Is it a full bike paint job only, or can we do specific pattern?

I wont speak exactly to Haideli but almost every manufacturer is set up to do this, they just will charge extra. I don't know if he will do custom paint in the group buy.

pending seeing that the large is actually the SC XL (which the chart says it is), then I'm in on a Large/19". Keep in mind that Haideli's large is SC's XL, the m is an L, and the s appears to be an m. If this is confirmed then I am a large. 

Location: BC Canada.

would prefer the bike with a primer only, no paint if possible.

Comparing the geometry of the hightower vs the tallboy, other than wheelbase (1232mm vs 1211mm) nothing is drastically different, generally a couple of mm or less than half a degree.  Do you think this frame could be run with 120mm travel front and rear to mimic the tallboy?  Love the idea of a SC clone but have no need for 140 or 150 travel where I'm at.


You could probably do something like 130/130ish by running a 210x50 shock.  Running a different eye to eye shock is purely speculative and could mess stuff up. If you go shorter than 150mm out front you're going to mess with the numbers too though. Steepen up HTA and STA, lower bottom bracket as well as a couple other things. The rear shock will not change anything really.


I'm guessing that this bike is going to be closer to 150mm out back if it is paired with a 210x55 shock, which is about what actual hightower owners experience when they long shock their bikes.


You can get service centers to swap between 210x55 and 210x52.5. It's not too tough and the hightower likes a custom tune anyway over what most aftermarket shocks come with so don't stress about buying the wrong shock.

Offset bushings don't really work in reverse unfortunately. They have a tendency to rotate to the slacker positioning in short order, so it won't really work for very long.

You can't determine the exact travel when swapping a 42.5 to a 45 because you have to take axle path in to account, and most bikes don't move through their travel relative to shock stroke in a linear manner. So it's kinda unpredictable exactly how much more travel you'll get. You can do a simple approximation but it isn't elegant and won't really get you the answer you want.

The inelegant way is that 45mm is roughly 6% more than 42.5. So that's approximately 127mm of travel. But as I said, that's an approximation and the math will work better for some frames than others.

I would also prefer Haideli or Miracle, but both of those sprung up since I last got a chiner.  Plus the name Tantan is dumb :).


I'm fine to go with whenever they are ready to ship. If that's next week or May, no problem. I've got other bikes to ride.

I don't want flip chips particularly, I'm just curious to see how close they are. The SC links look more refined than the prototype one of these we've seen so far (obviously).  If I end up getting one I'll measure it up and find out some time.


I've heard high end SC bikes are made in china now. I'm not assuming they got their hands on an exact SC and took it apart...but the mold measurements? Maybe.

Same, but no paint for me :P

Edit: I've been out of the chiner game for a while, do these bulk buys at the initial offering usually work out at a discount? If they could confirm the dimensions (which I'm slightly skeptical of) I'd pretty much be OK to pre-order. Maybe something like if we all place our order within a certain timeframe, we can get a certain % off? I don't know.  Either way we should probably not expect much until the new year celebrations are over.

PS - I vote we dub this bike "The Watchtower"

Double Edit: I wonder how close this will mirror the high tower. Will we be able to swap in SC upper and lower links to save weight and add the geometry adjust? Time will tell!

Oh man! My massive, massive, edit didn't save yesterday.

First off, If you've used a negative rise stem full on XC race bike then you'll feel somewhat at home here.

I changed "downsides" to considerations, as for some they will be problematic but you can make adjustments to compensate and solve these but some people will face issues which can't always be assessed right away or riding.

1.  The biggest issue that some will face is that as seat tube angles go beyond 75 degrees or so, there's a chance that some will experience knee issues from increased forward pressure and the reduction of the angle of your legs. It puts more force in to your knees so certain people will experience knee pain. We are going to see more of this over time, as it might not become apparent for a while.  The 'free' solution is to move your seat to the back of the rails, or you can use an offset seat post. Both of these things reduce the steep seat angle and maybe defeat the whole point of the steep seat tube angle. Instead you should swap to shorter cranks if you think this might be an issue or it becomes an issue over time. If you're building frame up, I dont think there's any disadvantage to use 5mm shorter cranks than you would on a traditional bike.

2. you need a longer stroke dropper post to get the same feel as an older style bike. Just a note.

3. Forward hand pressure/arm/shoulder pressure could be a problem for riders that prefer a relaxed fit. This new school geo puts similar forward leans to negative rise XC bikes, but with slight riser bars and stems rather than flat bars and upside down stems. So some less athletic riders will get tired faster or experience hand/arm/shoulder discomfort. This can be remedied with riser bars, shorter stems, riser stems (who uses these on real bikes though?), and in an extreme example, going to a frame size down (which people do to themselves all the time, for better or worse).

As you can see, they can all be dealt with, but if you've never touched a 'new school' bike then they're worth keeping in mind. Most young/apathetic people wont have any issues whatsoever, but if you've had injuries in the past or similar you could run in to problems.

I'm curious if this frame will produce 140mm out back with the stated 210x55 or if it's a direct hightower ripoff (which it looks like) and in fact produces 140mm at 210x52.5? My first chinese bike was stated at 100mm but had closer to 115 out back with the shock size they told me to use.

If you haven't ridden a bike with "modern" upright geometry I suggest you do. The steep seat tube angles make reach feel much shorter (effective reach?) so it doesn't offer a direct comparison to older geometry  bikes. If you have a store nearby pedal something around the parking at least if possible. If not, I wouldn't worry too much if you were already happy on a true cross country fit in an XL before.

The downsides of this modern geometry are:

Could go for a coil shock instead, in which case dialling it in shouldn't be too much of an effort.


Coil shocks have the same options for tuning that air shocks do, minus volume spacers. I've had coil shocks re-valved for my needs.


Moreover I think you'd have a heck of a time fitting a coil in there from the looks of that first picture.

Some Hightower reviews i read mention how Santa Cruz tuned the shock for the new low link VPP. How do you think the performance of this bike will be affected by the lack of specialized tune? Will it feel really different than an actual Hightower?



Many, many bikes get a custom tune over the m/m baseline you'll usually get aftermarket. You end up with a couple options here.

1. Assume its exactly the same as the hightower and order a shock with a tune for a hightower right away (expensive and you have to buy a new shock)
2. Get whatever shock used/aftermarket and then play around with the options available to you until it's "good enough"
3. do #2 but get a custom tune done after you spend some time on the bike.

If you browse the SC hightower thread on MTBR many of them aren't happy with the stock tune anyway.

Eddy says that the geometry chart are correct and confirmed!

I will order a "haideli Size s" because this the same size as the Medium Santa. The other sizes the seat tube would be much longer then original! I think that would happen because haideli use inches for sizing and not "S/M/L/XL"


Hmm weird. I'm still a bit skeptical, not that the L (XL) seat tube at 482 would be too long for me, but I'll probably wait until at least one of the folks on here get something. I'm not exactly in a rush.

Has anyone looked in to confirming the geometry chart? I can see it's lifted from the hightower, but with the sizing offset. It seems weird that they'd choose to produce M-XXL rather than S-XL as their chart shows. I'd strongly consider getting one of these for fun but I'd hate to end up ordering a large expecting an actual XL bike but in reality getting true to size large.

Took her out for her maiden voyage Sunday night- It's good! Still some work to be done before it's ideal. I think the first order of business is a new rear tire, this one sucks hardcore.
