General information about our shipping
Replaced my old square tapered BB with this 105 Hollow tech BB, very surprised with the ease of fitting to the bike and it makes a great difference to pedal stroke, much smother action, I was thinking of going for the Tiagra BB but instead paid a few quid more for this, highly recommend if your BB needs changing and cheap enough at the price, as always Merlin delivered very promptly.
Reliable and durable bottom bracket. Got one for the parts box at this price!
Simple to fit and its is replacing one which has given many years of faultless service.
Cant go wrong with a Shimano 105 BB. Reliable, smooth and very well priced.
Great item, fits perfect, looks nice and goes the job. Been in a week and done over 100 miles. Only time will tell how long it will last.
Better than pressfit!
Always go for 105 kit, very well priced, durable and dependable.
Item arived new in the box. It's a great bb and the ride quality seems exactly the same as the Dura Ace one I have on my Ultegra crank (I'm pretty sure Dura Ace only offers a weight advantage). After it is installed the crank does not spin free. When you try to spin the crank it will stop before a full revolution. I'm pretty sure this is just how Shimano is making their bbs now as my Dura Ace does the same (it loosened up slightly after a few rides but not much). Once you're on the bike and pedaling that friction is not noticable and the crank spins very smoothly. I fit this on a bike I'm rebuilding with a FSA Gossamer crank. The spindle fit was tight and needed some pursuation, but then again the bb was designed for a Shimano crank. After the spindle was knocked in it rode as well as my Shimano on Shimano set up on my other bike.
Good b/b does what I want it to do, easy to put on (buy a proper tool) will see me through some bad weather this winter, goes well with the 5700 chainset I bought also, service first class from Merlin (as usual)
Great piece of kit, bought in conjunction with Shimano 105 5700 Chainset, previous set lasted 20 years. Next day delivery, great service from Merlin.
Very good!
Hard to get too excited about a new bottom bracket but this is easy to fit and no problems. Great price, packaging and delivery as always from merlin.
I upgrade from 9-speed to 10-speed, changing the triple crank to double one. That causes me to change everything. I must have spent more money, but here "Merlin" gave me good prices. Thanks so much, Merlin!! Next time again I will definitely come and buy some, I swear. I was lucky I found this nice internet shopping. Thanks.
Great product easy to fit. Speedy delivery!!
Does exactly what it says on the tin. Easy to fit and gives you a chance to clean out all the crud from your frame at the same time.
Can't go wrong for the price. I seem to go through bottom brackets quite regularly on my cyclocross bike so a cost effective option like this is ideal
