    recently purchased a Shogun bike frame from this seller, and I want to take the time to share how outstanding the entire experience was. Buying bike frames online can sometimes feel like a gamble — you never quite know if the item will match the description, how it will be packed, or whether communication will be smooth. In this case, I can honestly say that everything about this transaction exceeded my expectations. First and foremost, the seller was extremely professional in their communicati

    The item arrived exactly as ordered, with all parts, in brand-new condition. The postage was expensive, but well worth it, as the packaging was extremely sturdy, and the item arrived sooner than expected. I was able to mount the rack on my Townie in minutes, with just an Allen wrench. The purchase price was well below REI's MSRP for this item. The only thing the seller could have done better is include a photo of the mounted product; that would have saved me a few minutes figuring it out!

  • fairly good dura-ace front derailleur

    not a bad derailleur. usable. but will not last very long. the left inside of the cage is almost worn down to the brass. after that the unit is scrap. person who had this must have let the cage rub on the chain rings constantly or it has been really used for a long long time. price was a bit high for such an old unit,,,but not worth the hassle to return. mark clement bend, oregon

  • Used good condition

    Needed it for my latest build. Several thousand miles so far. Even down here on the flat ground that amounts to “several” smooth shifts.

  • Very nice piece of kit!

    Bought this for a circa 2004 Iron Horse road bike I bought off a friend of mine who built it up from spares he had. It had Dura Ace on the rear derailleur but Sora on the front and I just thought it deserved an upgrade. This fit the bill and works great!
