Pre-Order

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

Your 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; ready for collection via Click & Collect or despatch 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.

Estimated Delivery & Collection Dates

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Returns & Exchanges

Straightforward rules for change-of-mind returns, exchanges, and faulty gear — plus your rights under Australian Consumer Law.

30DAY WINDOW
Most items can be returned or exchanged within 30 days of purchase, unused and in original condition. Full detail below.
01

Change of mind

We'll happily exchange or refund most items within 30 days of purchase, provided they're unused, unwashed, and in original condition with tags and packaging intact.

  • Proof of purchase required (receipt, order confirmation, or card statement)
  • Original packaging and any included accessories must be included
  • Refunds are issued to the original payment method
Not eligible for change-of-mind return: ridden or fitted bicycles, cut or installed cabling and hoses, opened nutrition and hygiene products, and custom or special-order parts.
02

Bicycles

New bikes may be exchanged or refunded within 14 days if unridden, with pedals, tags, and protective packaging still in place. Once a bike has left the store assembled and ridden, it's covered by warranty rather than change-of-mind return — this is a safety and hygiene standard across the industry, not just ours.

A restocking fee of up to 15% may apply to full assembly and setup already carried out on a returned bike.

03

Faulty or incorrect items

Under Australian Consumer Law, you're entitled to a repair, replacement, or refund if an item has a major fault, doesn't match its description, or isn't fit for its intended purpose — regardless of the 30-day window above. Minor faults may be repaired within a reasonable time.

This applies to bicycles, components, and accessories alike. Bring the item in with proof of purchase and we'll assess it on the spot or send it to the relevant brand for warranty review.

Online orders & shipping costs

Online orders can be returned to Giant Canning Vale in person, or posted back to us. For change-of-mind returns, you're responsible for the cost of shipping the item back to us, and original delivery charges on the order are non-refundable — this is standard practice and consistent with the Australian Consumer Law, which doesn't require a retailer to cover return freight or refund delivery fees when a customer simply changes their mind.

We recommend using a tracked service for change-of-mind returns, as we aren't responsible for items lost or damaged in transit before they reach us.

Faulty items are different: if gear is genuinely faulty, we cover reasonable shipping both ways — getting it back to us, and sending your replacement or repaired item back out — in line with our ACL obligations. Pay postage upfront to return it, and we'll reimburse that cost once the fault is confirmed.

Bikes are sold and fitted in-store only and aren't shipped, so this section covers gear and accessories.

06

How to return something

  1. Bring the item to Giant Canning Vale with your proof of purchase.
  2. Our team checks it against the conditions above — this usually takes a few minutes.
  3. We process your refund, exchange, or repair booking on the spot.

Posting an online order back to us instead? Include your order number and allow 3–5 business days for processing once it arrives.

Shimano RD-R9250 Dura Ace 12-speed Di2 E-tube Rear Derailleur

Season:Non-Seasonal

Brand:Shimano

Code:IRDR9250F

Digital integrated intelligence or di2: with programmed automatic motion at the touch of a switch the Dura Ace Di2 rear derailleur is quick, smooth and effortless, making for unmatched drivetrain efficiency.

Features:
  • The rear derailleur is now the brains of the system with wireless connectivity to the shifters. It acts as the point the system is charged, provides Ant+ connection to 3rd party devises and replaces the handlebar junction
  • Button on the derailleur for Di2 operations, and led light denotes synchronized shift mode, setting mode and charge requirements
  • Programmed automatic motion at the touch of a switch makes this derailleur quick, smooth and effortless to shift
  • Synchronized shift designed, developed to choose the next biggest or lowest gear ratio irrespective of whether a gear change needs to be made by the front or rear derailleur
  • The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching
  • Low profile shadow derailleur design
  • Derailleur contains a saver (fuse) function, where the inner structure is protected from strong impacts
  • 11-34t wide gear ratio capacity will cater for compact setups as well as the traditional road double
  • Full carbon fibre inner and outer pulley plates enhance rigidity and reduce weight
  • Titanium b axle bolt for further weight savings
  • High tolerance cold forged aluminium link plates and body construction is extremely light and durable
  • Four self-lubricating micro-machined fluorine-coated link pivot bushings provide low-friction shifting
  • Pulleys are made of tough dupont zytel for longer life and less chain noise
  • 12-speed e-tube Di2 compatible
