Lifeline Performance Cartridge Bottom Bracket Remover



Decent budget tool for occasional removing/fitting UN or ISIS pattern cartridge bottom brackets

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

The Lifeline Performance cartridge bottom bracket remover extracts and refits Shimano pattern splined bottom brackets that remain on common less expensive bikes, and there are plenty of older ones still around.

Good tools repays the investment countless times over. They won't maul expensive components or lead to lengthy explanations in casualty. However, unless you're afflicted by a chronic jet-washing compulsion and/or rack up over three hundred miles a week, you're not going to replace a fit-and-forget bottom bracket several times a year, even with a big fleet. Dependable rather than pro grade tools seem the savvy choice, therefore.

Eleven quid buys a simple but generally well executed socket on a stick, fashioned from heat treated steel. The business end locates into a rectangular head, locked in situ with a beefy circlip. Arguably welding the pair would create a stronger union, but this arrangement keeps costs down and is easily repaired should sloppiness eventually set in.

The Lifeline bottom bracket remover is compatible with Shimano UN and ISIS components. I was charmed by some less obvious but extremely thoughtful touches. A generous 15cm long, 3mm thick rubberised sleeve sits nicely in the palm, offering decent grip and moderate refinement.

Actually removing a bottom bracket proved easiest when liberal helpings of penetrant release spray were introduced and scrap frame tubing slid over the handle for additional leverage.

No such drama during installation, assuming of course you've remembered to baste threaded sections with some grease or plumber's PTFE tape. I found the Lifeline Performance tool fit best on Shimano's bottom brackets, closely followed by FSA and Stronglight units.

The Lifeline Performance cartridge bottom bracket remover should satisfy the needs of most home mechanics and those keen to recoup their money could even turn a profit by charging club mates a few quid for fitting or replacing theirs.

A competent budget tool that sweeps Shimano pattern cartridge units and in out with reasonable aplomb. However, fit is good as distinct from great and weathered bottom brackets still benefit from a quick blast of Plus Gas or similar penetrant

As a commuting cyclist I will not be rushing over to external BB any time soon. Square taper is pretty nails and fool proof and I am going to keep using it, BCD has not changed a lot so it's not a problem if I want to go for 10/11 speed, not that I would as i commute fixed.

This is one of the reasons I like roadcc. Not one of the most glamorous items to review, but given the same professional treatment as much more expensive items. Keep up the good work.
