Race Ready Road

Frameset from £2250. A deposit of £1125 is required with balance on completion. 

We spent years developing our first bike, the All Season. We wanted something that could be used all year round, whether on gravel paths, club runs, touring, audaxing, commuting, almost anything you could throw at it. It’s a great bike, and has served us and many ISEN customers admirably but we realised that by pretending we now only need one bike in our lives, we were just lying to ourselves.

So we set out to make the polar opposite of the All Season, a one-track minded road weapon. Developed with leading UK crit riders and emphasising speed, effortless handling and ‘chuckability’, the R3 was born. There are no allowances for all year riding or any attempts to make the R3 a do-it-all frameset. Mudguard mounts? For cowards. Rack mounts? No way grandad! We’ve mounted the rear brake at the BB to maintain the clean lines of the frame, sub-optimal if you’re commuting every day in slush and slime, but perfect for turning your bestie into a green-eyed monster. We’ve chosen the lightest tube set possible – a mix of Columbus Spirit and Life – to maintain class-leading stiffness where it is needed most whilst minimizing road buzz thanks to our custom rolled carbon ISP and topper system.

As everyone at ISEN was too fat and slow to really show what this monster could do, we gave the prototypes to local elite riders who have a far lower volume and higher velocity than ourselves. So far they have repeatedly won races at the renowned Crystal Palace Crits, and ridden in the 2018 OVO Tour Series, with great success.

Performance Road Bike.

  • Caliper and Disc brake specific options available.

  • Suitable for mechanical or electronic caliper groupsets.

  • Frame is handmade in our London workshop. TIG welded, from a mix

    of Columbus Spirit, Max and Life tubes as well as custom carbon ISP, specifically chosen for lightweight, BB emanating stiffness and saddle emanating compliance.

  • Comes with carbon ISP as standard. All our carbon tubes are custom specced and handmade for us. This allows us to keep weight down, easily integrate Di2/EPS battery systems, and fine tune ride characteristics.

  • Handmade seat topper, available in 0mm or 20mm off- set (custom offset available on request).

  • Full carbon Columbus Futura Caliper fork with 1.5” tapered carbon steerer.

  • Choice of bottom bracket: BSA or T47 threaded.

  • 44mm headtube.

  • Squircle shaped downtube and bi-axially ovalised top tube.

  • Direct mount rear brake for powerful braking, under chainstay for clean looks.

  • Internally routed brake cabling.

  • Hand cut asymmetric lugs for carbon ISP.

  • ISEN asymmetric seatstay bridge.

  • Hand formed ISEN solid brass headbadge.

  • Caliper brake specific - QR front and rear (100mm front, 130mm rear).

  • Disc brake specific - 12mm bolt through front and QR rear (100mm front,

    135mm rear).

  • 700c wheels, clearance for 700x28c (sizes 51-61cm).

  • 650c wheels, clearance for 650cx28c (sizes 47-49cm)

  • PMW replaceable mech hanger

  • Choice of five ISEN Workshop sikcandyfadez® paint schemes.

  • Frameset or full build options.

BB Choices.


We offer any of our bikes with either T47 or BSA 68mm BB shells.

BSA is the traditional BB system used on bikes for decades, and works very well. There are many options for BB’s and cranks at all price points and parts are easily sourced. If you were riding around the world you would want a BSA BB shell for ease of sourcing parts.

T47 is the frame building communities answer to BB30/PF30 BB systems. BB30 was originally designed by Cannondale, and has bearings that press (not thread as per BSA) into the frame. They are oversized and are designed to work with cranks utilising a 30mm axle, larger than the 24mm axle on Shimano cranks for example. This is advantageous as stiffness in the BB area is ‘free’ stiffness, it doesn't create any adverse ride quality issues that increases stiffness in other areas of the frame can. It also makes internal routing of Di2, dynamo wires etc far easier. However, due to the thin wall thicknesses on bicycle tubing, both BB30 and PF30 have been beset with issues with creaking, bearing surface damage and repeated development of play. T47 is the best of both worlds. A threaded bearing cup to remove any creaking issues, with the oversized bearings to allow the use of high end 30mm axle cranks. Any cranks designed for PF30 or BB30 will work, and BB’s are supplied by Chris King and white industries, who have both said they will not discontinue them as a product, so you won’t be stuck with an obsolete BB standard in 10 years. If you want the ability to run the best cranks, want your BB to be as stiff as possible,or plan to run wiring internally, this is the standard for you.
