Bike Builder

WHY BUILD CUSTOM?

Mass-made Off-the-Peg bikes are great but they have their limitations; theyʼre designed to be average, to serve more people and satisfy the varied needs of a large potential customer base.
With a ʻcatch-allʼ approach and a fixed budget can come concessions in functionality.
What might be marketed as a bike for “everyone” can instead be a bike that is perfect for some riders but just isnʼt quite right for you.

With a custom-build comes the freedom to choose anything you want based on your own needs as an individual rider.
This freedom can be confusing and intimidating...

How do you know which rims are stiffest? Which parts can be easily serviced at home? Which groupset is compatible with your frame? Do you really need to have a Chris King headset?

Our custom bike build options do away with all the nonsense, removing the need to study bike brand websites and become an expert before you make your purchase!


Weʼve put together options that use some of the best components out there.
None of the recommendations we make are “cheap” but some are better on your wallet compared to higher-end parts but all are GOOD; they work well, have lasted through the abuse weʼve submitted them to and weʼre happy to recommend them.

Once youʼve made your picks and paid your bill, weʼll be in touch to confirm all of your selections. You can expect to have your custom one-of-a-kind Seabass build fully assembled and ready to ride away inside two weeks. Weʼd much prefer to have you collect so we can size you up, fit the bike to your body and set up the contact points for you but shipping can be arranged if you canʼt make it to our shop.

If you find our bike builder to be too limiting and it doesn't cover the specifics youʼd prefer, simply drop us a line and weʼll build your one-of-a-kind for you just the way you want it.

We’ve selected a handful of premium framesets from some of our favourite brands around the world. These are all versatile frames loaded with functionality for every type of riding you can imagine. Each frameset features disc brake functionality, wide tyre clearances and a steel frame at its core for a comfortable ride and a long-lasting bike. All our builds will come installed with a sealed bearing headset from Cane Creek as standard. The clamp, seatpost and stem will be unbranded entry-level hardware.

The groupset is the mechanical ‘heart’ of the bike. Each element serves its role in order to control the gear shifting, braking and powering of the bike. All of our options are hydraulic or “hydro” disc groupsets. These represent the pinnacle in braking performance. Far superior and longer lasting than a traditional rim-brake and not compromised by all-weather riding. A 1x11 or “One By” system means one big ring up front giving a total of eleven gears. Less mechanically fussy and features a wide spread of gearing options, perfect for most city and gravel applications. A 2x11 simply means two big rings up front. Twice as many gears. Perfect for longer touring or bikes with lots of luggage.

Your wheels are responsible for holding your weight and are your direct connection to the road, trail, tow-path or wherever your bike takes you. The best wheels are hand-built and finely tuned. Seabass custom-builds ONLY come with hand-built wheels.

Tyres affect grip, handling, speed and ride comfort. We ride Teravail and we think they’re perfect for our custom-builds. All our wheel-builds are ‘tubeless compatible’ - you can run them WITH or WITHOUT an inner tube. (If you select a 650b tyre, we will build you 650b wheels rather than 700c)

There are many types of bars and they all have their own benefits. Drop bars will give varied hand-positions for shifting your weight around and altering your position when spending a long time on your bike. Flat profiles will offer limited hand positions and a more relaxed riding position. Drop bars will come wrapped as standard with SUPER STICKY KUSH bar tape and aluminium expanding bar-end plugs. Flat bar options will be fitted with VANS x CULT waffle grips.
