Why Buy From Us?
Why Buy From Us?
Why Buy From Us?
We're one of the most well established bike shops in Scotland and have been selling bikes to Glasgow and far beyond since 1980, so you can be sure that we're not going anywhere 😀
We care about what bike you buy, and we want it to be right bike FOR YOU, not one that would suit us. If you buy your bike from us, we want to keep you as a customer and keep your bike riding perfectly. We offer a free 6 week / 300 mile “tune-up” service, where we tighten up bolts and cables, index your gears and generally sort out any small issues you have after the short bedding in period.
You'll also have priority access to our workshop for repairs or servicing. We never turn away someone who has bought their bike from us, no matter how busy we are. You may have to leave your bike with us for a couple of days, but you'll be at the top of the list.
We offer free loans of a hard-case Bike Box Alan if you're travelling with your bike, just tell us when you need it and we'll book you in.
The best (and cheapest) time to make changes to a bike is at the initial build stage, avoiding the need to re-cable, bleed brakes etc. We can swap your saddle, change stems, wheels, tyres, bars, cranks, bar tape, group-set, pedals, add luggage and mudguards - the list is endless.
If you're ordering online, just select your upgrade or pop a note in the order when checking out.
Very few bikes leave the shop as they came to us, with stem and tyre changes being the most common.
Bikes are fully built up from scratch by our Cytech Level 2 mechanics. Brakes are bedded in on our brake bedding roller. Being situated in Glasgow, we’re used to preparing bikes for our wonderful British weather so everything is greased up to suit a Glasgow winter. Bikes are then buddy checked, test ridden and re-boxed for shipping with minimal assembly at your end.
High-end website sales are likely to be shipped in a hard case requiring minimum rebuild - attach the wheels, fit pedals (remember pedals are specific to the side of the bike) and away you go. We’ll arrange return shipping for the bike box.
Have you had a bike fit? Send us your fit data and we’ll set up the bike to your position.
Small adjustments make such a big difference.
Are the gears low/high enough for you? Do you have the correct tyre width? Favoured tyre brand? Fancy going tubeless? We’ll make suggestions that will improve your cycling enjoyment.
Bike-Fit is a big part of the in-store service, and usually involve swapping saddles, bars and stems. Whether it’s our suggestion or your requirements, we’re here to help you buy your perfect bike.
