Okay, so I'm shooting for racing Breck Epic in 2025, so if anyone is wondering why I'm posting about XC bikes lately.

Lauf will be releasing a 120/130 XC bike on the 25th, and my guess is that it will have a carbon leaf spring version of Spot's Living Link  https://spotbikes.com/pages/technology 

I have one of their (rigid) gravel bikes, and it's really nice for the money. It'll be interesting to see what they do in the MTB space.

New Hightower release seems like further evidence that we are in a period of only marginal changes for geometry/suspension design. And the trend of "category creep" seems to continue--the Hightower has gone from a 135mm travel bike in Gen 1 to a 150mm travel bike in its new iteration, much like how the Trek Fuel EX or Specialized Stumpjumper have become longer-travel bikes over the years.

Hightower is out now and yet I haven't seen any of the first look articles talk about the new and improved integrated head tube badge, damn it!

The latest Stumpjumper rustled most people's feathers when it launched without routing for mechanical drivetrains. But did you really think that Specialized was that bold? As most suspected (or have seen leaked in this forum), an aluminum Stumpjumper has arrived with holes to stuff a cable. It also has their Genie shock, the same frame layout/kinematics, and geometry package/adjustments. I didn't see much else about the alloy variant that stood out. The coolest thing is that if you are a suspecting buyer, you can now get on the new Stumpjumper for just $3,000, which is $2,500 cheaper than the cheapest carbon model. Build kits and pricing below:

“[O]bliterate every trade-off in the trail game.”

If this kind of ad copy resonates with you, talk with your doctor and find out if Stumpjumper is right for you; “no compromises” is the only 100% accurate FDA approved screening for muppet.

I had a concussion earlier this year and I love the idea of a bike that's so linear they had to make a special air shock being sold with a coil in the top spec.

Stumpy alloy is massively heavier.  Thats a bummer.  Was hoping it would be a 1lb weight penalty, but looks to be almost 4lbs!  S4 carbon weight = 6lb 4oz, where S4 allow = 9lbs 8oz.

What I find confusing about the new Stumpjumpers is they offer it in a coil version with a 27.5 wheel and they've corrected geo for the smaller wheel using the upper link just like with the previous Stumpjumper, which significantly reduces progression. So the most linear bike in the entire lineup comes with a coil.

Only going to correct 1 thing on this statement and that is the geo is corrected for the 160 fork on that version.  They've listed the same geo with 150 on 27 vs 29 rear wheels.

10 mm additional axle to crown usually equates to about 3 mm additional BB height.

As a former SJEvo owner with a real affinity for the brand, I find that entire SJ15 confusing.

I suspect that ridden at 5/ 10ths, in the top spec, it probably feels amazing. However, the STA, the BB height, the CS length, the suspension design in conjunction with a coil shock in some specs, the lack of cable shifter routing in the CF frame...it's just all so far from what I personally want.

The brand peaked in 2021.

The only new bike that truly excites me is the upcoming Sentinel, as I presume, they will get it all correct based on past experiences.

1. The stevo has had a rabid fan base, but we all have cascade links and wrp yokes. This bike will be sick once/if people make some mods for them…
2. Geo is super workable. Worst size is s4 and you can buy an s5/s6 chainstay for it. Cahal is doing just that.
3. I feel like speci is lying by omission here with regards to the stumpy and StEvo. A rep said they were saving the name for something truly Evo worthy. If that’s true, a lot of the criticism that we have for the reg Stumpys could be let go of. If speci puts out an up-market status with a piggyback genie (and maybe more progressive geo? Longer cs, steeper st, etc) I think people would be more chill about how conservative the stumpy is. Of course they aren’t going to launch them at the same time as that would make the regular Stumpys look super boring, so instead we get this (for some) lackluster trickle. Just remember, their lineup is big enough that there is room for the stumpy 15 to be boring

10 mm additional axle to crown usually equates to about 3 mm additional BB height.

