Nice...

Did you order powdercoat or anodized? Oh, and who did you order from. Just curious since I have a frame on order through Cambria.

VP-Free Chainline Caution

I've got a VPF on order but I'm having second thoughts. I can't seem to pin down a good chainline solution. I've had two threads going with Santa Cruz and RaceFace and neither thread has resulted in a good solution for me. The SC thread is first below, followed by the RF. If anyone has a good suggestions for heavy duty cranks that will work on the VPFree. let me know. I'm not wild about the ones SC is suggesting.

Santa Cruz thread:

----------------------------

I've never tried running the Diabolus cranks so I do not have solid
feedback
for you there, but the VP-Free's optimal chainline measurement is 55mm.
This
means that you would want a measurement of 55mm from the center of the
BB
shell to the center of the chainring set-up you run.
With a tripple ring used, this would be measured from the center of the
BB
to the centerline of the middle chainring.

In our kits with a Single Ring and Chainguide, we use a 73x128 ISIS BB
and
ISIS cranks and a E13 guide.

You may want to contact RF direct to see if Diabolus cranks have a BB
spindle option long enough to work with the 55mm chainline standard.

Thanks again, and let me know if you have any other questions.

The 3mm adjustment allows your chainline to be adjusted from 48-50mm.

Would your "3mm of adjustability" be enough to make
the Diabolus work on the VP-Free?

Well...

I saw your post here about the issue and emailed Scott Turner and got the same response as you did about the 55mm optimal chainline for the VP-Free. I am running the Diabolus cranks on a Bullit now and I think that they will work for the VP-Free (I plan to use them on mine when it shows up). I'm not sure what to say about the RF reply that you only have a 3mm chainline adjustment (48-50mm is only 2mm of adujsment anyway). The instructions that came with the crank say it has 6mm of adjustment, this seems to match the fact that there a six 1mm shims (2 black & 4 white) on the non-drive side at the 48mm setting. It could be that the 3mm adjusment (the instructions give specific information on the 48-50mm settings) are good for "any" frame where the other 4mm's are only do-able on a frame-by-frame basis (i.e. do the crank arms clear the frame).

As for reaching the 55mm optimal chainline? You may not want to get too worked up about it, it's not like you are doomed if it's not 55mm. If you are on the short side on chainline the worst it will do is keep you from using the smallest cog or two, it depends on how far off you are. For me, I hardly ever use the 12T so losing it would not be a big deal.

FYI, I run a single chainring with a chainguide.

Looks like Santa Cruz got their april release date....just ;)

I ordered from Cambria too.

PattD, when did you place your order?
Looks like you are in luck also! PattD

chainline...

I had the same chainline issue when I tried to decide which cranks I would choose to my V10. After checking for specs for X-type Diabolus cranks and ISIS North Shores(BB with 128mm spindle) I ended up to get North Shores. Better to get right chainline and shift smoothly :)

I hope RaceFace would release X-type version of Diabolus cranks with longer spindle that equals 128mm ISIS spindle and have the same chainline adjustments. Current Diabolus spindle seems to provide almost same chainline adjustments than 68/73 BB with 118mm ISIS spindle.

Note that there also might be crank arm clearance issues with too narrow spindle on VP-free.

update on RF chainline capability

[Hi Rob,

Compatibility update, unfortunately you were the recipient of some
outdated
info, sorry about that. Although we're not 100% certain of the
clearance on
the VP-Free you will be able to obtain a 54mm chain line with the
Diabolus
set-up. That should be close enough to work with the VP-Free. Thanks.

cheers,

Much better...

It's good to see them working with the updated information, what they originally sent you just did not sound right (it is a new product). Also saw this article that might give you comfort:

http://www.nsmb.com/gear/diaboluscranks_04_04.php

Because of the unusual chainring/chainguide setup he only needed to run to like 52 or 53mm on the chainline.

So, did you get the frame yet?

Come on, give us some pics :D

I need to see something to give me hope for mine ;)
Will try and post pics tonight at home. It's sooooo sweet though!

