Norco Bigfoot VLT 1 running plus size

Hey guys, I just wanted to document my experience with this conversion and a few tips.

In December, motivated by [Ride Year Round](https://www.youtube.com/c/RideYearRound), I decided to get a wheelset to run plus tires but different from his setups I decided to go for 27.5+ just for fun (and because I already had tires and cushcore for it). So I started to check geo and noticed going from 26×4.6 to 27.5×2.8 would only lower the rear end by 10mm, can be problematic in some frames but seems to be within spec for this frame and it’s similar size to 26×4.0, so great success so far.

Got a pair or RSD wheel built with Duroc 50s and SRC FB hubs (they actually ship this in some of their fatbike to run 27.5×4.0) and encountered the first difficulty, cushcore in plus sizes is more of a pain than regular sizes but nothing some crushed fingers and a messed up tire lever couldn’t solve.

With tires, inserts, rotors and cassete mounted, I found a problem that took me a while to find a solution, due to the rim being slimmer the spokes are disposed further away from the speed sensor, which causes errors and the bike virtually gives you no assistance. So after scratching my head for a couple weeks, I decided to buy a [bosch spoke magnet](https://www.ebay.ca/itm/175067253169?_trkparms=amclksrc%3DITM%26aid%3D777008%26algo%3DPERSONAL.TOPIC%26ao%3D1%26asc%3D20230811123856%26meid%3Da277a63e33da471cac8e93ed6fd48b30%26pid%3D101770%26rk%3D1%26rkt%3D1%26itm%3D175067253169%26pmt%3D1%26noa%3D1%26pg%3D4375194%26algv%3DRecentlyViewedItemsV2%26brand%3DBosch&_trksid=p4375194.c101770.m146925&_trkparms=parentrq%3Ace94d8bb18e0ab9d6d5afcbafffef060%7Cpageci%3Aa9e4ae1b-f837-11ee-b3e2-666d1b4e292f%7Ciid%3A1%7Cvlpname%3Avlp_homepage), which to my surprise, wasn’t long enough (about 20mm away from the sensor) and not within spec for the sensor (6mm-15mm away if I remember right).

So after fidgeting and further scratching my head, I noticed the pins from crank brothers pedals fit and are exact same thread as the previous sensor, but with a little caveat, they are longer than stock screw. This sparked the idea for the solution, screw two sensors together using the pins to make the length! It’s by far not an elegant solution, but 100% functional and practical.

Again this is just documenting my experiment, I don’t recommend doing it and really not sure if Norco would warranty a frame that runs like this, but here is one of the most niche problems I found also would appreciate if you found different solution for this problem.
