$280 USD for the new Speedframe? Does it incorporate a mini air conditioning unit? A button that summons a bike butler to clean and store your bike after you ride? It must come with some kind of wild premium feature to cost that much.

The RS has MIPS Integra Split “which combines an impact-savvy, dual-density foam layer and a Low Friction Layer between the two, to reduce rotational forces in a crash that would otherwise be transmitted to the brain.” The other speed frames have MIPS Air Node, which actually increases your likelihood of a brain bleed as punishment for not buying the $280 helmet.

I also recognize that top link but can't place it. But I've absolutely seen it before.

It looks a little like a Vitus Sommet 297 link, but it looks a lot like an Airdrop Edit MX link:. Did I scroll through this entire list of 186 bike companies to find these two examples? Maybe. Did it feel better to scratch that itch, and help me avoid doing homework? Absolutely.

Looks like just the mips integrated split.  All other features are the same (fidlock, sunglass storage, etc)

No idea why someone was downvoting you youre 100% correct. New speedframes are a huge improvement, they were gunning for the most safety and they claimed top spot at a fraction of the price of the ares. Both dual density options are 1st and 2nd atm at virginia tech. They fit well, vent crazy and are just generally way better than the outgoing model.

Has anyone seen a review of the Oneup new clipless/clip pedals besides what was discussed on the podcast?

One ride in they seem great. They do all the things they say they do and have a nice positive entry. Worth a shot if you're in the market for a clip pedal with a bit of platform. I'm pretty happy so far. 

Not as easy to unclip vs a mallet, but I'd expect them to wear in a bit still yet. They feel like they wouldn't have the surprise unclip of a mallet through haha.

Hm, does the seatstay mount even clear the chainstay? Obviously it has, it just looks a bit weird from this angle.

This, i just spent 3 days on mine, they are considerably better than any shimano offerings in the 'ride feel' category IMO.
I hated Shimano SPD's because of the freeplay they have before 'float' kicked in.

The only Thing I've found is how tight full loose is - kinda wish Oneup had gone slightly less tension as full tight is Knee/ankle killing tight.
I Normally run Mallet E LS's and they are perfect tension for me.

There's a new model coming from Pivot, called "Trailcat". 

It's a full-suspension 29er trail bike and will be offered in an "SL"-Verision with 120 mm and a "LT"-Version with 135 mm of suspension travel respectively. Build kits are spec'd accordingly.

The frame geometry across all five sizes is rather conservative, as is often the case with Pivot. And while I won't disclose any specifics; just take a look at any of their current offerings, take an educated guess and you won't be too far off the mark.

Personally, I like the fact that they offer bikes for people who aren't convinced that overly progressive geometry is the way to go. But I'm beginning to wonder how popular these will be in the real world and how exactly that will translate to sales figures - especially considering Pivots ususal pricing structure.

Sounds like they are merging the Trail 429 and Shadowcat to simplify their frame production? I wonder if the travel difference is via shock stroke and/or a different link 🤔

I’m interested to see if/how they wear in over time. I’ve been on CB pedals forever and I like the looser tension on CB but I’ve rebuild my Mallet E LS twice already and lost count of how many cleats I’ve gone through. I’ve got two bikes so it’d be a bigger commitment to go to OneUp/SPD at this point haha

I’ve run them on a couple rides, (normally on Mallets) and I’m having some trouble disengaging from the OneUps if I leave some weight on the Pedals and rotate past 12 degrees.  My muscle memory is probably to blame, but it’s not inspiring confidence.

This is the point everyone makes about pressfit. But, I still dont buy it.

Why not just do a threaded? Makes it way easier for home mechanics. And as long as you have it properly greased/anti seizes and torqued. There is virtually no room for error or damage when removing it. There is way more room for error if you change a press fit bracket yourself. And a decent press fit bb tool is like $300-400.

I just dont get it. Maybe I am stupid, but is there a single benefit to pressfit? I dont buy that its lighter on trail/enduro bike, that argument isnt it.

I had two YTs, one carbon and one alloy, and both pressfit obviously. The carbon one had much better tolerances but I had to frequently replace the bearings because they just aren't great. Tried several types and none lasted a season. It was getting easier to press in the bb toward the end before I sold it which seems pretty inevitable. No matter how much grease you use, its going to wear out the frame/shell. The alloy one didn't have great tolerances, always had issues with bearings not pressing in evenly and eventually falling apart in the frame. Still have the bike but need to sell it. 

