Pedro's Vise Whip



Answer to a mechanic's prayer but fixers will need to look elsewhere

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.

Thanks to Pedro's Vise whip, from now on my battered and unloved chain whip stays in the toolbox! Retailing at a cool £50 and backed by lifetime warrantee, it definitely falls into the (MARKETING SPEAK WARNING!) prosumer category-hardy enough for the rigors of a busy bike shop but within the reach of home mechanics. On the downside, track and urban fixer aficionados will cry foul since it doesn't entertain 1/8th sprockets and letting slip you've bought one will see the world and their club-mate camped outside begging to borrow it...

Designed with input from maintenance guru Leonard Zinn, the Vise whip is made from hardened forged steel, topped off in tasteful matt-black powder coat. Sharing striking similarities with the humble Mole grip, it works to the same principle- a set of precision machined jaws adjust via a knurled screw secreted in the left handle to fit sprockets between 11 and 23 teeth-as close to a universal fit as you'll find. Holding the cluster steady with the handles, freeing the lock-ring is simply a question of inserting the correct tool and turning this counter clockwise.

Having performed more cassette swaps in three weeks than the past three years I can confirm it's every bit as good as the hype suggests, largely eliminating grazed knuckles, frayed tempers and agricultural language when tackling the most weathered examples. Reassuringly hefty at 507g, it sits nicely in the palm without requiring Herculean strength to hold everything steady-my son, Joshua's eight and he managed just fine. The powder coated finish is remarkably hardy; will keep it looking fresh for a very long time while improving purchase into the bargain-even in greasy, sweaty palms there's been no hint of slippage.

Our test sample's adjuster screw benefited from a drop of oil but that's about as much maintenance as it's needed. Managing 3/32 sprockets, I took the lazy mechanics' route and set it to either 11 or 13teeth (road and tour/mtb respectively) with little cause to move it.

The Vise grip works to the same principle as a common or garden Mole grip and is simple, yet so well executed it's a wonder why it hadn't been thought of before. Spelling an end to juggling acts and grazed knuckles, tool quality is bang on and should withstand many, many years daily service. Frankly, with the notable exception of touring/roadside emergencies, I won't be giving the humble chain whip a second thought.
