All

It's not so much that 2 layers were added, its that now both of the 2x67epi carcass layers are now extend ontop of each other under the tread cap (before it was just one layer that extend to the end of the lap.

I’d love to see a shoot out of trail bikes using the same linkage designs. It would really interesting to start to dig a bit deeper as to what sets them apart - quality control, kinematics, maintenance, etc etc.

visual summary

Zerode are launching a new frameset, looks like two travel variants, 160 and 140mm. Shadow and Shadow Trail. 450mm chainstays on the large too. Internal frame storage too. Curious what the kinematics are. Looks pretty cool imo! https://zerodebikes.com/products/shadow-origin Rob continues his streak of only launching bikes like a month or two after I buy something else...

You mean chainstays?

This may not always be the case, but a lifetime bearing warranty often brings an incentive for the manufacturer not to have to supply 20 sets of bearings per frame, so they design and spec better. Frames with bearings in linkages are my preference provided they are quality - not much point having bearings in linkages if the pivot axle is wearing a groove in your frame. In my 4 years on an Arrival I have replaced one set of bearings and ridden a lot in loads of conditions. Bearing quality, bearing seat tolerance, and frame alignment are important. I...

In the above picture, you can see the pushrod, which is used to adjust the bite point. Clockwise advances the piston in the bore, counterclockwise retreats it. Adjust it too much and the seal on the piston can block off the timing port hole, circled in red, effectively closing the brake off. Hayes made much about setting this gap between seal and port holes as minimum as possible from the factory and recommend against mucking around with it. Bite point adjustment does nothing to the caliper pistons' location. That is designed into the seal and seal seat interface and cannot...

Madrone with a DH set up is rad!

B Practice podcast from South Korea went up yesterday, YouTube vid is almost done uploading. Dak's travel home + driving to Mountain Creek delayed recording but we still love him. Sounds like he's playing a bit of catch up to find some comfort before the next major block of World Cups. https://www.vitalmtb.com/features/every-run-race-run-vitals-b-practice-…

Might be one in the minority here, but I always like having a bit narrower field of view for videos like this. Having the nearly 180 degree vertical fov and extreme fish eye affect because of it is off putting to me, and part of the reason I hate 360 degree cameras being used for pov shots. Great riding and love the follow cam for the stage though!

Looks to be a 170mm mullet park bike

Mondraker releasing what looks to be a big travel bike or just a single crown Summum tomorrow

it is if you know where to look for it.

I started a new thread to keep the conversation going around TPC’s without bogging down tech rumors. Discussions around metals are also welcome! Materials and Processes for Cyclists

political posts and responses deleted. take them to " off the bike"

we were talking on our ride last night about avinox, and a couple well placed industry friends was saying that there's a real feeling around that they're about to devour the industry and in particular (SRAM/Shimano/Bosch/etc) as a whole given how much engineering resourcing they're putting into the whole thing (Amflow, Avinox, etc). Granted I'm deaf in one year so hearing the fine points of a conversation at speed can be challenging, but they were saying they have a many many hundreds or thousands of engineers working on the motors, batteries, frames, complete bikes and all the brands playing me...

One thing missing here is the fact that with the proliferation of composite know how, there are more people around able to safely repair a wider range of issues. Rather than pretending we are recycling carbon bikes I’d love to see more frames designed in ways that facilitate repair. Repair is verifiable in a way that recycling is not, it is cost effective for everyone concerned, and it is as close as you’ll get to good for the environment. It probably flows on to other design decisions to ensure repair is viable (like bearing placement, etc etc), but designing bikes...