Current bike has a BSA threaded and its lasted much longer. Replacement will be so much simpler too and there's no concern of the shell gradually wearing away or being expanded out over time. 

I'll never get a PF bike again. 

EDIT: I should mention this was with 30mm crank spindle. Maybe PF is longer lasting with 24mm spindles since the balls can be bigger and maybe room for better sealing.

Using press fit on mountain bikes gave frame designers more design freedom, as they didn’t have to accommodate for bearing cup spacing. More room for suspension pivots, stiffness, etc.

I think a lot of those benefits canceled themselves out when chain guides and front derailleurs started fading away.

Add me to the list of people who never had a problem with them. On the trail, or in the shop.

Neko talked about optimizing certain aspect for different rider like how Angel like a different leverage ratio curve than he does.

This might be in a similar vein that one of the rider would prefer a higher anti-rise ratio than the standard setup ?

Also I can't wait for them to release for sale the bonded frames. They look so good.

It seems strange that Oneup didn't have people reviewing prior to the release so the reviews could be dropped the same day. I have really liked the components I have bought from the company.

Yeah never had a problem myself, but if you have a PF frame but want a threaded BB, WheelsMFG do a really nice pressfit bb where the 2 half's of the BB thread together making for a perfectly aligned BB.
Hope have some as well for a more pricey option.

I figured it was a test / r&d frame given the floating arm has 2 different mounts plus an adjustment slot

Yeah I agree. I already have a set, and they are mounted to my bike. Huge fan of other OneUp stuff, and not a huge fan of the saints - But I love the SPD standard, so I ordered a set as soon as the launched. 

But I am looking for reviews or videos on them, to see how they actually perform out in the real world. About 3 feet of snow where I currently am, so not possible to ride and test them myself.

I have basically the exact same press that I bought as a headset press, works perfectly fine. To press in BBs I usually use the Unior kit which has BB cups as well. It's slicker to use as it has a QR handle on one side so you don't have to wind it in all the way and it has dual handles.

As for press fit BBs, with 24 mm axles the cups aren't much of an issue. After all, Shimano started the standard. The cups have enough space to have enough meat to be thick and strong as the bearings to support 24 mm axles are fairly small. When you start approaching 30 mm crank axles, the clearance between the threaded part of the cup and the axle gets smaller and the walls can get fairly thing, possibly leading to less stiff cups and the bearings moving. Which can lead to eaten axles as well.

A big plus for press fit bearings (not specific to 30 mm axles, but for the above reason the most obvious one) is that the bearings are directly supported by the frame, there is no cup transferring the load to the frame. There is also more width available for the downtube to BB shell joint, so the DT can be flared wider, at least on the NDS side.

Yes, there are issues with dimensions, obviously, but if this is the reason to hate press fit BBs, why do we still have press fit headsets? Why do we have direct press fit bearings for pivots?? Not only do the two bearing bores on each side of the frame have to be the right dimension for a press fit with the bearing, the bore also has to be of the correct depth and the axial face flat enough to support the bearing axially. Surely if we cannot trust the frame manufacturers to make a single, straight through, stepless hole that is round and coaxial, we also cannot trust them to make pivot bearing bores correctly, which are even harder to get right.

Granted, press fit BBs were born because of carbon frames and are usually raw, which means it's cheaper to produce than laminating in an aluminium insert (or titanium or stainless steel, if you don't want the aluminium insert to corrode and fall out of the frame), but if you can laminate in a threaded insert, you can laminate in a metallic tube. Which you can then bore to size after the fact (like you do with cutting the threads) and you can do that in a single operation from one side of the frame, which is machinist's hole drilling 101 - do as much in a single operation/piece setup as you can. All pivot locations are drilled/machined from both sides, which is a cause for coaxiality issues.

As for removing it, why would you even need to remove a BB? To route a dropper/brake/derailleur cable? That's a frame designer failure and should be handled in a way that does not require removing a BB. I sold my 2015 Giant Reign with the original GXP pressfit BB after four and a half seasons as it never needed to be removed neither did it fail in that time.

 

TL;DR: don't hate pressfit BBs, hate manufacturer incapability of producing frames in tolerance. If you hate press fit BBs, hate press fit headsets and pressed in pivot bearings with an even greater vigour.

Was actually looking at new pedals this afternoon - I’ve got 2 sets of mallets so like you quite a layout to swap over, but then I aw Silca do Ti cleats.. I’m trying to find an issue with them.. I go through 2 sets a year and I;ve had my current Mallet E for around 5 years, so the Ti cleats would work out cheaper in the long run…
