This is my new custom mountain bike build. I started with a Specialized Status 140 Alloy frameset in Satin Cast Umber / Raspberry. This bike is unique in that it is a mullet with a 29″ front tire and 27.5″ rear tire. I am running a Fox 34 Factory front fork with 140mm of travel and Fit4 Compression compliments the rear Fox Float X2 shock with140mm of travel. For the drivetrain I am using TRP Trail Evo Gold with TRP Slate brakes and TRP 203mm Brake Rotors front and rear. I am running tubeless on the wheels to help minimize flats, especially while running tire pressure around 22 PSI.

The bike was built primarily for trail riding but will be capable when the terrain decides to get a little rougher and rowdier. I ordered the frame directly from Specialized the first part of July, 2023 and the took my first ride on September 30, 2023.
