Culprit Junior Kids & 650C Aero Road Bikes Makes Small Fast
Hot on the heels of Culprit’s aero disc/canti road bike comes his two kids and 650C aero road bikes specially designed for children and really, really short people.
The Culprit Junior One, above, is the kids’ bike and is spec’d and sized specifically for fast little tykes. The story of the bikes begins, as most things do, with an unmet need. We’ve seen several kids road bikes from custom builders, but trying to find a well spec’d performance road bike for children isn’t easy. One of Josh Colp’s (Culprit’s founder) friends was looking for a race-worthy bike for his son and couldn’t find it, despite also working in the industry.
The Junior One and 650 Junior Two are made of double butted 7005-series alloy with welds smoothed after manufacturing for an almost carbon-like appearance.
On top of a quality frame, a solid standard parts mix was used where size concerns weren’t an issue: Shimano 105 derailleur’s and cassette, a KMC X-10 chain and TRP 820 brakes.
The handmade Culprit aero carbon seatpost has a two position saddle mount to give the bike a longer life as your kid grows.
Frame size is one thing. Component spec presented a whole ‘nother set of challenges, and Culprit ended up making some of the components in-house. To accommodate the smaller hands and reach, a shallow drop 360mm wide, 26mm reach handlebar was used.
They custom made 140mm crankarms with a 105 BCD and 40/32 CNC’d chainrings.
Lastly, the Junior One gets handbuilt 20″ wheels with 30mm deep front and 40mm deep rear aero rims. Pricing, geometry and specs for both bikes at bottom of post. This oughtta give that $8,000+ Kirklee kid’s tri bike a run for its money!
CULPRIT JUNIOR TWO 650 AERO ROAD BIKE
The Junior Two gets the kid’s name but larger 650C road wheels, a bit more common among smaller triathletes. Spec is similar, and because they use many standard components, there’s a lot of room for upgrading the bike should you and your ilk really get into the sport.
The Junior Two gets 152mm crankarms with a 110 BCD 46/34 CNC chainrings on the Junior Two (below). The front derailleur mount has room to accommodate a standard compact gearing of 50/36.
Those weights in ‘merican are 17.4lbs and 17.74lbs respectively, making these lighter than most kids bikes out there. Pricing is $1,550 for the Junior One and $1,625 for the Junior Two. Both bikes come in gloss black with your choice of red, blue or yellow logos, and they come with a color-matched junior sized jersey.
Colp will be at both Eurobike and Interbike with this, his UCI-approved road racing bike and the disc/canti Croz Blade.
