2021 GT Brian Kachinsky BK Team

When Brian Kachinsky signed up for GT he was immediately handed a signature range of bikes to help design and build. The BK line of signature bikes is the result and it starts with this, the Team model at just £399: for a hair under found hundred quid you’re getting a trimoly frame with a 20.75″ toptube, a super-short 13.2″ back end, downtube gusset, 75º head angle, and all the geo street-smarts you come to expect from Kachinsky and GT. This thing rides SO good.
Factor in the Chromoly GT fork, legit GT OG 4pc bars, GT supersoft grips, topload GT stem, proper 3pc Chromoly cranks with 170mm arms, PC pedals, and GT’s ever-popular 2.3″ Pool tire – a personal favorite of Brian… which is why he specced them on this bike.
Custom graphics featuring the Chicago metro map (BK’s hometown) really set this thing apart – which matches the signature pivotal GT BK saddle. For £399, this thing is dialed… and finished in new all hammerite black, you can’t go wrong.
