Doc's ULTIMATE TORQUE ARMS fit most of the frame UPDATE 2013

[Floont]

Help me out here...

If Doc doesn't get feedback on his design, then how is he to build a better or alternative product (if he so desires)?

I actually like Doc's current design the way it is now and have no desire to have a clamping solution, myself. I bought them from Doc in their current configuration and found that they are quite snug, fit perfectly on my x5404/Mongoose, and they are a great value too!

Still, I feel product evolution commentary is important as is feedback when stated in a positive meaningful way and is healthy even in a sales thread.

The nuance here is that Doc _already_ got the feedback from Aura multiple times in another thread, and _already_ responded multiple times that he had different design criteria. Rehashing it here yet again was the issue.

That said, there are plenty of avenues for giving Doc feedback on his design, from a PM, to a thread using the torque arm, to a new thread you create. Posting on a sales thread would be my last choice, because it isn't relevant to the transaction, plus if there was any good content in the post, it would be LOST when the sales thread is eventually PURGED from the forum, whereas a normal thread would not be deleted.

I love his T-A and only wished he made a pair that was made from 1/4" steel for us sissies running <5kW. Using Nordlock washers ontop of the T-A I just barely can squeeze the nut on to tighten it all up. Perhaps crazy talk as extra stuff just complicates things. Keep up the good work Doc

hey Doc,
do you still have some in stock? i would prefer the tighter ones to fit xlyte 5404 if you have some!

[richirich1113]

Need another set- PM sent

Thanks.

I think i still have one T-A from the last gen that is tighter.. but not the other with the leg..

I have few of the last gen and last batch .. maybe 5-6 set left

How many people are installing these on the outside of the dropout? Wont installing it on the inside screw up the disc spacing etc? Not to mention having to bend my aluminum frame.

If i'm using 52V @ 40Amps should I be ok with just one torque arm on the outside of the disc side?

[el_walto]

Ordered my epoxy from here: http://www.nhsmedia.com/

Came out to $32.47 CAD with shipping and tax. Cost more than the torque arms.

[richirich1113]

Im not sure what their shipping is to Canada but for the US this is the best place i have found.

$27 shipping charge to Canada. Hate stores that do that.

Thanks, definitely looks like the best prices are on ebay. Got to wait for shipping from China though, which usually isn't a problem.

Doc!

Received! Good attention to packaging! This stops the possibility of torque arms breaking the envelope

Doc,
Do you think this is a safe way to hook up your torque arms? I have DP420, but i didnt use it with this application. I have about 50 miles on these torque arms @ 10kw on a 5304 so far. They have not loosened up at all. The hub axle has not spun at all either. The axel is still straight up and down (normally, without the dropouts, my hub axel would spin back to about 2 O'clock. Now it stays at 12 O'clock. I know thats not safe, but i did have about 1500 mile son that setup at 8KW w/o dropouts. stupid, i know.)
I welded a plate to your dropouts so it could be mounted, with hardware, to the bike. i also used a lathe to trim down the thickness of the dropout so my axle bolts could untilize enough threads to fully function. If i didnt lathe down the thickness of the dropout, my axle bolts could only use 1-2 threads. As i ran out of axle threads b/c i added the thick dropouts.

Do you think i need to add DP420?

Gee - that looks pretty slick.
I'll bet your cutting bits were protesting mightily to turn that hard steel....

That's a perfect installation very strong!.. adding the DP420 seems now useless.

Doc

[oatnet]

Great work and ingenuity! That is one beast of a torque arm.

Is the bolt for the torque arm going through a pivot in the rear suspension, or is that a hard tail and you drilled a hole through?

Yea, the bits weren't too happy, but got the job done relatively fast. Thanks!

Okay, then i will leave it as is; without the DP420

Thanks! Im not really sure how to answer that. I guess i would say neither. Its not a hard tail, its a full suspension Kona DH bike. The way the geometry of the suspension is set up, where the bolt goes through is not a pivot point. The pivoting happens above the swingarm, on some additional bracket they built. The pre drilled hole i used, seems to just be where the upper swing arm meets the dropout. It is 100% stationary. All i did was elongate the hardware to accommodate the extra girth from the added bracket. Hope this makes sense.

Bump. I want to order some and Doc needs more interest for another production run.

Tehre is 9 people on the list. I wait to have more to start the production. and i'll need sometime to make them.

Doc

[Thecaptain115]

How many you need to commit? I might buy some extras.

[Doctorbass]

At least to cover the total cost wich is around 15 sets + i need to have the time window to make them...

I never know that i would need to produce 300+ T-A set when i began this project of personal T-A desing set

they are more popular than i thought

Doc

[ecross]

Dear Doc,

I need also one T-A set for my new KMX-Trike.

Best regards
