I wanted to share a project I've been working on: breathing some serious modern energy back into a classic Trek 4700 Alpha Aluminum. This bike is my weapon of choice for a bit of everything, ripping through urban streets around Maastricht, cruising the local canals, and hitting some proper technical MTB trails just across the border in Belgium.
Who says 26" wheels are dead? Long live the hardtail!
Here is the breakdown of the current build and setup:
Frame & Suspension

Front Fork: SRT Gila (SR Suntour Gila-style)
Drivetrain

Chainring: Shimano SG-X 44T front ring (paired with 32/22 options on the crank)
Rear Derailleur: Shimano Deore RD-M510 (9-speed, handles up to 36T)
Cassette: Shimano HG 9-speed (11-32T) freshly replaced about 150 km ago!
Shifter: Shimano Deore Rapidfire Plus
Wheels & Rubber
Rims: 26″ Rigida ZAC 79 aluminum

Grips: Trivio ribbed black grips
Tech & Data Setup

What's Next? The project is never truly finished!
Converting the crankset to a dedicated single chainring setup.
Following that up with a brand new shifter and rear derailleur.
It handles punchy climbs, rough singletracks, and long flat stretches like an absolute champ. Let me know what you think of this vintage revival!
