8/12/2025 11:49am Interesting timing as I have been going through some hub/axle stuff as well. Fully Floating System What is found on inverted dirt bike forks; the fork axle can pass competently through the non-disk fork lug, and the hub end cap does not make contact with the ND fork lug. When the axle is tightened, the hub is pulled against the disk side fork lug, just like the Cannondale Lefty. Hub width has no effect on chassis alignment. Non-Floating System A system where the fork axle bottoms out on the outside of the fork lug and squeezes the hub between the...

8/12/2025 11:49am That's a pretty damn informative post, thanks. I only know just enough to be dangerous here... so please bear with me. Question, I have to assume that there is an impact to stiffness based on how the front hub axle/end cap interface works? I've long thought that the end cap design of the dt350 is a standout weak point of...

8/11/2025 9:40am I had typed out a big post to this thread... and somehow hit refresh and lost it. So I'm going give the abbreviated version... I have been testing a 170mm push 9.1 (v1 with the air hbo) for the last week and have 4 rides on it. I have been testing it on my SC bullit so that I could...

8/6/2025 4:42pm I am a vest guy myself and I have a 1.5L (2.5L gear) camelbak chase vest (the original one, which is slightly better then the current one). I recently got a camelbak chase 8 vest as a replacement which is a 2L bladder (6L gear). I use either depending on the length of ride, combined with a water bottle on...

8/6/2025 3:08pm If you don't need 3L of water in it and can make do with ~1.5L of water, vest-style packs are awesome and don't move around at all. You may or may not have noticed that as EDR has gone back to long-ass days on the bike, a number of the racers are running these now. I like the Evoc ones (actually own 2 sizes for more/less storage capacity). I previously owned a CamelBak Chase and didn't like how only 1 side had zippered chest pockets and had issues with stuff falling out of the non-zip side.

8/5/2025 1:58pm Thanks for mentioning that situation on the 38. I have yet to service a 38 air spring without finding nearly all of the bath oil trapped in that space between the air spring body and the stanchion. The interesting part of that for me, is that space is one of the things that helps the 38 air spring work so...

8/4/2025 1:37pm Yeah, those weep oil and will not stop. I left them on for 6 months just dealing with it expecting it to stop at some point... it did not and I just replaced them. Oddly, I had previously used these with good results with no issues... only the sets I bought in the last 1.5 years did this.

8/4/2025 1:00pm You're not using push low friction dust wipers are you? I had 2 sets for a 36 and 1 set for a zeb (38) that would weep oil both during rides, and also during storage (bikes are hung vertically on steady racks). I swapped to dual compound skf seals and have not had the problem since.

8/1/2025 12:37pm Have you noticed over the past few years that there has been one frame dimension that people obsess over? One year was head angle, then reach, then seat tube angle, stack now it's chain stays.. Now seeing more people who are realizing that all those numbers have to work together...

7/28/2025 3:11pm The right casing for terrain, weight, and riding style is really important. An often under looked factor is tire pressure. This probably doesn't apply to most folks in this thread, but the gen pop frequently has unrealistic expectations of what tires should be able to do. Such as riding XC casing tires at 18-22 PSI on the front range of Colorado when they're a clydesdale, and then surprised Pikachu face when they pinch flat.

7/28/2025 2:53pm Canyon will be the first, it'll be called the phase shifter. No one on earth will use it, except for Jesse Melamed... and he will beat everyone's pants off with it.
But seriously, canyon is primed for some sort of real time, variable leverage rate situation with their shape shifter. KISS... amirite?

6/30/2025 4:44pm Keep in mind that the stages from the last round of this EDR had what I would consider more mid stage climbs then normal. If ever, there was a round with stages where an extra 3/4lb of weight would matter, this may have been the one.
