I have completed the rebuild of the Ascent. It was a clean bike to start with so it really didnt take much. I did update the tires to some MTB Knobbies and replaced the black riser bars with the wrong clamp diameter. with some chrome flat bars.
A good clean up and new cables is all it took.
DB Cro-Mo Sticker on the Fork and Tange MTB Frame Sticker.
Original Sugino GT Cranks in great shape and the Diamond back Sticker on the bottom of the seat tube
Original Suzue “sealed hubs” on the flip side is the original Shimano 5 Speed Freewheel. Even the original Chrome Spoke Protector was in great shape. I usually take them off but it was in such good shape i decided to leave it on.
The Flat bars and Shimano AT50 Brake levers with Friction shifting. (yes pre SIS)
The Shimano AT50 Cantilever brakes were in great shape so they just got a clean up and brake pads were scuffed up.
1989 Centurion Ironman before images:
60 CM frame, Frame gfx are in pretty good shape. alot of scratches on the frame itself. The rear wheel is incorrect for the bike. the brake cable is to short, not even enough to go through all of the braze ons. Brake levers are not the original Suntour GPX but DiaCompe Gran Compes. i did dig the red cables and red hood and bar tape
Original Suntour GPX Cranks with GPX front deraileur
Suntour GPX Rear Derailuer and replacement Shimano 7 speed Freewheel
Suntour GPX Brake calipers. they are kind of neat as they have hidden brake springs.. Look ma no springs.
Crazy late 80’s decals nothing could be without geometric shapes. higher quality frame with Tange #1 tubing
Logo says it all Expert IronMan Dave Scott.

I have been enjoying this bike. i have returned the pedals back to the stock 105 Toe Clip pedals and dare i say ..yes i added back the Biopace Chainrings. the bike is original enough i felt the bike needed the original chainrings.

Back in 1987 for my birthday i recieved a brand new Diamond Back Ascent, This was my first Mtn Bike. It was really cool to have a real Bike. It was a Red bike with 1st gen Light Action SIS Shifting. fast forward to 2015. I found this a 1986 Diamond Back Ascent. in Chrome! These are hard to find. The Chrome in good condition is even harder to find.
Pictured here with a era correct Vetta Rack and Continental Town and Country tires.
I plan on Doing a full rebuild and clean up with the original components. and adding some mtb tread tires.
More Pics to come….
finally someone has posted scans for the 1986 & 1987 Centurion bicycle catalogs!
they are here:
My latest acquistion, is a 1987 Centurion Dave Scott IronMan Expert. This bike is in great shape the frame has very little scratches. it is the Magenta and Yellow paint scheme which is mistaken for Pink quite regularly. This one is a 60cm Frame. it is mostly original except for a few pieces.
I have wanted one of these for many years, in fact since they came out, i remember seeing them at the Bike Shop and hoping one day i would own one. Now i do!
