Any DIY mountain bikers here?

I got a used Trek Wahoo off of Facebook market place and I want to upgrade parts on this bike like the drivetrain and wheels. I?ve searched online and haven?t found any concrete information as how to measure for parts compatibility regarding spacing, hubs and splines. I?m a very mechanically inclined person and would rather DIY than pay someone to do it for me. I went into a local bike shop and asked some basic questions and got the nose up prick treatment. Really put me off on the biking community....

I?d also like some of this info. I?ve been wanting to upgrade my Trek as well but the parts compatibility always has me concerned. I?d hate to spend mine and something not fit.

Have you called/emailed Trek? They should be able to give you compatibility info.

Otherwise, Reddit might be helpful for crowd sourcing info.

My old bike has very little of the original bike left. Mostly just the frame. I did mine a very long time ago though so probably don?t have much to offer at this time. I don?t recall having any issues easily finding upgrade parts that would work.

Google the specs on your bike. Figure out your axle type and diameter. figure out your bottom bracket type. If you know this info you can order most anything. Then get some tools to fit the crap.
I'd toss that Trek and start with a fresh build.

This EXCEPT I wouldn't scrap the Trek. It's a great way to learn the intricacies of bike mechanics. I used to build my own bikes...great enjoyment and pride. There are some tools that are unique to the bike world that you will acquire along the way.

Nowadays

Standard hub spacing is 100mm in front and 142mm rear.

Boost spacing in 110mm front and 148mm rear

There is is extra large hub spacing, i think is it 157mm rear.

I rebuilt my bicycle about eighteen years ago when I was living in Durango. That was before all the information was available online. I was able to find a lot of information in different books and a couple of local shops were more than helpful when it came to looking for parts. It was a lot of fun. Maybe you can use the current "safer at home" situation to contact online sources for parts and advice. I'm not really into the bicycle community but I imagine there are forums out there that have build threads and videos similar to AR-15s and 4 wheel drive vehicles.

Most bike parts are standardized today unless you have some high end boutique $5000 bike. With a Trek pretty much anything on a shelf in a store is going to work.

MTBR.com used to be very good.
