Field X ENVE Track bike

March 22nd 2014

It’s not everyday you’re asked by ENVE Composites to build something special for their show stand at the Berliner Fahrradschau. With a shared passion for absolute quality and attention to detail, it’s exactly the kind of project we love to take on. The bike we created puts Field in the company of some of the most unique, beautiful and sort after bicycle makers in the world that ENVE have chosen to promote on their show stands in the past. We jumped at the chance to make something that shows off the unique frames we build.

With a similar build to Garreth’s Single fixed, but with an ENVE carbon seat post replacing the i.s.p this super stiff frame is built for performance, it excels racing through the city or around the steep banks of the track. Materials are a mix of Reynolds 853/631 and Columbus Life, with the use of a Tandem ‘boom-tube’ as the top tube to create a super stiff and precise handling frameset. The profile of this tube requires painstaking mitering and faultless fillet brazing to produce the sculpted and seamless transitions we craft. The oversized tubes provide us with a perfect canvas to indulge ourselves with another of the vibrant paint designs we’re known for.

Built up using ENVE’s incredible carbon rims and a unique Goldtec prototype stainless hub set, the super stiff ride qualities of the frame translate through the whole bike and leave nothing but a grin on your face.

XC 29er

January 16th 2014

This XC 29er was designed and built for a customer who wanted to make local trails interesting again. After a good few years of ploughing through obstacles on a full sus trail bike, there was a desire to return to the simplicity of a fully rigid bike and rediscover the skill of picking lines through the Peak. The first ride report was ‘fully rigid makes you pay attention!’

At the heart of the bike is a fast and zingy steel frame paired with a tapered full carbon fork. The simplicity of a fully rigid bike gives you direct and precise handling and the result is a compact, light and nimble XC bike.

The frame is fillet brazed with a Reynolds 853 front triangle, 44 mm i.d head tube. The Deddiccaiccai 9er Sero Uno chain stays with their new, more bendy shape, provide more clearance and work beautifully alongside custom bent Columbus Life seatstays. Stainless steel paragon machine works dropouts and a fillet brazed stem bring the frame together.

We went for a matte clear coat, making the frameset colours super saturated and vibrant on even the dullest of Yorkshire days.

Garreth’s Single fixed bike

January 1st 2014

Garreth’s bike is a really good example of the unique contemporary steel bikes we love to build. He encouraged us to exercise our collective skill and imagination across the design, fabrication and paintwork of his frameset. He left us to create something bespoke to his needs, trusting that what he got back would be his go to bike for the streets of Bristol.

We worked some unique features into this build; the most inventive is the top tube, starting life as a Reynolds oval Tandem boom tube, calling for some tricky mitering. The fillets were painstakingly filed and polished giving the frame seamless and sculpted tube junctions. At first glance looking more like a carbon frameset, but on closer inspection the lustre of the brushed stainless details confirm the frame’s steel heart.

We shot this bike on the road that bisects the huge Forgemasters site. A Sheffield company in its third century, regarded as the oldest steel business in the world. They still remain at the forefront of casting and forging steel for heavy engineering… producing the heaviest castings on Earth up to 350 tonnes!

We’re proud to play a lightweight part in Sheffield’s innovative steel working legacy.

Takashi's frameset
a modern steel race bike

August 21st 2013

This is the first of our bikes in Japan, built up as a fast race bike for Takashi’s local mountainous roads. It features a compact reynolds 853 front triangle, Columbus Life chainstays and our custom shaped S bend seatstays. Up front the oversized 44mm i.d headtube with our investment cast bronze headbadge makes a seamless front end when married to the ENVE composites 1.0 fork.

The paint is our most complex to date, Immaculately and painstakingly applied across the frame, fork and Cinelli integrated bars and it’s come out a treat. Inspired by snow capped peaks and alpine landscape, with a nod to the dazzle camouflage.

Cross/Classics Frame Set

June 17th 2013

Inspired by the functional ‘specials’ that get invented for the unique conditions of Paris Roubaix, this frame features a mix of cross and road geometry, with clearances for 35mm cross tyres. It comes into it’s own on the poorly maintained, rough potholed surfaces which punctuate our roads. The unique ride of steel combined with large volume tyres make for a fast, durable and comfortable bike.

Built with an integrated seatpost with a simple seatpost topper which gives +/- 30mm saddle height adjustment. the seat tube / top tube joint is sleeved for extra reinforcement over the rough terrain, and built to stand up to cyclocross use.

This bike also featured in issue 10 of Cyclist magazine.

