Giant Stance 2 with BBSHD and 52v Shark Pack

[Rodney64]

Best to try, Whats your inseam

[pcliteuser]

i saw this model on a local bike shop here and i noticed that the medium frame is a bit small though they don't have large & XL size for me to test fit. i'm 5'7 may i ask if its posible to stand over large / XL giant stance frame comfortably?

Just a follow up (I posted this in my build thread) but the Amazon adapter posted above does not work. For two reasons actually. The ends are too big (unless you lath them down) and the inner diameter of the center section is too large (big gap between the outer diameter of the BBSHD and the inner diameter of the adapter)

[samholton]

Got confirmation from Luna its the 73-100mm

[samholton]

Hmm maybe not the extra fat. Need to get the bike :)

[samholton]

One more question, when you say the 100mm BBSHD are you referring to the 73-100mm (Fat) or the 100-120mm (Extra Fat)? I'm guessing the extra fat with the two additional biting spacers?

[samholton]

The 2016 has the 11x34 and the 2017 has 12x36

[samholton]

Wider range isn't on my list and I don't think I'd need 34 let alone 36. Will have to compare the 2 and see if it's worth getting 2017 and thinking about changing cassette later to get that 11t. Only other thing I remember being different are the brakes ana maybe the derailleur

I've made a few little changes to my 2016 Stance and have some more plans. A wider range of gears isn't on the list. I haven't come anywhere close to amping out the BBSHD (30 Amps) in my 34t cog. I suspect I'd just burn rubber in a tractor-pull contest. (I only weigh 145lbs.) Speed is good... And more speed is better. Hmmmmm. All things being equal, especially the price, I would probably want the 2017, with that 11t cog.

[samholton]

Oh, any suggestion regarding 2016 Stance 2 vs 2017 Stance 2? I noticed they switched the cassette from an 11x34 (in 2016) to 12x36 (in 2017). My LBS is offering discounts on 2016 so I can get them for pretty much the same price. I'm not planning on any large hills and realistically don't need top end speed (but sure I'll want it). My back of the envelope calcs show only a few MPH between 11 and 12 with the 42T up front.

Just noticed this reply. I ordered 2 sets (just in case my wife goes the Embolden route) of the China bracket. I have read your build thread a few times and one of the reasons I'm leaning towards the Stance. Seems like I should have a much easier build on my hands. The 5-6 week shipping time may come into play once I pull the trigger and order the bike and BBSHD/battery. If it does, I may reach out to you about your bracket and then pay it forward with the two I have on order.

Unless Eric/Luna can hook me up with their custom bracket, will be buying two BBSHD and batteries after all ;)

Thanks, Eric. My Editing option is back!

[Eric Luna]

you should have ability now to edit your build thread :) try now.

[Eric Luna]

hi bones...why can you edit your own build thread? pm me and we will try to fix this.....

[Bones]

Any update on the full build guide? Thinking of pulling the trigger on this build. I'm interested if this adapter from another thread (http://www.ebay.com/itm/301825746922) is actually the correct one? Also, the biting spacers (cut from the Y brackets) I need to order 2 additional? One comes with the BBSHD kit (unmodified) and I'll order two additional which I cut. Or do I need 4 (2 on each side). Thanks!

I lost the ability to edit my Build Thread a few weeks ago, and I have some concluding remarks to make on the best way to go with the bottom bracket adapter. Since samholton is ready to get after it, I'll just do it right here. By the way, this is an incredible bike. My son just took it for a spin along Alki in West Seattle (wet roads, twilight). First time on an E-Bike. He's back in 15 minutes absolutely ECSTATIC. (He went straight to PAS 9 and 9th gear: ~30 mph, pedaling like a maniacal cyborg.) He no longer wants a Tesla. Go for it Sam.

First the easy answer. No spacers of any kind are to be used on the Drive side (it will screw-up the chain-line), so you need two additional, modified Y-Brackets, to make two biting spacers for the non-drive side.

I know of 3 ways to go about this, avoiding the lathe modification I did for my build.

BB30 to BSA Adapter (photo in Eric's comments, above):
The adapter is slightly dogbone shaped. The 41+mm CENTER of the adapter is what is valuable. The two BB30, 42 mm ends should be cut off and discarded. Cut the center section in half and you now have the bushings you need. Use Loctite and press them in flush with the bottom bracket shell. These parts are just bushings, so the cuts don't have to be perfectly square. Make sure the BBSHD and biting spacers make full contact with the Stance bottom bracket shell (not aluminum bushing sticking out.) The one problem with this plan is that the critical tolerance for this part is the two 42mm BB30 ends, not the turned-down center that we use. My adapter's center section was a decent press fit, and would be fine with Loctite. If you end up with an adapter with less than a 41mm center section, you can't complain to the adapter supplier.

China BB92 to BSA Adapter:
I've got one set, and I don't have any use for them. They look nice. PM me if you want them. My caliper battery is dead, so I can't see how much over 41 mm they are. If I used these on a build, I would grind off the "end flanges", so the adapter could be pressed completely into the Stance shell. The flange on the Drive side is detrimental to your chain-line. The flange on either side has the BBSHD biting into the adapter, not the Stance bottom bracket shell like it should. That puts a twisting moment on the adapter. It might slip in its bore. A 20 minute session at a bench grinder and we don't have to test this.

Talk Luna into Selling you Their Custom Adapter:
This is my favorite solution!!! With this and the simple mod on the Y-Brackets to make biting spacers, you have a very simple build.

Have fun!
