The pads and rim and are subject to functional wear. Sporty use or riding
in wet terrain shortens the life of the pads. Check the pads regularly and
replace them as needed. You can acquire replacements from Hummingbird
or from your local bike shop.
Rim brakes not only wear out the pad, but also the rim itself. Therefore,
check the rim regularly such as when inflating the tyre. The sidewall of the
rim contains a tiny groove that functions as a wear indicator. When this
groove is no longer visible, the rim must be replaced. If deformations or
cracks in the rim sidewalls occur when inflating the tyre, the rim has
reached the end of its service life and needs to be replaced.
The bearings on Hummingbird are designed to ensure a long lasting life,
service-free. However, environmental conditions such as rain, dirt etc.
cause these moving parts to wear out. These areas must be cleaned
regularly. Depending on the operating conditions it is possible that these
parts may need to be replaced due to wear, which will become evident
through development of bearing play.
We designed Hummingbird with as many standard parts as possible and
as such, you can service your bicycle by approaching any authorised
bicycle repair shop. You can contact us for any assistance and service
advice. Upon request we can refer you to your nearest qualified bike shop.
TAKING CARE OF YOUR CHAIN
The best way to prolong the life of a chain is to clean and lube it regularly.
Clean the chain in situ using a chain cleaner, then lube each roller
individually, keeping the lube away from the outside of the chain. Try to
avoid the temptation to run the chain backwards and apply lube in a hurry
— it’s wasteful and can overload the links. When you’ve finished, wipe off
any excess lube with a cloth.
When cleaning the chain, avoid driving any degreaser or cleaning products
into your bottom bracket or freehub body as this can strip the grease from
these parts, causing all sorts of problems. Lastly, always wipe down and
relube the chain after wet rides to avoid it rusting and seizing up.
