Basic Service

This service provides a basic check up that includes checking and inflating tyres, adjusting brakes, gears and headset. Tightening all relevant bolts to recommended torque settings. A safety check is also carried to identify any worn parts or areas of concern.

This is complete and full service that involves stripping your bike down to the frame. The frame and parts are then thoroughly cleaned and degreased before rebuilding the bike. During this process all mechanical brake and gear cables are replaced. Where applicable, the wheel hubs, headset and bottom bracket are also serviced. The wheels will be tensioned and trued. Any worn parts can be replaced during this service.

Dave Anderson's testimonial

Dave Anderson

Marius has an outstanding reputation with the core of road cyclists in the region. This is well earned. He has been building bikes for Azione since the early days. There have never been any issues. Our customers appreciate his care and quality of his work. So do we!

An experienced engineer, with years in the trade, makes Mariusz the finest bike builder for our customer's bike builds. Locally, many riders demand his services alone. His friendship comes for free.

Colin Blake's testimonial

Colin Blake

After 35 years of biking I may still not care about the intricacies of what gear ratios I am running, or where I can shave off an extra gram or two, or worry about whether that deep rim will make me go three tenths of a second faster - but I do care about how my bikes run. Lance Armstrong said it was not about the bike. Lance, you were so wrong on many fronts but especially that one. For me it is definitely ALL about the bike and like me, if you need your bike to run super sweet and super true Mariusz is your man. If honesty and reliability is important to you, then Mariusz will deliver every time. If it's expert advice based on years of experience in the cycle trade, then Mariusz is there to help you, absolutely no strings attached. Oh and by the way, he is a pretty good mechanic to boot! Give him a go, you won't regret it or I will eat my bottom bracket!.

Mark Elliot's bicycle

Marius has sorted not one but two bikes for me. The first was a new build: beautifully done, handled like a dream from the off and needed not one adjustment after. Superb. In a way though, the other rebuild on my winter bike was even better. For some reason unknown to me or others, and nothing we could put a finger on, the gears never quite worked perfectly.

Something minute, some subtle adjustment either I couldn't describe or the previous mechanics didn't quite get. But Marius sorted it: result, a bike as every bit as beautifully performing as the summer bike he'd done from scratch. Brilliant!

Mark Elliot

Bikeserve testimonial

When you get impeccable technical ability, knowledge and qualification, with exceptional trustworthiness, then add promptness too, you get the perfect mix.

I would happily recommend Marius's work to anyone.

Peter M Thompson

Bikeserve testimonial

I am a cycling coach and have been cycling for many years, during which time I have had a most diverse range of experiences with bikeshop mechanics…some OK, some downright terrible. I had never found a consistently good bike mechanic until by chance I happened to have some work done by Mariusz when I had decided to try a different cycle shop for my varied requirements. Given my previous experiences I entrusted my bike to this hitherto unknown mechanic with limited expectations but I’m delighted to say those expectations were greatly exceeded. Since my first experience of Mariusz’ work I have had a wide range of work performed from simple adjustments, services, to complete rebuilds, all of this work has been performed to the highest standards. The care and attention to detail Mariusz showed when working on my various bikes was and has been very impressive. I decided some while ago that whenever possible I will have any required work performed on my bikes by Mariusz as I have always found his work to be of the highest standard and importantly I have found him to be utterly reliable, honest and straightforward to deal with. I have no hesitation whatsoever in recommending Mariusz to anyone as a bike mechanic and I sincerely hope that he will be able to maintain my bikes for years to come, though I expect that he will become increasingly busy!

If you have ever been privileged enough to witness Mariusz at work, you might have had the same sense of awe that I experienced whilst watching him at work. He is so in tune with the machine, that his abilities seem almost superhuman. A few spins of the crank, a few revolutions of the wheel and he knows what needs to be done. Mariusz can occasionally be found helping at the Cycle Hub on Newcastle Quayside where the Cognoscenti go to have him mend, tend and repair their prized possessions. I truly wish Mariusz well in his new journey and am indebted to him for sharing knowledge and his time with me. No book can give you the skills that this man has and I often refer to him as a Wizard.
