  1. 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.
  2. It seems well made so far and shifts between the gears smoothly and quietly.
  3. 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.
  4. Unfortunately, I had to return this component, because of the weight.
  5. Undoubtedly, it would have provided trouble-free service, and normally would be a good replacement part for a worn derailleur.
  6. Also, apart from any psychological detriment, the added grams in weight would be undetectable.
  7. But my application is part of a comprehensive effort to lighten my bike, and this component was a poor choice on my part.
  8. 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.
  9. I began my repairs by searching and only needing a replacement for a broken hanger.
  10. My Tourney derailleur was a bit worn and worked horribly.
  11. The name ‘Shimano’ is supposed to be synonymous with quality, but my Tourney works like garbage.
  12. I was searching for the Shimano ‘Alivio’ but noticed the ‘Altus’ at half the price.
  13. 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.
  14. I decided that instead of going big I would give the ‘Altus’ a try, like betting on an underdog.
  15. I am so glad I did and totally satisfied with the results.
  16. One test ride and a final adjustment and it works beautifully through all 21 gears (7 in the rear).
  17. Smooth shifting and quiet, usually, unless stressed with torque.
  18. I finally feel confident in taking this mountain bike to the top of Santiago Peak.
  19. It cost a third of what I just spent on a repair part for my Sram XO derailleur.
  20. 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.
  21. I considered a new bike as I have many thousands of miles on this one.
  22. I decided to purchase this Altus buying the direct mount option in black to replace my tired Acera.
  23. Upon receiving the new unit it looked identical to the old unit except looking new and in black vs the old silver.
  24. Installation was easy for me as I work on my own bikes.
  25. 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.
  26. This is not a high end unit at all but excellent for the price range.
  27. This newer model appears to be better constructed and is lighter than the old one.
  28. Instead of a longer cage this derailleur has larger cogs that save some length.
  29. The cable connection works like a charm and after minor tension adjustment this derailleur operates smoothly and accurately.
  30. Thirty years ago the Deer Head RD was considered one of the best options for touring or mountain biking.
  31. But while I loved many things about this bike, the shifting was just never that smooth.
  32. However, after installing this derailer, shifting is much improved.
  33. If you want a poorly-shifting but period-correct derailer, then go get a deer head derailer from ebay.
  34. If you want a derailer than will improve the shifting on your vintage ride, then get one of these.
  35. This setup results in much more responsive, quick, and smooth shifting.
  36. The price was very affordable and the installation went smooth with no issues.
  37. The architecture of the point of attachment is complicated and there is no substituting one model for another.
  38. It will even hold up to some light MTB skills like bunny hops.
