Description

French brand Inspyre have been quietly producing bikes for the past few years and have established themselves as a respected manufacturer of complete race bikes. The 2022 Inspyre EVO Junior Disc Brake Bike comes equipped with all the components that you need to take this bike from the shop to the track, and on to the podium. Out of the box, the Inspyre features a 6061-T61 hydroformed triple-butted tubed aluminium frame, with additional highlights including a set of Forward Joyride cranks and Forward Joyride hubs, with the rear hub having 150 engagement points with 6 pawls, housed in an aluminium body and using 100% ring bearings. A 22.2mm BOX Echelon seat/post combo is another high level component utilised on this build, along with a full hydraulic disc brake system that uses a Shimano lever and Forward calliper. Upfront, a chromoly Inspyre Evo fork has tapered legs that helps keep the weight down by reducing the amount of material on the fork.

Vee Rubber Speedster 20 x 1-1/8 tyres are wrapped around double-walled alloy rims, giving your sprocket, along with mum and dad, the confidence to send the big sets out there on the track. All in all, we're super impressed by the 2022 Inspyre Evo-C line of bikes and offer them in both white, and grey colourways for 2022. At this price point, these Evo-C bikes represent extremely good value as a complete race bike, especially when you look closely at the specification list. Racers at this level are usually looking at stepping up to a custom build as a way to improve performance, though this comes at a price that would be easily double of this bike here. Save yourself all that trouble of finding all the parts to build a bike and order a Evo-C. You won't be disappointed.

Features

Chromoly fork with tapered legs. The Inspyre Evo fork drops material where it is not needed, so there is less weight for a junior racer to muscle around.
Full hydraulic disc brake. A Shimano lever runs the Forward calliper on a 140mm rotor: stopping power a junior can use with one finger.
150 engagement points, six pawls. The Forward Joyride Disc rear hub picks up fast out of the gate, running 100% ring bearings in an aluminium body.
7.95 kg without pedals. A hydroformed 6061-T6 aluminium frame with an 18.75" top tube and 150mm cranks, sized and weighted for junior class.
Ready to race out of the box. Forward Joyride Aero double wall rims, Vee Speedbooster 20 x 1-1/8 tyres and a Box Echelon seat and post, all standard.

Assembly information

Your race 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
Spin the rear wheel and check the rotor runs clear of the calliper
Check the brake and tyre pressure before the first ride

Disc brakes: keep your fingers off the rotor and pads, because oil from your skin contaminates the braking surface and takes the bite away. If the rotor rubs, loosen the two calliper bolts, squeeze the lever, then tighten them again with the lever held on. Bed the brake in with a few firm stops before you race it.

Tools: Allen key set and a 15mm spanner for the pedals. Check your axle hardware, since race bikes vary between bolt-on nuts and a thru-axle.

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.

Race frames are sized by class, and the class you ride is set by rider height rather than age.

Size	Rider height	Top tube
Micro (18" wheels)	Under 120cm	16.25"
Mini (20" wheels)	110 to 140cm	17 to 18"
Junior	120 to 150cm	18.25 to 18.75"
Expert	130 to 170cm	19.5 to 19.75"
Expert XL	145 to 170cm	20 to 20.75"

Pro XXL	170 to 185cm and up	21.5 to 21.85"
Pro XXXL	175cm and up	22"
Pro XXXXL	180cm and up	22.5"
Cruiser (24" wheels)	175cm and up	21.5" and up

Heights overlap between classes on purpose. Where you land in two, a growing rider is usually better on the larger, and a rider who wants the bike to turn faster on the smaller. Some brands label the Pro size Pro L, with the same fit.

How to measure

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

Between two sizes and still growing? Take the larger size.
Racing gates and wanting the bike to turn faster? Take the smaller size.
Top tube is the number that actually changes the fit, so compare it against the bike they ride now.

Not sure? Send us their height and we will tell you what we would put them on.
