What is a "custom bike build"?

A custom bike build is a bicycle built to your specifications, not pre-configured by a manufacturer. The level of customisation varies:

• Level 1: Custom component build (BikeClinique's specialty) — you buy a frame (off-the-shelf), and we spec the groupset, wheels, finishing kit to your riding, fit, and budget. Labour from £600. Frame typically £500-£3,000. Total £2,000-£7,000.
• Level 2: Made-to-order frame + custom build (Quirk Cycles, Landrace, Big Fun Bikes) — frame is made to your geometry, paint, and spec. Components chosen separately. Total £3,000-£10,000+.
• Level 3: Fully bespoke frame + build (Quirk, Landrace, select few) — full geometry, custom tube selection, paint, complete bike. Total £6,000-£15,000+.

The custom bike build process at BikeClinique

Step 1: Consultation (30 min, free)

30-min phone or in-person consultation. We discuss: what you ride now, what you want, your budget, timeline, riding style, fit considerations. No obligation.

Step 2: Frame selection (1-2 weeks)

You choose the frame — from a manufacturer, a custom frame builder, or we help you decide. We can source frames from any major brand (Specialized, Trek, Canyon, Giant, Ribble, etc.) or work with a custom frame builder (Quirk, Landrace, etc.).

Step 3: Groupset, wheels, finishing kit selection (1-2 weeks)

We spec the groupset (Shimano/SRAM/Campagnolo at any tier), wheels (off-the-shelf or custom-built by us at £75+ spares), and finishing kit (handlebar, stem, seatpost, saddle, bars, tape). All chosen to your budget, riding style, and aesthetic.

Step 4: Parts sourcing (1-2 weeks)

We source everything. UK-based suppliers where possible, with warranties. You get one invoice, one delivery, one point of contact.

Step 5: Assembly (1 day)

Frame prep (cable routing, grommets, battery mount if Di2), full assembly with torque specs, all adjustments, cable tension, brake bleed if hydraulic, Di2 firmware update, test ride, fit check, handover.

Step 6: 100-mile check (2 weeks after delivery)

Free 100-mile check. After 100 miles, cables stretch, bearings settle, things shift slightly. We tighten, re-adjust, re-bleed if needed, confirm everything is still perfect.

Where do I get a custom bike build in London?

BikeClinique for custom component builds (most common, best value). Quirk Cycles, Landrace, Hackney Peddler, Big Fun Bikes, Bespoke Cycling, Goku Cycles for custom frame + build. Each has different specialties (steel vs Ti vs carbon, budget vs premium, race vs touring).

Is a custom bike build worth it?

If you have specific fit, performance, or aesthetic needs that off-the-shelf bikes don't meet, yes. If you want a bike that fits you perfectly, has exactly the components you want, and reflects your style, custom is worth the premium. If you're happy with off-the-shelf sizing and don't have strong component preferences, save money with a stock build.

Can I bring my own frame to BikeClinique for a custom build?

Yes. We build bikes from any frame — frames you already own, frames you're sourcing, frames from custom builders. We just need the frame, the build specs (groupset, wheels, finishing kit), and the labour payment.
