Trek 7.4 fx Nexus 7 speed hub gear bike specialized bicycle sirrus hybrid commuter
Trek multitrack hybrid bike with shimano nexus 7 speed in gear hub gears (low maintenance and great for winter), rear hub brakes with v brakes with newish pads, front 700x35c bontrager puncture protection tyre, and rear Schwalbe marathon plus 700x35c tyre puncture protection (£45 on its own!), large 20" size. Excellent condition with a few chips and marks as to be expected. New chain and cables recently. Not used much since. Comes with rear top peak pannier rack and rear mud guard. Here’s Ged’s 12 reasons you might want to consider Nexus hub gears on your next bike: The Nexus 7-speed transmission offers an excellent range of gears (equivalent to an cassette) – wide enough for most riders on most roads in Britain. You change gear with a simple twist of the Shimano Revo gear shifter, pictured. You can change one gear at a time or shift from top to bottom (or vice versa) in one twist. Unlike a derailleur, you can shift gear when the bike is stationary – this is really useful if you have to stop at the lights halfway up a hill – no more setting off in too high a gear. Enclosing the gear mechanism inside the rear hub makes for a more weather-resistant transmission. The lack of derailleurs removes one of the more vulnerable parts of a bike (the rear mech and/or its hanger often take the hit if the bike is knocked over). The fact that the chain does not spend its life being derailled from cog to cog improves its life expectancy too. From personal experience, I’ve found that a Shimano Nexus transmission outlasts an equivalent multi-cog derailleur system by a factor of at least two. The Nexus hub is a fine piece of Japanese engineering, developed by Shimano over the past 20 years. The Nexus hub alone retails at £150. With its single chainring and single rear cog a Shimano Nexus setup offers much of the simplicity and the minimalist aesthetic of a single-speed bike. Ad ID: Delivery Service Consumer Credit
