A couple guys say they've done it on that one. Alpha Platinum Aluminum, Boost148, Midstay, tapered head tube, internal derailleur & dropper post. Here's a video of someone who did a BBSHD on a Dicks Sporting Goods Raised chainstay bike. A 3 speed Sturmey Archer IGH will make it stronger and simplify chainline and chainring size selection.The raised chainstay does make a belt drive Alfine 8 speed IGH a possibilty. Here are the specs: Frame - Alpha Platinum Aluminum, Boost148, Midstay, tapered. Size is Medium, and the color is Cobra Red. The hard part for you may be getting it to go slow enough to ride in the woods. I have a used, but in good condition, 2019 Trek Stache 7 for sale. But it will probably be easier if you can run a 42t ring. How wide is the rear hub on that? I've personally only built a couple of older 26" TrekGF 26" bikes so others may know more than I do. Treks traditionally used a 73mm bottom bracket width. Can a 42t ring clear the chainstay in all gears? I would try that first. Quality parts and regular maintainence and repalcement will be required. Chainrings smaller than 42T need to go outside the motor and may not be able to use the lower cogs. You need to investigate the chainline issue. Thanks in advance for any help you share! I just don't want to tear into my beautiful Stache 7 (The Green Goblin) only to find out the systems just don't work good together and have weaknesses that could leave me broken down in the woods. I am very good at bike mechanics and have plenty of tools and power equipment, so the technical side doesn't scare me. Size: M/L (18.5 inches, for rider 5'5' to 5'10' or 165cm to 179cm inseam: 30.3' to 33.1') Color: Matte Cobra Blood. What chainring size would be best for a BBSHD? Is the Trek unique raised chainstay an issue, or is it a benefit? Specifically, is the 11-speed chain too weak and narrow to handle the BBSHD power? It seems the narrow 11/12 speed chains are often mentioned as not as strong as 10sp or 9sp chains. Looking at the specs and pic attached, is there anything you see that would make this bike NOT a good candidate for a Bafang BBSHD kit, like the kit Luna sells?
So I have some questions I am hoping I could have answered or given advice on. I really like the upgrades I have done on this bike, but I am also smitten with eBike technology and capability, especially in my very hilly and mountainous Virginia location.

This bike has been discontinued by Trek, so they are difficult to find.Īsking $1900 or best offer. Specs are pretty much stock, except for an upgraded GX rear derailleur.
I recently purchased a Trek 1120, which is specifically for bikepacking, so I'm selling this one. This is such a fun hardtail to ride, with monster 29 x 3 tires, a raised super short chainstay, and a 120mm fork, and it can handle more technical trails than you realize. The scratches on the fork are on the lowers, the stanchions are in good condition and the fork works perfectly. It's in good condition, but it does have some superficial scratches on the frame and fork. I have a used, but in good condition, 2019 Trek Stache 7 for sale.
