I can't imagine what toe overlap would be like for a 32" gravel bike.  My giant revolt with 48c tires is already precarious enough.  Come to think of it, do you end up with toe overlap on a 32" xc bike with a 68 degree hta with reaches under 450-470?

Bike brands: You don't need to tool and produce 27.5" lowers anymore, the market wants mullet and full 29" bikes.

Fork makers: Phew, what a relief. Between wheelsize, offset, and axle sizes, it's a lot of parts to manage.

Bike brands: What have you got in the works for 32"?

Fork makers: Excuse me?

The bike industry is its own worst enemy. Nothing wrong with 32" wheels, however it should recognized as a niche offering. Any tire, rim, fork maker, etc should get a contract in place before designing and opening tooling for a 32" project with a frame brand.

If the niche for 32" wheels is people over 6'6" tall, it's hard to make a business case for making them.

If the niche for 26" wheels is people under 5'6" tall, that's much easier to justify because not only are there grown adults under 5'6" tall, every adult who is over 5'6", was at some time under 5'6".

32" is clearly too large. 29", on the other hand, might not be large enough. So obviously the future is going to be 30.5" wheels.

Having tons of stock and about to blow the F out of everything old in about a month. They've had $3800 CAD Slash 9.8s for months now and keep releasing new batches of crazy sale bikes.  Get ready for 40-60% off sales of all that previous gen stuff. 

I also don't get that Slash 5 limited edition flight attendant build and new colour. Who's really shelling out 10k CAD for a generation old bike when 10k CAD gets you a great new one? 

I hope they have discounts this side of the pond as well.

I originally looked at getting a Trek like 18 months ago. But was told there was NO WAY I was getting a discount, and delivery times were 3-4 months. Went to the other side of town to a specialized shop, got a smoking deal on top of an already discounted msrp, and had the bike the next week. So not a huge fan of Trek here.

“Im sorry did you say niche? Im (big bike company name here) and I see this as a perfect opportunity to convince you, that you need 32” wheels or you suck at riding. Im going to milk this cow till its dead. You say it works best for 6’ 5” tall people? Im sorry but, wrong, it is the next best thing for 5’ 6” tall people. Tell me otherwise and our lawyers will be at your doorstep with a bat. Keep the rubber side down or some shit.” - Scott Bikes probably.

I see your size-specific chainstay lengths and raise you – size-specific wheelsizes! 24" XS, 26" S, 27.5" M, 29" L, and 32" XL.

Bring 27.5 back for the 1SD around the mean.

The large suspension manufacturers have stopped making 27.5 forks in XC and DC applications (SID, 34, etc). I assume the volumes were too low to support 2 wheel sizes for what are categories that prioritize efficiency, meaning larger wheels. I could see this being a thing in more categories. I would hazard a guess that the industry-wide split in high end bike design, including size range per model, is 90-10 in favour of 29er.

The clear solution is that we all need inverted forks with swappable crowns. That way you can use the same, noodly, 6 pound fork for for DownCountry, Trail, All Mountain, Enduro, Super Enduro, Freeride (its not dead!), and DH racing! As well as anything from 24" to 32" front wheel sizing!

Pair it to that new Vampire bikes that has a 50mm+ swing in different travel lengths! 

I see no downsides, certainly not in weight, tuned stiffness, nor geometry.

Yeah I am not sure what Trek is doing. They are still offering like 5 different full bikes, and 5-6 framesets from last gen Slash as well. And the new gen slash has been out for more than a year.

They also "re-released" the Slash 5 with a new colorway fairly recently. Do they just have that many unpainted frames left in stock? Still they want full price for them.

 

The fact trek has not aggressively discounted their stock at any point has been an interesting business decision.  When the new slash was released I went to trek to see if there was a deal on the old one and at the time they were still asking full price.  I think the largest discount I’ve seen on their bikes has been around 25 percent on really old models.  Compared to their number one competitor (spec) who seemed to at one point have anything that wasn’t axs on a near 50 percent discount.  Meanwhile there are rumors of huge numbers of trek bikes just sitting in warehouses.


Now I could understand tld or fox being pretty protective of their perceived value even at the risk of losing revenue in the short term.  But when it comes to bikes isn’t the hardest thing to accomplish is to get a customer to actually get on one?  And if there are just way better deals available how do you expect to do that?  

I really enjoyed the trek I owned.  The lbs I bought it from was great.  The bike was good.  It’s the only bike I regret selling.  But hell the only reason I got it was because it was on a discount.  

The lbs (diffirent one I’ve moved) I support is a trek dealer.  I really like every experience I’ve had on a trek bike.  But I’m not going to rush to replace my perfectly good bike with slightly better trek when there are way better priced options available.  And short of another pandemic I don’t see how trek expects the market to recover where they can ask good money for an old model.

Perhaps I'm naive (or just spend too much time here) but not having an X0-level mechanical Transmission ofering seems like a miss; existing NX/SX bits are such poor quality that I feel like it'll turn people off (and misses the market segment that wants high-quality mechanical shifting, or pushes them to Shimano).

it'll come, They needed to get the high end consumer to early adopt, and buy into the world of 1's and 0's, cause that would cover the investment costs.  

Then the GX beepboop came out to gather up the rest of the money.

I'd wager we see an XO lvl mechanical transmission groupset come out in early 26

Seems like they're focused on huge market of low price OE offerings, not stuff for us.

The thing about 29ers is frame designers are still dealing with fitment issues, 20 years on. This is why we've seen all these various chainline, axle, hub standards proliferate, not mention endless conversations around geometry. Paul Aston seems to be fine with 475mm rear centers but any good (technical) trail that I've ridden around the world plain doesn't work with titanic sized wheelbases.  

Last but not least, and understandably this the same argument some have with ebikes and we can see how many of those are on the trails now, I don't need bigger wheels to make things easier. The pendulum swung far enough with 29x3 and we all saw how that worked out for MTB (Desert touring setups disregard this comment).

I can't imagine what toe overlap would be like for a 32" gravel bike.  My giant revolt with 48c tires is already precarious enough.  Come to think of it, do you end up with toe overlap on a 32" xc bike with a 68 degree hta with reaches under 450-470?  

What stem length are you running on the Giant?
