Ryan Burney Liked a forum topic MTB Frame Compliance Analysis & Discussion

Hey, I’m Ryan Burney. I’ve spent eight years as an engineer for full-suspension bikes, working on some fun projects, like developing the flex Horst link for the Cannondale Scalpel and being lead engineer for the latest GT Fury downhill bike. With over a decade of downhill racing under my belt (even made it to one World Cup—though I didn’t qualify so I stuck to engineering), I've had the pleasure of racing alongside the Vital crew, like Jason, Tanner, and Dak. Below is a photo of me, being slower than Dak. These days, I’m focused on my own projects, but I...

Nice to see the nerds are out in force. Fun topic and data set to discuss, so thanks for that. I deal with these sorts of "basic" data sets and the questions that come with them regularly at the World Cups as that is a big part of my role as coach at the races. The general lack of rigour and understanding of causality, causation, error, trial-to-trial variability etc.. at the races and generally in the bike industry is pretty surprising. But sadly, strict materialist/reductionist/mechanistic philosophies dominate without any awareness of that domination for a lot of people I won't...

Early observations and new questions With the benefit of the big picture and despite the funny business with the "time" axis having a misleading scale, y'all can just see that Bike Setup B approaches and maybe even ends up faster than Bike Setup A, eventually. I'll show how I did the statistical tests in the next post and ask if it seems convincing and how you might have done it differently. But I think some cool things happened in the early observations. Here's when the parts started appearing that I think might help others as they think about their testing...

Why am I sharing this, and why might another rider want to read this? I'm a (modestly) credentialed, (modestly) working scientist with no present affiliation to the any part of the bike industry. Teaching quantitative reasoning and technical communication skills is the lion's share of what I do for work. I'm not a 'sci-comm' professional trying to drive attention toward a podcast about bikes or a bike youtuber trying to grab attention by deploying keywords like data or science. I don't have a vested interest in either bike setup being faster than the other. So let this be my attempt...

jeff.brines Liked a comment about Feature 6 Mountain Bike Brakes Tested With Data - Vital Test Sessions

Being I'm sick (and bored) I wanted to add a few more thoughts. 1) Anyone looking for raw data, its already been done and the link is posted here. Zee Germans live up to the stereotype and absolutely crushed it if you care about being completely quantitative with respect to a brake test. 2) The real reason I read reviews on Vital is because guys like Jason are legitimately fast, ask a lot out of their equipment and frankly have great taste. Its like reading a review of a restaurant from a food critic you jive with. While adding some...

Oh, this is my specialty. I make data sheets and written guides about buying a bike. Your best bet is finding a Giant Fathom, Trek Roscoe, or Specialized Fuse secondhand. I've even seen that base Fuse with the coil for under 1k on their website. If you're REALLY struggling to find anything you can always fall back on the Poseidon Norton as a bottom of the barrel stock build that you can basically upgrade frame up long term. The wheels and drivetrain are more solid than I thought however so yeah you're basically just looking at fork, brakes, dropper and...

Its interesting you bring up the Balance. I have one built 180/170, coil, burly. I also have a Pivot Switchblade. For the majority of my trails in Durango, which are mostly singletrack, blue or black rating I prefer the Switchblade. It pedals better, corners snappier. The Balance on a blue is so boring, it hates it. But when I get on that Balance on a proper black or higher trail downhill its so fun, not necessarily faster, but more fun. It's just so heavy uphill that I just don't grab it as often. The % difference in bikes is typically...

I'm fairly certain I want something in the 150-160mm rear travel range. This is actually being decided primarily due to me wanting a 160mm fork. I think having a fork around 160mm with 36mm stanchions is where I want to go, and a balanced f/r suspension seems nice to me, especially if I want a 27.5" rear wheel... I would be open to the idea of a well-managed 140mm rear suspension platform. For example, 140mm with rearward axle path. This is also being affected by which bikes are available these days with a gearbox, as I've committed to that being...

If you'd asked me a year or more ago what my ideal travel bike was, I would have quickly answered a 170mm enduro type. Beginning of '23 I got a Nomad 6 and love(d) it. It pedals really well for how much travel it has, but has enough suspension that it can erase poor line choice and handle a few days per year at the bike park. But then this year I got a Heckler SL ebike (which is basically the new Bronson with a mid power motor), and damned if that thing isn't more poppy and playful than the...
