Eco Cycles is proud to offer bottom bracket / axle extensions for the TSDZ2. You can purchase these standalone to install yourself (requires tapping your axle shaft with 30*2mm thread) or we will pre-install for the same price with the purchase of any TSDZ2 Model. Perfect for 100mm and 120mm Fat Bikes, or other bikes with 83mm-92mm bottom brackets such as downhill bikes. Simply choose your desired extension length if ordering to D.I.Y., or purchase with any of our TSDZ2 models, and we will install it and ship, ready to go. Extended TSDZ2's are as easy to install as any stock TSDZ2, covered under warranty just the same!
- Available in 92mm, 100mm, and 120mm
- 92mm can be used for 83mm bottom brackets as well
- Includes all required hardware - Extended Bottom Bracket Housing, Axle with extra Bearing and Washer, and Mounting Plate Bolts and Spacers
- Pre-Installed in any TSDZ2 Model Purchase of your choice
- Identical install to 'stock' TSDZ2 Models
- Modified / Extended Motors are still Covered by Eco Cycles Warranty
Extensions come installed in any TSDZ2 purchase of your choice, with all required hardware, as outlined above. Example photos show models with protective covers, as well as chain guides - both of which we offer - separately (chain guides and protective covers are not compatible together without modifying the protective cover with a slot for the chain guide to protrude through. Motors and other accessories in pictures are shown for reference only.
We also stock BB Spacers which may be needed for a solid installation, as seen in the last picture, and noted below.
NOTE: As seen in the last picture, 3" / 76mm of clearance is required from the center of your BB, directly over to the chainstay - otherwise installation will be obstructed. Depending on the depth of engagement, you may be able to just shim the BB with some spacers, although you may also have to go an extension size up/longer in order for the thread to protrude on the non-drive side. Don't worry, if you order the wrong size and it does not work, we will exchange it with an appropriate size, and installation is as simple as removing a lock/clip ring, and unscrewing the extension.
