1987/88 GT Timberline Ishiwata Chromoly
« on: March 02, 2013, 10:04:55 pm »

This is one of my collection of Old Skool Rides, it is 1987/88 GT Timberline. It was not a a very high end bike in it's day but I have always loved old GT's and when this came up I could not resist. I imported it from Italy and it is in pretty good condition for a 25 year old bike.

It is largely an exage trial gear set with a biopace crank and 18 gears, it sports a cool u brake and in even cooler adjustable seat post.











Although I am a sucker for originality but I also hate plastic brake parts so I have started upgrading the brakes and shifters. I sourced some Shimano XT thumb shifters and SLR brake levers in keeping with year of the bike. To keep the 80's feel I have also sourced some Vans grips for good measure. The bottom bracket was also shot so I upgraded this to a sealed unit that is 118mm wide to give better clearance for the u brake. When this is finished it will be my new commuter bike.







I will post a few pics when it is all finished.

After fitting the XT Shifters I decided to switch out the rear Freewheel for a 7 speed shimano one to replace the original 6. This would make use of the extra clicks from the shifters  :) at the same time I updated the original Exage Trail rear mech to a late 80's 500LX Exage unit which is a lot smoother and works well with new shifters.



Next jobs include servicing the hubs and new rear quick release axle.
