- h***h (563)- Feedback left by buyer.Past 6 monthsVerified purchaseThank You SO Much, Gap30 Cycles !!! ... SO Glad to get this Brand NEW, Genuine, HIGH Quality, Original Shimano, 73 x 123mm, BB-UN300 Bottom Bracket Sealed Wheel Bearing set. The Price was GREAT, considering The BIGGEST Store wanted $35.00 +/- - My final price was HALF of that !!! - It's a Beautiful unit, ... BUT ... Way TOO MUCH Blue threadlock applied, at factory. I had to remove most of it with lacquer thinner - I am intending on keeping My Bottom Bracket "serviceable", in the future.
- 0***p (12)- Feedback left by buyer.Past yearVerified purchaseThis Bottom Bracket works perfectly in my 73mm frame. Recomended.
- k***l (543)- Feedback left by buyer.Past monthVerified purchaseExactly what I was looking for and reasonable price.
- n***d (279)- Feedback left by buyer.Past 6 monthsVerified purchaseThe cassette arrived quickly, but was missing 1 cog (I believe the description said "new, open box" so I'm sure they didn't realize there was a problem) The seller gave me a full refund and asked me to dispose of the cassette on my end. I believe I've ordered from them before, very happy with the transaction, despite the issue with the missing part
- a***s (1442)- Feedback left by buyer.Past monthVerified purchaseGood packaging, fast shipping and item as described however, bike pedals were tight and unusable without adjustment. Seller offered free return but kid had to ride his bike so.. seller did not offer partial refund so we suggested to check future sales and quality control to avoid this problem in the future. Thanks for the good communication Gap30, D&J
- c***_ (145)- Feedback left by buyer.Past monthVerified purchaseOrdered at a bad time without thinking about it (A friday). Come monday i was making a trip into asheville anyway and just decided to buy this part from a shop. Seller's response times to messages and requests are fantastic, and the cancelation and refund process was totally painless even though it was 100% entirely my fault. Should they have something i need, will def be doing business again with this seller.
