Just what I needed
Jenson has fantastic service. Ordered one day, it came the next. Felt like a pro mechanic this was so easy to install and adjust. Put it on my old Marin Rocky Ridge. A perfect replacement. Crisp clean easy shifting. Chain must be broken to install. It's why I use a chain with easy link separation. Somehow it gave me greater ability to cross the chain up (greater numbers of gears to use) without rubbing, while still giving that fast shifting.

PROS: Highly Compatible

BEST USES: Cross Country, Casual Trails

More Deore
I've ridden enough bikes over many years with front mechs made by numerous manufacturers to know what I like. For me, SRAM and Shimano are the standouts in dependable, long-lasting value.

While recently updating a few of my daily rides, I felt compelled to spend a few dollars more to upgrade rather than simply replace parts. One disappointing trip to the LBS later and I was online searching Jensen's catalog for a new front dérailleur and what better match for my Deore cranksets than Deore dérailleurs?

Out of the box the build quality is other level when compared to the old SIS, Tourney and Acera lines I grew up abusing. The polished cage to reduce chain wear (and shed mud), easy cable routing and beefed up clamp with full shim set told me I had picked a winner.

Bottom line: the only part of shifting now detectable is the next gear. Smooth, quiet and reliable.

PROS: Easy to adjust, Refined, Lightweight, Smooth, Rugged, Highly Compatible, Attractive

This is a response...
This is a response to Mathews 1 star review:ALL front derailleurs get "sloppy" after awhile, it is part of the regular tuning that is involved with using a bike.

Great Derailleur
This Shimano Derailleur was super easy to install and works really well! I can't believe I didn't replace my old busted derailleur sooner! It shifts very quickly and easily. Great product!

Smooth Shifts in Tight places
Good shifting with the flexability of cable routing from TOP OR BOTTOM. With the low clamp it fits in FS frame.

PROS: Fits Most Frames, Reliable, Smooth shifting, Alows Top Or Bottom Cable

Smooth Shifting Mech
While my experience thus far involves decidedly lower-end derailers, the XT-M770 Deore paired to a modern crankset makes for quiet, smooth and trouble-free shifting.

Let's face it, the derailer pushes the chain around period! If you're in need of a good quality front then I can recommend the Deore. Replaced my old Shimano with worn cage on a 3x7 Trek and alls well.

PROS: Adaptor Shims Included, Highly Compatible, Attractive, Rugged, Easy installation

Perfect
Needed a new derailleur for my ride and this turned out to be a perfect replacement! Very happy with the purchase and price. Perfermance is spot on and appreciate the versatility of cable pull in case I use it on a different ride! Thanks Jensen for the great service!

Great derailleur
Great product used to replace base deore that gave me good service. This derailleur shifts perfectly. Installation of clamp-on derailleurs is always a challange since you are working in 3 dimensions. Alligning vertically is easy but getting the allignment parallel to the chainring is a challange, persist and the rewards are SMOOOTH shifting.

PROS: Rugged, Highly Compatible

CONS: Persist During Install

Love it
After dealing with a SRAM 7 front deraileur and being told to pedal easier to get it to shift correctly, I upgraded. This is exactly what I was wanting. no lag, goes where I want it, no problems.

PROS: Accurate, Reliable, Strong

CONS: Need Cable

Amazing upgrade
Upgraded from an old LX. Can't say the weight loss has made a huge difference, but it does shift very smooth and has for the last 3 seasons I've had it. The shims are nice in case I ever switch frames as are the routing options. For the price you can't beat it!
