11/22/2024 12:43pm I think it's more the fact that if just cemented Lewis as a copy cat brand. Their only 2 products are ripoffs of extremely expensive high end western designs made by small companies which just doesn't feel good. Like what's next, they release a bike that looks exactly like a V10?

11/22/2024 12:36pm Do you think it's possible to make a test frame where you mount the rear triangle to the front with bushings that can allow the rear to turn 2-3 degrees? I'm imagining a dual link frame design so you have a solid triangle and before it joints with the 2 short links you make a link that has a bushing...

11/20/2024 1:17pm I wouldn't say it's doing weird things here, but it does look weird. It's "just" flexing. But it does look a bit hectic. It's a perfect illustration as to why frame compliance and wheel flex is important. The way I think about it is this (could be totally wrong), he's pushed aggressively hard into the corner, the front is tracking...

11/16/2024 6:58pm Yeah I agree with this and with @Erwan_Ghesquiere views, the companies can definitely test, but I do understand if they don't publish the data. I think an interesting point is there isn't really an engineering or rider based objective standard of what is good or bad flex yet, we are still at the stage of figuring out whats good, let...

11/15/2024 9:08pm To play devil's advocate a bit I think the reason Ochain and the like don't publish hard data is obvious, it's really noisy and incredibly hard to measure it well. Also a large part of these products are psychosomatic, placebo induced often, like hand fatigue, grip levels etc. It's a feeling that can't really be measured easily. It's not that...

Henry at PB, and many others, including very good friends of mine who are bike mechanics/wheelbuilders, all seem to think that increasing spoke tension will increase the stiffness of a wheel, and vice versa. They all rely on some sort of "feel" related justification, and post hoc rationalization of why they think the tension is leading to what they think they are feeling. I am still unconvinced. I am not sure if you have ever seen it, but Damon Rinard (who has been a lead engineer at many bike companies) designed a rig back in the 90s to test the...

11/12/2024 11:48am Do you guys measure flex in a lab setting when designing bikes? Or perhaps more interestingly do batch testing for flexiness during production. I know from first hand experience due to frame alignment and normal manufacturing variations some bikes wobble (not flexing I know) quite a bit when shaken from the BB or read wheel due to how the pivots...

11/11/2024 11:34am Well you ideally wouldn't want to be liquid, you would want to have large amounts on inventory purchased pre tariffs to hedge against the price rises. You don't need liquidity post tariff as everything is now expensive and you won't want to buy it. I think we've know for a while people like buying higher quality made in USA/EU etc...

11/8/2024 2:02pm I think we all know universal tariffs will be universally bad, but the really interesting aspect is how America's truly believe their economy is in bad shape, when in reality is the envy of the told and by far the most successful over the last few years. If the tariffs come in hard and fast I definitely think it will...

11/7/2024 2:10pm Very badly. Makes all imported frames and parts more expensive, passes on those costs to consumers. Frames and parts in the country are already discounted to sell, meaning they won't be ordering any more at a 10%+ increased price as they can't already move the cheaper ones. A universal tariff is a horrendous economic policy

11/4/2024 12:30pm Interesting that you think 90% is 29er. Down here in Tassie I'd say it's close to even. Lots of steep tight twisty trails so MX bikes just make so much sense. We don't really have open high speed trails as everything is cut into rainforest often by hand. I'd say for me I'll always be a MX rider. I'm 177cm...

11/2/2024 5:53am That would be true, if it wasn't the case Frameworks said they were making 80 DH bikes as that's what was ordered, and then they went on sale to the mailing list and online after that. They then said they would make more than 80 if there was enough demand, which is what everyone manufacturer does, as they release during...

11/1/2024 2:49pm Not to nit-pick but just want to point out that what Neko and Frameworks are doing isn't some unique "drop" model, its literally how every company using an OEM supplier works, they just inform you of quantities beforehand. Unless you pay an OEM for a an entire production line, they will make/assemble whatever quantity you ask for in batches, and...

10/31/2024 2:47pm yeah i guess not, you only compress a a small portion of the tyre's total volume when slamming into a rock. Bummer.

10/31/2024 12:57pm This actually looks like a solid product. I wonder if it can graph the pressure in the tyre (i.e high speed sensor) to see how often you bottom out tyre into rim from impacts.

10/24/2024 1:48pm The Marin Alpine trail XR has a nifty +- angle cups for a budget frame. So it's totally doable even at low cost. I really want a Rocky because of the headset adjust meaning you can size it perfectly, just wish it was 6.5k aud and receives mediocre warranty standards in aus.

A 5 m/s wheel speed input, which is reasonably fast, although not impossibly fast at all, 30 kph is right around where you wouldn’t experience kickback when in a 10t gear. 8 m/s is about as fast as you’ll ever see if I remember right. That would correspond to 49 kph. This is all using a typical leverage ratio at 50% travel for a 170 mm bike with a 65 mm stroke shock. I’ve got something I’m working on right now that will have a massive range of leverage curves and axle paths. I’ll try and remember to share some...

10/20/2024 6:15pm someone on this forum? Or Steve from vorpsrung went through the math of a specific frame with actual numbers to highlight two circumstances, 1 of kickback and 1 of no kickback. For my memory it was like a 5 foot drop and the "cutoff" speed where you wouldnt see kickback was like 32km/h or something? Its just a formula you...

10/19/2024 2:13pm I read this twice and I still have no idea what you intended to say other than jaded garbage. You definitely have truly lackluster diction.
