Lugform FAQs
What does the £595 cover?
£595 is the introductory price for the frame kit. You choose and buy the bike components separately.
How is Lugform different from the other gravel kits?
The Gravel Frame Build Kit joins the tubes with flax and epoxy wraps. The Gravel Lugged Frame Build Kit uses pre-formed aluminium lugs. Lugform uses 3D-printed aluminium lugs with shaped sockets and provisions for internal routing. The Complete Gravel Bike Kit includes bike parts alongside the standard gravel frame kit.
How do I choose a size?
Compare the stack and reach with a bike that fits you. If you’re between sizes, ask us before ordering.
Why are the aluminium lugs printed?
Printing lets us shape the lugs to guide each bamboo tube into place and build cable entry points into the joints.
How will the cables and hoses run?
Lugform is designed to route cables and brake hoses inside the frame. Tell us which drivetrain and brakes you plan to use and we’ll help you check the routing.
Will my current components fit?
See the component guide. Send us the model names and tyre size so we can help you check parts you already own.
Will it take mudguards and racks?
Tell us which rack, mudguards and tyres you intend to use so we can help you check mounting and clearance for your size.
Can this be my first frame build?
If this is your first frame, the build guide will tell you what tools and space you’ll need and how long to allow. You can also ask us about the build before you order.
When can I order?
Pre-orders are open for the first batch. Choose an available size to reserve your kit at the £595 introductory price.
When will my kit ship?
See Dispatch and delivery for the current estimate. Delivery time and cost depend on where you live.
