1989 Bridgestone MB-1 (49cm / 19.3”)

***LOCAL Pickup in DMV area only ***
Original owner. Clearing out a spot in my garage as I bought a new bike and spouse insists an old bike must go. This was top-of-line for Bridgestone in 1989; the MB-Zip dropped in 1990.

Had in storage since 2003. This year replaced all drivetrain components (new chainrings, new cassette, and new chain (details below)), replaced tires and tubes (details below), replaced all cables and housing, repacked hubs (disassembled down to loose ball bearings, removed all old grease, repacked with new grease, and reassembled). Has both crankarm dust caps (one is original, the other a used OEM). 26.1 lbs (as pictured with pedals, toeclips, and straps; bottle cages; Blackburn pump).

Shimano XT groupset. 49cm (sizes available were 46, 49, 52, and 55cm); I am 5' 9". Full bike and part description at Sheldon Brown. https://www.sheldonbrown.com/bridgestone/1989/index.htm

This was my main mtb from 1989-1992, and once I got a hardtail I still rode this some until 1997. Then in storage for several years. Then rode it as a commuter bike for half a year in 2002. Then back in storage until this year. My guess is that I have about 5000 miles on it.

All parts original OEM except:
- stem: Tioga T-bone (had this 20mm longer stem swapped in when bought bike new in 1989)
- handlebars: Scott AT-2 (swapped bars likely 2002 when using as a commuter bike)
- rear wheel: Sun Rim CR17A on Deore XT hub (original rim got dented, likely replaced wheel in 1994)
- rear wheel skewer: Sugino (original Shimano skewer likely went with original dented rear rim/wheel)
- seat post clamp: Shimano (replaced 1995; OEM 'security' seat post clamp will come with bike)
- saddle: Terry Liberator Ti Race (make by Selle Italia, likely replaced 2002)
- chainrings: Origin8 in 46T, 36T, 26T (replaced 2023, same teeth count as original biopace rings)
- cassette: Shimano HG50 (replaced 2023, original 12-28 range, best quality 7-speed NOS still available)
- chain: KMC X8 (replaced 2023)
- tires: Michelin Country Rock 26x1.75 (replaced 2023)
- bar tape: Cinelli Gel Ribbon (replaced 2023)

The paint shows wear. But through the years, I regularly touchup painted chips (using Testors enamel model paint), so there is very little rust. There is one major blemish on the top tube, near the stem, where the rear brake cable rubbed through the paint. Check the photos - just forward of where the "Comp" sticker is on the top tube, driveside. Years ago, not interested in aesthetics, I sanded that out, touchup painted, but it’s far from perfect. And re-routed the brake cable to the other side, so that rubbing stopped.