How are they working for you? How long have you had them?

I killed my cranks at Whistler on Saturday, so need to replace them. (Pedal threads stripped out of non-drive crank.) I've been going through RF Signature Isis FR BB bearings in less than a year so maybe it is time to change to something else.

Has anybody had any luck with this combo yet? Any pics of it in operation?

The above reply from Scott at Santa Cruz is the EXACT one that he gave me with my same question on the subject. It looks like he just did a cut and paste of when he answered you and the answered me with the same.

Attached is my original question and replies from Santa Cruz, Race Face and EVIL/e-thirteen.

My original question:

Santa Cruz Reply:

We have not actually tried to run a set, but it looks like the Race Face
X-Type/Diabolus cranks will not work correctly with the VP-Free, due to
chainline adjustment issues.
In the Diabolus installation instructions it states that you cannot use the
spacers to adjust chainline with 73mm BB shell widths, which is what you
would need to do to get correct chainline with the VP-Free.
You can run Race Face ISIS Drive cranks.

The VP-Free's optimal chainline measurement is 55mm.
This means that you would want a measurement of 55mm from the center of the
BB shell to the center of the chainring set-up you run. With a single ring
used, this would be measured from the center of the BB to the centerline of
the single chainring.

For multiple chain ring/front derailleur use the best set-up will be a
Shimano e-type with our custom e-type clamp/locator and custom TruVativ BB
for the VP-Free (This is shown in one of the pics on the MTBR link you sent
me) This set-up will come in our VP-Free build kits with a TruVativ
Holzfeller Double 22/32 w/ rock guard.

If you are not getting the kit from us, you can order the clamp for an
e-type derailleur and the custom BB from us for use with ISIS drive cranks.
Just have your dealer order it with your frame.

If you want to run a Double or Triple chain ring set-up and a clamp type
front derailleur, use a 34.9 Top Pull/Top Swing and a 73x128mm BB. This will
give you the best performance possible with a clamp type derailleur, but not
as optimal as the above mentioned set-up (e-type) that gets around the
inherent problems with front derailleurs and long travel bikes.

With a Single Ring and Chainguide, we use a 73x128 ISIS BB and ISIS cranks
and a E13 guide. Other Chainguides (MRP, etc) should work as well.

All pretty confusing, but until component manufacturers (ie Shimano) come up
with a new front derailleur design with more rotation for longer travel
bikes, and a crank/bb standard to work with the 150mmx12mm standard
hubs/chainline, we'll have to keep designing work-arounds.

Thanks for choosing Santa Cruz, and let me know if you have any other
questions.

RaceFace Reply:

There are a couple of points here that need 'clarification'. First the Diabolus chainline can be adjusted with a 73mm BB shell. BB shell size and spacers HAVE NO AFFECT ON CHAINLINE. Secondly, the Diabolus crankset has a chainline adjustment range of 48mm to 54mm, plenty wide enough for a 150mm rear hub. The Diabolus crankset is also E-Type compatible, however the issue with Shimano derailleurs not having enough rotational adjustment will still be an issue at the widest chainlines if you want to run a triple ring setup. The primary issue with setting up Diabolus cranks on a VP Free is non-drive crank clearance. With the chainline at it's wideset, the non-drive crank will be closer to the frame and there is the possibility that the crank will interfere with the chainstays or the suspension pivots. We have not been able to install Diabolus crankset on a VP Free, so we cannot say for certain whether it will work or not.

Thanks for your email.

cheers,

You should be all set. The cranks will fit fine. If you do run into any issues that I haven't foreseen please feel free to get back in touch.

Also, if nobody has any luck, I am hoping that the guys at Speedgoat can answer some questions. They are doing a step by step build on the VP-Free which is very cool and their next step is installing X-drive Diabolus cranks.

I am hoping that they do not run into the problems mentioned in this thread and give up to install a typical ISIS drive or something because they know it will work easier. I sent them an e-mail expressing my interest in the follow through with the Diabolus and I encourage others here to do the same so we can be sure that they know that many people are interested in this.

Here is the link to the build up:
