The Top Fuel 9.9 SL – Di2 and internal-routed dropper post compatible
Here’s Trek’s new Top Fuel. The bike is designed to cope with the very rough nature of today’s almost bike-park-like, cross-country race courses. It’s a 100mm race bike with 29in wheels for all sizes apart from the 15.5in size, which gets 27.5in wheels.
The 9.8 SL. Girl’s paint, now for boys!
The frame weight is 1,900g for a medium. The chainstays have shrunk from 452mm to 435mm, partly due to the Boost rear end. There’s also a Mino-Link which allows riders to tune the geometry by 0.5mm and the BB height by 8mm.
The Top Fuel 8 WSD keeps the same geometry as the rest of the bikes in the series, but gains a women’s saddle and custom paint.The regular version of the Top Fuel 8.Top Fuel SL C – all of the goodness of the Top Fuel, in a frame-only carbon guise.No news yet as to whether or not the 9 comes with sunglasses. Pow!
With 25 years as Editor of Singletrack World Magazine, Chipps holds the record for the longest-running mountain bike magazine editor in the world. He started in the bike trade in 1990 and became a full time mountain bike journalist at the start of 1994.
Chipps stepped down as Editor in April 2026 after 25 years at the helm. He's now wondering what to do next, while riding his bike in the French Pyrenees, where he also runs some gites.

‘tune the geometry by 0.5mm’

0.5 degrees HA/SA adjustment I guess?
Hey, the theater wasn’t that hot. Outside, on the other hand…
