Echo TR Screw-On

160mm 170mm
Black

Sold out

- ISIS cranks from Echo, forged then CNC'd from high quality aluminium alloy.
- Large recesses machined into the front of the crank to reduce weight as much as possible whilst not compromising strength.
- Comes with a shoulder machined by the freewheel threads to allow more room to fit a bashring without compromising the amount of threads available for your freewheel (Note: Cranks come with a spacer to cover this area should you not wish to use a bashring).
- Fits all ISIS bottom brackets.
- Threaded to accept a front freewheel or screw-on fixed sprocket (standard 1.37" x 24tpi thread).
- Very light yet still stiff and strong enough for street use.
- 160mm or 170mm lengths available, in a range of colours.
- Weight: 460g, (160mm length), 477g (170mm length)
- Offset: 36mm

Any colours not listed are discontinued, Echo now only make these cranks in Black.

Additional Information

Ensure that your pedals are tightened to at least 310 in-lbs (35 Nm) every 5 minutes for the first few rides. Before fitting, it's also a good idea to make sure your pedal axles are clean (a wire brush works well) then greased before installation.
Similarly, always check crank bolt torque is at least 310 in-lbs (35 Nm) every 5 minutes for the first few rides, then each and every ride after that.
Failure to keep your pedals or crank bolts tight as described above is likely damage your cranks and this will not be covered under warranty.

Please note that the minimum required thread contact between crank arm and sprocket/freewheel is 7mm, and a 1.37" sprocket/freewheel with maximum internal thread diameter 33.80mm (NOT 1.375") must be used. Failure to adhere to this instruction will damage the cranks threads and this is not covered under warranty.

Questions

Ryan

Hi, any idea when they'll be available in 160mm Silver? Thanks

Hi Ryan - I believe Echo are only making their TR cranks in Black now, sorry! Almost all of their colours have been dropped from their entire range apart from Black. Thanks, Mark

Zakk

Is there any reason I shouldnt use self extracting crank nolts on these cranks since they are threaded? They are hard to get off my spindle even though they are greased. If not can you recommend something to help me get them off?

Posted by Zakk on 07/01/2013

Reply from TartyBikes on 08/01/2013

Hi Zakk - I can't think of any reason to not use self extracting crank bolts, although my own experiences with self-extracting bolts hasn't been great! Generally speaking, a crank puller should be able to do the job for removing your cranks every time. Most cranks will usually be tight to install, but a crank puller tool removes them in the most effective way from my experience. We've used the IceToolz Crank Puller Tool that we feature on our website in our workshop for the past 5-6 years (and I used one myself prior to that) and they've performed faultlessly. Thanks, Mark

Jonny Robinson

Hi, what is the difference between the sizes? Will they both fit a 20"? And will they fit onza?

Posted by Jonny Robinson on 10/12/2013

Reply from TartyBikes on 11/12/2013

Hi Johnny - thanks for your question. The different lengths simply offer more or less leverage. Both sizes can fit on any size bike, though the usual trend is that 20" riders tend to go for the shorter cranks (160-165mm) and 26" riders usually find the longer cranks (170-175mm) more comfortable. These cranks CAN fit an Onza, though it depends on your bottom bracket. If you have a square taper bottom bracket these will not fit. You require an ISIS bottom bracket for these cranks. Hope that helps. Thanks, Flipp.

Jonny

Will these fit on an onza genesis 20"?

Posted by Jonny on 11/12/2013

Reply from TartyBikes on 12/12/2013

Hi Jonny - thanks for your question. Yes, these will fit that bike just fine. Thanks, Flipp.

david

hello what is the biggest fixed front sprocket i can buy for these cranks or is there arms i can buy to fit a standard 4bolt mountain bike sprocket cheers dave

Posted by david on 03/09/2016

Reply from TartyBikes on 05/09/2016

Hi David - The largest size sprocket you could fit on these cranks that we're aware of would be 22 tooth. The only cranks we stock with the option to use a 4-bolt chainring would be either the Trialtech Race Square Taper Crankset, Onza Armstrong Crankset or the Hope Crankset. Thanks, Mark

Parker Jamison

Will these cranks work well with the Jitsie bottom bracket, the trialtech sport screw on 22 tooth, and the echo urban bashring. I have the 2014 inspired arcade frame. Thanks!

Posted by Parker Jamison on 21/10/2017

Reply from TartyBikes on 23/10/2017

Hi Parker - These should work well together, but the only thing to note is that the Urban bashring is only big enough to cover an 18t sprocket. You'd ideally need something like the Trialtech Sport bashring that's designed to cover up to 23t. Thanks, Mark

Sergey

Hi i have an onza zoot crank on my gu 2014 and its not a good fit the cranck touches the frame when i pedal.. will this crank solve the problem? I also have a onza zoot screwon freewheel do i need to order echo freewheel or it will be ok ?

Posted by Sergey on 08/11/2017

Reply from TartyBikes on 09/11/2017

Hi Sergey - The Echo TR cranks have a lot more offset than the Zoot cranks, so should fit your GU fine. As they're new they'll also be a tighter fit on the splines so shouldn't sit on as far as your Zoot cranks will if they're older/worn. You can remove the freewheel from your Zoot cranks and fit them to this crankset if you'd like. Thanks, Mark

Sweet

Posted by Ant on 24/05/2012

Sweet looking cranks feel very stiff even for me at 200lb.

Reply from TartyBikes on 24/05/2012

Hi Ant - The TR cranks do look great! Thanks for the review.

Very good

Posted by Andrea on 06/06/2012

They work and look pretty good, the fitting on Onza Zoot went smooth.
