- h***h (559)- 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 6 monthsVerified purchaseThis Bottom Bracket works perfectly in my 73mm frame. Recomended.
- d***d (882)- Feedback left by buyer.Past 6 monthsVerified purchaseWorks well and arrived quickly.
- e***l (133)- Feedback left by buyer.Past 6 monthsVerified purchaseItem arrived as described. Due to the value, there was duty and fees to pay which made it 30% more expensive than the headline price, but this is par for the course, and not the seller's responsibility. Recommended seller, would use again.Paul Component Engineering Flat-Mount Klamper Disc Caliper, Road Short Pull, All (#125370468123)
- o***o (41)- Feedback left by buyer.Past 6 monthsVerified purchaseAccurate description. Good price. Well packaged with quick shipping. Clear communication from vendor. Very satisfied. Would definitely buy from this seller again.Shimano Ultegra ST-6800, 105 ST-5800, Tiagra ST-4700 STI Lever Hoods, Black, Pai (#125516221516)
- o***e (336)- Feedback left by buyer.Past 6 monthsVerified purchaseI pay for items instantly. I purchased this 6/24 and received it 7/2. I’ve had items shipped from farther on eBay that have arrived faster. Otherwise, the item was as described. Given the incredibly slow shipping & handling, imo the value offsets. I wouldn’t recommend but I also won’t go as far to leave a negative review.
