I wanted to build a titanium snow bike capable of running 4.7″ Surly BFL or Husker Du 4.0, so here it is:
Behold, the Carver O’Beast Ti Snow Bike. I tried on this build to feature parts from smaller and/or lesser know companies that build fine products, and I think I have a good mix here.
Probably not the best year to build a new snow bike with the lack of snow in almost every state this year, but I did get it out a few times so far. The beauty of this symmetrical 170/135mm build is that I can have a second set of wheels for the Spring/Summer without some of the issues of building offset wheels.

NOTES: As far as the build went, I seem to work on so few “normal” bikes this was relatively routine whatever that means anymore.
The bottom bracket threads were wrapped in PTFE tape before greasing the threads and torquing. Creak-free longer this way.
The front fork is crazy light. Surprisingly, the supplied shim washers for the rotor worked perfectly. Typically, screwing around with spacer washers is exceedingly time-consuming.
Shifting went together perfectly! It’s key to run the front derailleur slightly higher than optimum on a “normal” bike. Correct set up involves getting the FD’s inner cage to just clear the outer chainring on upshifts. Insuring that the tail of the FD clears the top of the chainstay is also necessary.
The brakes were easier to set up on your Carver than on the Moonlander. –it’s possible to actually see the pad to rotor clearance on the Carver. On the Moonlander, if the tires are installed, it’s all by ear.
