Building a hardtail mountain bike (WiP)

Most of the time when I go on a bike ride I ride off road on trails and sometimes even on downhill tracks. For that purpose i found a bike which fits me perfectly and is a lot of fun to drive: the Yeti SB5.5. I absolutely love it. It is a very heavy and big machine though and just to expensive to use a “drive everywhere” daily business bike so i decided to build up a hardtail mtb i can use for light trails, driving to work and longer tours. This will not be a detailed post. just a small build log.

Finding the right parts

Big spreadsheet of possible parts and combinations with specs, comments and url’s.

I started with looking for a frame which fits my needs in geometry and style. There are a lot of different options and i settled on a Dartmoor Primal 29 from a small but very good looking Polish company. After choosing the frame i narrowed down the options of the rest of the parts. A lot of things depend on the frame, eg. headtube size for the fork or wheel size. After all i got these main parts:
– Dartmoor Primal 29 XL frame
– FOX Float 34 Rythm 130mm Fork
– Shimano SLX 1×11 gearset
– Shimano Deore breaks with 160mm back and 180 mm front discs
– Falcrum Red Zone 7 wheels Tubeless with Schwalbe Nobby Nic and Racing Ralph tires
– KCNC IS42/28,6 – IS52/40 headset with Race Face XC stem


I started with the front of the bike. Fitting the headset in was really easy because IS headsets do not need to be pressed in. Just put in the bearings, add the crown to the fork, put everything in and retain it with the stem.

After that i installed the breaks which was, also, pretty easy. Just add the adapters to the mounts (for the right break disc size and mount type), screw it together and that’s it.
