Vintage 1989 Miyata 914 54cm frame fork CrMo steel black Shimano bottom bracket Japan
Frame and Wheel is auctioning a vintage 1989 Miyata 914 frame set on the Frame and Wheel eBay Store. The frame set was purchased new at Dave’s Bicycle Infirmary in Milton, Massachusetts as a completely built-up stock Miyata 914 bicycle in the early 90s. The bicycle was used recreationally and occasionally until about three years ago, when the owner backed his car into it, bending the rear rim beyond repair. The bicycle has been in storage since then. The owner is the original owner and he is selling the frame set because he needs to clear out the basement of cycling equipment and he does not want to invest any capital in restoring the bicycle. The frame set features Chromoly (Cr-Mo) steel tubes and front fork, spline triple butted tubing, adjustable rear drop outs, internal cabling on the top tube, investment cast lugs, double water bottle cage mounts, down tube boss for a Co2 cartridge cage, down tube shifter bosses, bottom bracket shell cable guides, pump peg on the head tube, seat stay chain hook, Japanese provenance and distinctly late 80s graphics. The frame set as shown weighs 3.2 kg (7 pounds). The serial number on the bottom bracket shell reads QS36935. The serial number on the front fork reads DJ 244 T M 1063. A 1988 Shimano 1051 bottom bracket is included. Seat post not included. All of the frame set’s original components and the front wheel are being auctioned simultaneously on the Frame and Wheel eBay Store. There are over 100 images of the frame set at Frame and Wheel Auction Services Please take a look.
Review of condition
The frame set is in good condition. Although it shows wear, it is clean and ready for build. There are no dents, bends or cracks in the frame or the fork. There is no bubbling in the finish. The rear drop outs are in alignment with the the centerline of the frame and the rear derailleur hanger is straight and undamaged. The steer tube is not bent or showing a bulge. The front drop outs are in alignment with the centerline of the frame. All the pieces of the headset are included. The head set bearings are not corroded and run smoothly. The headset races are not pitted or corroded. The steer tube threads are not stripped. The cups are clean and not cracked or corroded. The bottom bracket threads are not stripped and there is no corrosion. The bottom bracket cups are not pitted or corroded. All the parts to the bottom bracket are included. There is no corrosion in the water bottle cage bolt holes and the bolts are included.
Frame and Wheel notes the following. There is a 5 x 5 mm patch of corrosion around the first cable stop on the top tube. There is a 2 x 3 mm patch of corrosion on the top of the top tube lug. There is a 2 x 10 mm abrasion on the side of the non-drive side top tube near the second cable stop. There is a 5 x 5 mm patch of corrosion on the non-drive side down tube in between the “i” and the “y” in Miyata. There are smaller patches of corrosion near the “y” in Miyata.. The sticker for the second “a” in Miyata is peeling. There is a 25 mm scratch on the non drive-side chain stay near the intersection with the bottom bracket. The clear coating on the non drive-side chain stay is flaking. There is a 70 x 20 mm area of scratches on the drive-side chain stay from the chain. There is a mark on the seat tube from the front derailleur clamp. There is wear around the drop outs. The right rear drop out adjustment screw is bent.
Frame and Wheel conclusion
Frame and Wheel’s view is that this a fine vintage frame set that will make a nice fixed gear bicycle for the urban hipster or an inspiring restoration project for the steel road bike aficionado. It shows signs of wear, but it is in good condition and ready for build. The accenting of fluorescent shapes and lines brings to mind Duran-Duran and MTV, but the statement is subtle and clearly does not affect what is excellent Japanese craftsmanship. The new owner will enjoy restoring this frame set and will relish its classic steel road feel when the work is done. A great opportunity to obtain a very good quality classic steel frame set at an excellent valuation.
