Shimano RD-M310 Altus Mountain Bike Rear Derailleur
- The thing that I like most about it is that all the moving pieces are metal, because some parts of my old (OEM) derailer were plastic.
- It seems well made so far and shifts between the gears smoothly and quietly.
- It benefits from the company’s “trickle down” technology, where engineering gains on the top level Dura-Ace and XTR line eventually make their way down to the lower models.
- Unfortunately, I had to return this component, because of the weight.
- Undoubtedly, it would have provided trouble-free service, and normally would be a good replacement part for a worn derailleur.
- Also, apart from any psychological detriment, the added grams in weight would be undetectable.
- But my application is part of a comprehensive effort to lighten my bike, and this component was a poor choice on my part.
- The Shimano line of products remains worthy; as a side note, I ordered a Shimano Ultegra 6800 GS road derailleur in its place, which should elevate the shifting experience ALONG with shedding weight, on my vintage Klein mountain bike.
- I began my repairs by searching and only needing a replacement for a broken hanger.
- My Tourney derailleur was a bit worn and worked horribly.
- The name ‘Shimano’ is supposed to be synonymous with quality, but my Tourney works like garbage.
- I was searching for the Shimano ‘Alivio’ but noticed the ‘Altus’ at half the price.
- The Alivio I had seen on many bikes in bike stores as a standard for low to mid range mountain bikes and even street bikes.
- I decided that instead of going big I would give the ‘Altus’ a try, like betting on an underdog.
- I am so glad I did and totally satisfied with the results.
- One test ride and a final adjustment and it works beautifully through all 21 gears (7 in the rear).
- Smooth shifting and quiet, usually, unless stressed with torque.
- I finally feel confident in taking this mountain bike to the top of Santiago Peak.
- It cost a third of what I just spent on a repair part for my Sram XO derailleur.
- No carbon fiber, no bling factor, but the old derailleur my son’s bike came with had enough slop that it could not be adjusted to shift accurately.
- I considered a new bike as I have many thousands of miles on this one.
- I decided to purchase this Altus buying the direct mount option in black to replace my tired Acera.
- Upon receiving the new unit it looked identical to the old unit except looking new and in black vs the old silver.
- Installation was easy for me as I work on my own bikes.
- With new confidence that my bike has many more good miles in it, I will hold off buying a new bike and put a few more dollars into replacing the chain which is heavily worn and stretched.
- This is not a high end unit at all but excellent for the price range.
- This newer model appears to be better constructed and is lighter than the old one.
- Instead of a longer cage this derailleur has larger cogs that save some length.
- The cable connection works like a charm and after minor tension adjustment this derailleur operates smoothly and accurately.
- Thirty years ago the Deer Head RD was considered one of the best options for touring or mountain biking.
- But while I loved many things about this bike, the shifting was just never that smooth.
- However, after installing this derailer, shifting is much improved.
- If you want a poorly-shifting but period-correct derailer, then go get a deer head derailer from ebay.
- If you want a derailer than will improve the shifting on your vintage ride, then get one of these.
- This setup results in much more responsive, quick, and smooth shifting.
- The price was very affordable and the installation went smooth with no issues.
- The architecture of the point of attachment is complicated and there is no substituting one model for another.
- It will even hold up to some light MTB skills like bunny hops.

- It features a low profile concept with double servo-pantograph technology that improves adjustability and resists weather and contamination.
- The rear derailleur always keeps close to the cassette sprockets, allowing smooth and effortless gear changing.
