    A bit about us

    Welcome to our new website. We've spent a lot of time re-designing the site, listening to what you want and making the whole experience better. 

    You will notice that we use actual stock levels so you know when it's in stock and when it isn't. We have a fully integrated live stock system that handles stock from in store and online from one central database - plus we have live stock information from our key suppliers that allows you to see beyond what we have here within these four walls. This all helps to reduce the times you have to get an email to say what you ordered isn't available. 

    We know you're always looking for the latest stuff, so we work hard on bringing you hottest new stuff first. Available to order now with availability dates so you can place a Pre Order and get it before anyone else. 

    Our new Checkout process allows you to check out by creating an account, signing in to an existing account (your account from our previous site will still work), a "Guest" checkout so you don't need to create an account, lastly you can just Express Checkout with Paypal. 

    Finally our new shipping options allow you greater control on how your order is delivered with realistic delivery times - so you'll know when you'll get it. You get despatch and tracking information (when available) with all orders.

    Last of all if you have any questions, email sales@alansbmx.com or just call us on 01942 826598.

    If you have time please do some Reviews of the products you have used on here. 

    Thanks again for checking us out.

    Pre-Order

    With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

    You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!

    Pre-Launch

    With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

    So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

    G-Sport Birdcage Rim Black Description

  • Brand : G-Sport
  • Season :
  • Code : GSPRM003BK036
  • Weight : 0KG
  • From G-Sport:

    Someone told me a few years ago that there was nothing new left to do with BMX rims, yet since then we have gone on to do quite a lot of new stuff, and here’s an example of the latest. At first glance the Birdcage looks like a fairly conventional “aero” style rim, but there is more to it than that. The first clue comes from the name; birds have hollow bones to save weight whilst retaining as much strength as possible, and the Birdcage rim has a hollow bead for the same reason. The rim’s hollow bead is still big and chunky to help reduce the chances of pinch puncturing or flat spotting the rim, but by creating a tiny hollow cavity inside it we can also keep the weight right down.

    The next innovation was to adapt our cross-lacing design to the narrow inner wall of the rim. We managed to squeeze a few extra millimetres of spoke offset out of the design to help increase lateral wheel strength, and by carefully tailoring the rim’s cross-section we managed to match all the angles to the nipple so that the walls of the rim section act like the ribs inside the Ribcage rim, which helps to support the spoke nipples as much as possible.

    Traditionally, the greatest flaw in “aero” rims has been the valve hole. “Aero” rims position a lot of very efficiently utilized mass in the base of the rim to support the spokes and give the rim good strength, then a huge hole is drilled through it for the valve stem and a massive weak-spot is created. With the Birdcage we’ve offset the valve hole so that this section can retain its strength. A handy side-effect of this is that fitting a pump is now more convenient.

    Aside from these original features, we spent a lot of time “sweating the small stuff”. We’ve ensured that the deep center allows for easy tire removal and fitting, and we’ve made sure that the sidewalls, while slimmed down, are still suitable for brake use.

    The end result is one of our most high tech rims to date. With a weight of just 408g (14.4oz) it outperforms most rims weighing 20-30% more, and the weight saving from the rotational mass of the wheel feels fantastic.