The fillet brazed stem is painted to match the frameset, the machined steerer collar flairs on the bottom edge so the stem fits up nicely to the headset, a small example of the attention to detail that goes in to all of our bikes. On the front of the stem is the luxurious detail of a highly polished stainless steel ‘field’ braze-on.

Prototype 29er frameset

May 21st 2013

I am not sure if it’s my imagination or the brain region that deals with marketing kicking in, but it is the best riding and handling Mountain Bike I have thrown my leg over. It might just be the re invigoration that a new bike brings, or the fact that it has been built to fit me like a glove but I am really enjoying the fast and light steering on my local Peak District trails. It really helps when you’re picking your way up a rocky climb or through twisty single track - I am returning from my rides wearing a broader smile than usual!

GEOMETRY
 — Head angle 70
— Seat angle 73
— Fork length 450mm offset 54mm [trail 76mm]
— Chain stay length 440mm
— B.B height 300mm

More photos in the gallery

The frame is fillet-brazed construction, with a Reynolds 853 down tube and top tube. The integrated seat tube is plain gauge 0.8 wall 4130 Chromoly with a custom made seat post topper. The stem is fillet braze using 4130 Chromoly.

Rear triangle is made up of Columbus S bend chain stays and custom bent 4130 Chromoly seat stays.

The fork is built from 4130 Chromoly tubing; the custom made front and rear dropouts are C.N.C machined from 4130 Chromoly.

A little bit extravagant for a prototype but Cromaworks applied Tom’s design immaculately and we fitted one of our investment cast head badges on the headtube, the flecks of green on the bronze are verdigris patina. This is encouraged to develop in the traditional method with a certain bodily fluid!

Mario's cyclocross

January 29th 2013

Mario’s new disk equipped frame set. Reynolds 853 with a tapered 1/8″ – 1.5″ ENVE cross fork which looks huge when you get it out of the box, but it works well with one of our 44mm i.d head tubes, made from raw Reynolds 631 seamless Air hardening hot finished tube. we C.N.C machine them to the exact length we need.

The frame features immaculate paint work as always, by our in-house paint department CROMAWORKS with the ENVE cross fork painted up to match. We took care to include a few little finishing touches to complete this frame including a little scoop out of the seat stay bridge to trace the cyclocross tyre neatly, between custom shaped S – bend seat stays. An of course, one of our ‘Handmade in Sheffield’ bronze cast head badges took pride of place, mounted to the custom machined head tube.

Single fixed prototype

October 7th 2012

Designed as a single fixed road ‘trainer’ that was built by Harry to test out some new details: the 44mm I.D head tube is custom CNC machined by us from Reynolds 631 to have the right amount of material in it for a road frame. Heavily shaped S bend seat stays were fabricated in house using custom built tube former. The 35mm o.d oversized integrated seat post gives long ride comfort when combined with the S bend seat stays.

We went for Super high-viz for use in the approaching dull days and dark evenings of winter miles in the 

Peak District. Really fresh graphics by Tom and absolutely immaculate CROMAWORKS paint work by John.

The stem has an integrated top bearing cover machined out of stainless steel to work perfectly with HOPE headsets. It makes for really smooth transition to the custom machined over-sized 47mm o.d head tube.

Custom made 44mm I.D integral headtubes

August 19th 2012

Custom lengths C.N.C machined out of Reynolds 631 seamless Air hardening hot finished tube. These are a really tricky machining job: long and thin walled = vibration. But these are spot on. We were able to get them down to the sort of weight that is a sensible option for a road frame. Any size up to a 200 mm long, which should be plenty big enough for even the tallest rider.

These integral 1/18″ head tubes will work with tapered fork steerers with the use of an external 1.5″ bottom cup, like the Hope one pictured left. They also look ‘right’ with a modern carbon fork crown.

The best bit — they will look tip top with our very special integrated headset top cap stems!

I.S.P seat post fixed gear frame

August 7th 2012

A Field Cycles frame with an integrated seat post, not sure if its any better or worse from a frame design point of view, they do feel nice to ride, good stiffness and a better road feel than an Aluminium seat post. Its less practical if you need to pack your bike up, but it does look very cool and clean. A definite benefit is you will never get the seat post stuck in the frame with corrosion!

This frame is built with Columbus Zona Tubes and the great Llewellyn – XL compact Lugs. Another incredible paint job by CROMAWORKS again.

Edible track and bar stem combo

July 25th 2012

Thats all paint no stickers here, our CROMAWORKS paint just gets better and better - we’ve no idea how he does it so accurately. These we’re built using our custom jig, and available to order, with a range of angles and custom paint options, feel free to get in touch for more info.

