Appreciate it!

Yeah so the titanium bike I actually built as part of a college class. It is called hand built bicycle at the University of Iowa and is only about 10-12 students and you build a bicycle frame from scratch. I received engineering credits for completing the courses. The first time you build a chromoly steel frame to make sure you get the jist of frame building down. The second time taking the course you are allowed as much freedom as you wish to create your titanium masterpiece. I began designing on autocad basing some of the dimensions off of a salsa deadwood, the hardtail version, which is a 29+ bike packing rig. Other dimensions I adjusting using my personal body geometry and what ive learned from my previous experience with my chromoly frame. Once everything is in place ordered all the ti tubing and titanium machined parts and set up the frame jigs using the dimensions from autocad. then tube by tube cut them to length and notch the ends with a whole saw and hand file till each is a desired fit. then when the front triangle is complete tack it together and begin the rear triangle. I used a flex plate to allow the rear triangle to flex under larger loads and act as a small suspension dampener.

I’m with you. I think it’s that in the US, those who sell them and those who buy them seem to have complete lack of regard to keeping trails open for MTB use. Also the ridiculousness of how they keep trying to justify why they should be on non motorized trails.

I'm always amazed at just how much I look like a total shitbag.

Beat old 2012 Morewood. Still strong. Still solid.

Most here in the netherlands is flat, so a hardtail XC is fine.

This thread makes me want a new bike. I'd like to keep my 2013 Cannondale scalpel, and get one of the all-mountain style bikes to ride some more of the downhill style trail systems NJ has to offer.

This is an old thread. I'm sure somebody has a new bike. Lots of Mtb rides going on lately and not that much moto around here. I think my buddies and I ride Mtbs three times more than moto lately. Let's see some new bikes!

This is my Santa Cruz Chamelon that I’ve been building the last few years I love it but wish I had the full squisher sometimes. Two strokes and hard tail bicycles I guess I’m a glutton for punishment haha

If you ride MTB, sure, you're cool. But are you "design and build your own titanium frame" cool? Wow, I'm impressed with Chase.

+1 for the aggressive hardtail. I have a BMX background so the full squish never felt right to me, ht has never limited me. Here is my 2020 Marin San Quentin

I have the oneup dropper, great value for the money and it goes to 200mm. It also has a low stack height to really slam the seat down. Between that and a cushcore a hardtail is where its at!