Question- The Bronson and Hightower share a front triangle and links(confirmed) but the Bronson has consistantly lower AS throughout the travel. Is this purely because of the lower rear axle height or does the 3mm difference in CS make a difference too?

The pricing should not be surprising but wow... that top AL model is very close to second cheapest NEW CARBON Hightower. Heh... I know what I'm getting.

It seems like 2.5lb is about the average weight penalty for an aluminum frame without the frame being a flimsy soda can.

Adding in frame storage is probably a massive weight penalty too.

I think I called Xfusion for 3k in a previous post, but I also claimed they'd still ruin it with SX and they didn't so... Fair play Spesh.

Still WHY WHY WHY couldn't they sort out base Deluxe or maybe Deluxe S+ shock if it's gonna be 3k. It's the only thing the bike needs. Sigh. Whatever could have been much worse.

Ultimately I think that decision just guaranteed a lot more YT and Canyon and Polygon sales and shit. Could be wrong but I don't think the average rider getting their first FS bike is looking at 3k. Probably 2500 max and ideally 2k. I guess I'd have to compare to Trek and Giant. Maybe this is the new standard. Whether I like it or not...

We get it- you like a progressive bike 😅

I’d think you’d be stoked on this because you get to make another link 🙂

wow... saw that too

And I always thought the RAAW Madonna was portly with its 3.9kg / 8.6lb. 
That thing is so purposefully overbuilt, while the SJ seems quite "normal"?

I don't think the in-frame storage helps on this one

I can't help but feel like the travel creep phenomenon is similar to how trucks keep getting larger and larger bonnets and looking more ridiculous, while the trays slowly shrink at the back. 

Wonder if brands will ever have to do a reset and move the travel back down, or just insert a new name into the 130-140 and eventually the high tower just becomes the DH bike

Building a light and strong and reliable aluminium frame is expensive. Building it 1-2ibs heavier saves on butted tubesets,intricate forgings/cnc and complicated forming,you get less warranties and you still get to charge the same for it.

Marketing guy- More travel is better isn't it? No one buys a bike because of how it climbs anyway......we can just say 'climbs like a 140 bike' and they believe it. And if it does pedal badly we can just sell it with electronic suspension and charge more......win win.

The Madonna weight is without shock.


I’m pretty sure the Stumpy weight is with shock.

That's a burly frameset for sure at 4.31kg . The new Fox Float (195x45) is around 320g so lets say 450g with the Genie mods and bigger size. That could mean this Stumpy alloy frame wo/ shock is about 3.86kg (8.5lb). That is almost the same weight as a Madonna v3 frameset. For comparison a non-sworks Specialized Enduro frameset wo/ shock is 3.45kg (7.65lb).

But that was sans rear shock, so probably still heavier, but as you say, stouter looking than the stumpy

Fun thing is that the 140mm jibb v2 is the same quoted weight. that frame is a closer rival to the specialized

I always felt that the suspension-creep happened for two reasons (and I'm happy to be proven otherwise):

1. Refined kinematics allowing for better pedalling performance allowing greater suspension travel without as many drawbacks

2. Better long-travel single-crown forks allowing for 170-180mm front travel without flexy noodles.

These two combined resulting in models like the Megatower creeping up in travel, and then the Hightower creeps up behind to maintain the gaps in travel from before.

So rather than the mid-travel models getting longer legs, its the long-travel models getting longer and the mid-travel growing to fill the gap. 

As was definitely mentioned: introducing a new model at the bottom of the travel range is probable more marketable, because then all the other models can be marketed as "more capable than last year".

 

To me this progress is feeling a lot like what happened to skis in the PNW, when powder skis kept getting wider so ski designers figured out how to engineer in more torsional stiffness, allowing the super-fat skis to be more capable on not-bottomless-snow, and this made it more possible to increase the widths of mid-fat skis, so then the daily-driver skinny skis also increased in size to fill the gap. Pow skis going to 120+mm waist made mid-fat skis possible at 110+mm so daily-driver skis grew to 100+mm waist.

Sorry for rambly post, this is written between meetings Smile