Fixture-tron 8000

July 10th 2012

We’ve been busy recently building another custom jig, this time a fork fixture. We’ve spent a lot of time lately making the right tools to do the job. Its almost as rewarding as building a frame.

We’ve built it with plenty of room to get good access with the torch. It uses an Anvil bikes dummy axel to hold everything tightly in place and allows us to set the rake of the fork really accurately and quickly.

We sacrificed an old steel rule we had knocking about, its gone to a better place…

Fillet brazed stem with integrated top cap

June 27th 2012

Here’s one of our fillet brazed stems with a layer or two of paint. I am very in to the details, the stem bolts have been faced off on the lathe so they are a smooth and sharp as the rest of the stem. This features our super special integrated head set top cap. This stem is heading to our first international customer where it will be put to work on the roads of California.

We set aside the odd week to just build stems and our integrated track bars & stems. For more information regarding price, options, timescale and of course the endless possibilities of paint finish contact us.

The stripes and text below are all paint, no decals used so we can do any colours, completely custom.

Mario's track bike

June 12th 2012

Really happy with this one, a Field cycles team effort, built by Harry, super sharp graphics by Tom and immaculate paint work by John cromaworks. Mario’s track bike used a Columbus Zona tube set with Columbus Max fork and Cadenza over-sized lug set from Lewellyn Bikes to tie it all together. Built for single fixed road use with a brake hole in the Columbus Max fork crown to run a front brake.

It’s the first bike to feature one of our track bar and stem combos. The HOPE headset bearing cover is integrated into the stem steerer collar, all machined out of stainless steel for a super smooth transition and low stack. It’s also the first frame to have our freshly investment cast, bronze head badge adorn the head tube. We’re really looking forward to seeing the final build.

Clear-coat fillet brazed stem

March 18th 2012

We’ve been busy working on a few fillet brazed Stems, making use of our custom jigs. The ones shown here is 110 mm long at -16 degrees featuring 1 1/8th and 31.8mm clamps to fit nice stiff oversized road bars. We make these stems to order, in any length and angle required, with custom paint to suit your bike, get in touch to find out more.

Bronze headbadge

February 17th 2012

We’ve been busy kicking off the year developing and fine tuning an investment cast headbadge design. It’s taken a lot of time, effort and trial and error but we finally have a badge we feel is worthy of adorning our steel frames.

Bronze headbadge

December 17th 2011

Investment cast Bronze Headbadge, first one poured. It still needs some refining. You never know exactly what will happen until you make the pattern, invest it and then pour one. Its a very involved process, but once working produces fantastic results. Going to do a sterling Silver one for special occasions. The two holes top and bottom will fit M2 cap heads, to fit up to the head tube.

You can see the sprue on the back still needs cutting off and fettling.

New tool

December 2nd 2011

It doesn’t need explaining really, Its a sort of ‘braze on finger’. its really simple and effective, a joy to use! The ‘finger’ applies just enough pressure to hold the item in place for brazing.

Dave's cross… he's furious

October 28th 2011

Dave’s new cross frame, ready for winter. Fillet brazed Columbus Zona. Covered in another immaculate paint job by CROMAWORKS. A top quality job using all paint, no decals were harmed in the production of this paint finish! Looking forward to seeing it covered in Yorkshire’s finest mud.

Jigatron 3000 – Brake bridge jig

August 7th 2011

Another custom field jig, to hold a brake bridge in exactly the right place for brazing.

Integrated bars and stem

August 1st 2011

Custom fillet brazed track bars and stem, with integrated stainless steel headset top cap, for use with a Hope headset. Custom paint, length and angle options available. Just mail us.

We build these using our custom stem Jig which is all surface ground and bob-on. A stainless collar is brazed on to the stem to replace the top cap of the headset. The collar is then machined to match the HOPE headset top cap its replacing. All the groves for the HOPE O rings are in there. Gives a really nice transition from stem to head tube, minimal and super clean.

Ralph's 10 more than 30 birthday bike

July 23rd 2011

Just finished work on Ralph’s birthday bike after a good few hours in the Uber shed (a great place to finish frames, no distractions) with the needle files. In hindsight I should have photographed the process of me doing the 40, drawing, chain drilling, filing, filing, more filing, a bit more filing… here’s some of the details. 

Track bars and stem combos

January 22nd 2011

I am getting set up to produce the integrated track bars and stems. I have been busy making a few custom fixtures to set them up quickly and accurately for brazing. Allowing me to set the bars up for specific head tube angles, so I can accurately set the pitch of the bars. Really fast and convenient to set up. This has made a fiddly job simple – speeding up and simplifying the production a little. The Taiwanese bike factories are bricking it!
