Custom Geometry and Options on 18Bikes steel hardtails


Anvil Journeyman Jig offers massive adjustment

Here’s where we think we offer something realy quite unique! Our frame jig offers huge scope for sizes and angles - we’re really not limited there! From our side of things, there’s 2 points to consider for geometry on a hardtail MTB.

-sizing and how it fits the rider

-geometry and how it suits your riding style

We don’t work from a standard outline geometry, instead talking with a customer about existing bikes and how they fit and any requirements regarding components. We then use Bikecad software to plan the frame - this is a real two-way process, with feedback both ways.

While other “custom” framebuilders only offer some choice in angles and lengths, we have full options for;

- suited to fork length/travel

-headtube length

-effective top tube

-reach and stack

-bottom bracket height or drop

-seatube length

-headangle

-seat angle

in addition to the components used to fabricate the frame

- 1 1/8” or taper headtube

-standard/eccentric bottom bracket

-dropout style/designs

-brake mounting

-cable/hose guides and routing

-bottle and mudguard bosses

We can also cater for any unusual specifics for a certain component, such as Rohloff cable routing, extra guides for light leads or even height adjustable seatposts.

In short - if you’ve an idea/design in your head - just ask, it’s highly likely we can say yes!
