Description

The Griffin 24 is designed as a pumptrack and dirt jumper hybrid, and it is in a league of its own. The frame is 6061-T6 aluminium with a tapered head tube and a forged yoke, and up front there is a Manitou Junit Circus Comp fork with 90mm of travel.

The rest of the build is set up to be ridden hard from the first session down at the local: Salt+ Ultra 3-piece BMX cranks, front and rear disc brakes, double wall Arise DB32 rims and Kenda Small Block 8 2.1" tyres, finished with a Radio Century combo seat.

Features
  • Dirt jump and pumptrack hybrid. A 24" bike designed to handle jumps and carry speed around a pumptrack, so one bike covers both.
  • Manitou Junit Circus Comp fork. 90mm of travel up front takes the edge off rough lips and hard landings.
  • 6061-T6 aluminium frame. A tapered head tube stiffens the front end and a forged yoke tidies up the rear, keeping the weight down.
  • Front and rear disc brakes. Tektro Aries mechanical up front and an HD-M275 hydraulic at the rear, both on 160mm rotors for consistent braking.
  • BMX cranks, dirt jump wheels. Salt+ Ultra 3-piece chromoly 140mm cranks, sealed Radio PRO-DJ disc hubs and double wall Arise DB32 rims on Kenda Small Block 8 tyres.

Assembly information

Your bike ships mostly assembled in the box. Finishing it takes most people 10 to 20 minutes with basic tools, and the video above walks through every step.

  • Fit the handlebars and line them up with the front wheel
  • Fit the front wheel, pedals and seat post
  • Check the brakes and tyre pressure before the first ride

Tools: Allen key set and a 15mm, 17mm or 19mm spanner for the pedals and axle nuts (bikes can vary between these three sizes). A socket is needed if installing pegs.

Rather have it done? Ask us about extra assembly before you order, or any local bike shop can finish the build for a small fee.

24 inch BMX sizing

A 24 inch cruiser is a BMX with a bigger wheel, for riders about 160cm and up, on a 21.75 to 22 inch top tube. It is a different ride feel rather than a bigger frame for taller riders.

Rider heightWheel sizeTop tube
60 to 91cm12"12 to 12.5"
81 to 106cm14"14 to 14.5"
96 to 122cm16"16 to 16.5"
122 to 147cm18"18 to 18.5"
147 to 157cm20"19.75 to 20.25"
157 to 168cm20"20 to 20.5"
168 to 175cm20"20.25 to 20.75"
175 to 183cm20"20.5 to 21"
183 to 190cm and up20"20.75 to 21.5"
160cm and up22"21 to 22.25"
160cm and up24"21.75 to 22"
160cm and up26"22 to 23"

Sizes overlap on purpose, so personal preference comes into it. A big wheel rides longer than its top tube number suggests, so do not compare it straight against a 20 inch. Race cruisers are sized differently again: see the race guide.

How to measure

Stand against a wall in the shoes you ride in, heels flat, and mark the top of your head. Measure from the floor to the mark.

  • Choose a big wheel for the ride feel, not because you are tall. Plenty of tall riders stay on 20 inch.
  • Coming off a 20 inch? Expect it to feel longer and more stable, and slower to spin.

Not sure? Tell us your height and how you ride, and we will tell you what we would put you on.
