching from say a 40mm stem to a 35mm stem… 😅 The main one is the tuned Reversed offset for best...

The thing you are aiming for is balance. If the front and rear compress evenly when bouncing up and down loading through your feet, and the front doesn’t feel too stiff and the rear doesn’t feel too soft with similar travel usage front and rear on trail, then you are likely in a pretty good...

TLDR: The RR stem gives more consistent front end loading, over a traditional stem as you steer and counter steer for balance. You need to setup the front for the level of load it gets at neutral to get good traction. A long chainstay gives a smaller differential between max load on the front...
