Dawes Kingpin. Mega-modded! https://raleightwenty.webs.com/apps/photos/ Dawes Kingpin. Mega-modded! Dawes Kingpin Fully modernised. Lots of fabrication and brazing. 2x10 Shimano Ultegra/105/Tiagra STI drivetrain components. Alienation Ankle Biter rims on FRM carbon hubs. Bontrager post, stem and bars. The frame, fork and rack are the only parts remaining from the original bike. https://raleightwenty.webs.com/apps/photos/photo?photoID=177553646 177553646 Chainset and front mech Shimano Ultegra chainset with 53/44 rings. Internal rear brake and gear cables. Braze-on front mech mount, with spacer block to account for angle due to small-wheel frame geometry. fabricated chainstay bridge tube with integral mudguard (fender) mounting boss. https://raleightwenty.webs.com/apps/photos/photo?photoID=177554440 177554440 Stem extender The stem extender has been fabricated from some 1 1/8" Reynolds 531 steel tube. Inside the fork is an Aheadset quill adaptor with an internal quill wedge. Inside the extender tube is a 25.4-27.2mm shim so that the extender tube fits to the quill adaptor perfectly. The lower clamp fixes the extender to the top of the fork. The upper clamp secures it to the top of the quill adapter. This 'belt and braces' method is the stiffest and strongest way to mount an Ahead stem to a Dawes Kingpin. The carbon spacers are cosmetic, and serve no structural purpose. The headset is a standard threaded Shimano 105 item, but the top nut has been reduced in height by 4mm. I also shortened the head tube by 6mm, thus allowing the lower clamp to align with the fork steerer's clamping slot. Safety first! https://raleightwenty.webs.com/apps/photos/photo?photoID=177554501 177554501 Rear mech Mega-exotic FRM Pro carbon cassette hub with Shimano Dura-Ace titanium freehub body. Ultegra 12-25 10-speed cassette gives the perfect range of ratios with 53/44 rings. 105 mech. Modified dropouts with brazed-on M6 rack mounts. Modified steel gear hanger. https://raleightwenty.webs.com/apps/photos/photo?photoID=177554719 177554719 Seat tube extender This is fabricated from a length of Reynolds 531 steel tube. The first version bent when ridden (tubing too light), so this one used a heavier gauge steel and has a boss brazed on the rear for a pair of tubular aluminium reinforcing struts. There's far too much flex without the struts. With the struts in place, it feels no more flexy that a conventional touring bike. Problem solved! https://raleightwenty.webs.com/apps/photos/photo?photoID=177554935 177554935 Clamping slot I've cut the slot at the front to avoid any pinching of the carbon post - which has been fitted using fibre-grip paste and a torque wrench. Whenever I make clamping slots, I braze a stainless steel diamond to the keyhole to prevent splitting. https://raleightwenty.webs.com/apps/photos/photo?photoID=177554936 177554936 Rear brake and rack mount I've brazed a new tubular brake bridge into the frame. This has a brazed in boss-tube to eliminate the possibility of crushing. The boss was made from a stainless recessed front brake bolt, drilled through 6mm. The rack mount was fabricated from steel tube. M6 rack mount bosses have been added to the stays. https://raleightwenty.webs.com/apps/photos/photo?photoID=177554937 177554937 Sexy hub! I had these super-exotic FRM carbon hubs spare, awaiting a suitable project. They are super-light and silky smooth. Best hubs ever made! Fork has been spread for a 100mm hub and offset has been reduced by 15mm. Crown has been edge-brazed. Mudguard (fender) eyelets and stainless face plates have been added. https://raleightwenty.webs.com/apps/photos/photo?photoID=177554938 177554938 Long stem A 140mm stem was necessary to achieve my position. I've used it inverted to keep the extender tube as short as possible. Top cap is Isaac carbon, mounted into an FRM expander plug. The cap and expander serve no structural purpose, but are a nicer way to finish the extender tube than a plastic plug. https://raleightwenty.webs.com/apps/photos/photo?photoID=177554939 177554939 Internal cabling I had to make several extra holes in the frame to achieve internal cable runs for both gear cables and the rear brake cable. Here you can see my brazed-on seat clamp in place of the horrible original steel band clamp. The aluminium struts do a great job of reducing seat-tube flex. https://raleightwenty.webs.com/apps/photos/photo?photoID=177554940 177554940 3/4 front I'm happy with the way it's turned out, but the rattle-can satin black paint is temporary. I did it that way in case any amendments were needed to the frame. The only amendment that disturbed the paint was having to add a ring-clearance dent to the RH chainstay. I was able to rub this smooth and blow in some fresh paint. I made the dent carefully with a ball-end hammer. Tiagra STI levers have been used due to their external cabling. I could have fitted 105, with gear cables under the tape, but worried that the extra friction, in conjunction with unorthodox routing, might affect performance. The gear change is perfect. https://raleightwenty.webs.com/apps/photos/photo?photoID=177554941 177554941 3/4 rear The end? Probably not. A removable carbon or aluminium top tube and a steering damper will perfect the handling. I'm working on it... https://raleightwenty.webs.com/apps/photos/photo?photoID=177554942 177554942 Test ride Big fat bloke on little tiny bike! Visiting a clubmate's house whilst out on the maiden test ride. 35 miles on a very cold day. Thanks to Bob for taking the well framed snap. https://raleightwenty.webs.com/apps/photos/photo?photoID=177556221 177556221
