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, with an emphasis on speed and 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), whilst still maintaining class-leading stiffness where it is needed most, and not creating a bike that beats you to death after 10 minutes on UK roads. Our custom rolled ISP and topper system, whilst looking totally boss, and keeping weight and road buzz down to a minimum, also allows you to lie to yourself and pretend you’ve actually SAVED money by buying this frame, as you don’t need a seat post, it’s basically Martin Lewis approved.

As everyone at ISEN was too fat and slow to really show what this monster could do, so 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 the 2018 OVO Tour Series, which great success.

  • Frame is TIG welded, a mix of Columbus Spirit, Max and Life tubes as well as custom carbon ISP, specifically chosen for light weight, 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 offset (custom offset available on request).
  • Choice of BSA or T47 threaded Botton Bracket.
  • Proprietary STI cable stops so each frame can run mechanical 1x/2x, Di2/EPS, and wireless groupsets seamlessly and with no unnecessary bosses.
  • PMW replaceable mech hanger
  • 44mm headtube
  • Columbus Futura 1.5” tapered steerer Caliper carbon fork
  • Comes with Columbus headset as standard. Chris king headset available as £100 upgrade (RRP £184.99)
  • Direct mount rear brake for powerful braking,  under chainstay for clean looks.
  • Internally routed brake cabling

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.
