The right tool for the job

I don’t want to create Tool Envy but… Our new USA manufactured bearing extractors and small bearing press have arrived.
(No we don’t use a hammer and sockets to remove or install bearings…!)

Only grease-monkeys need get excited, the rest of you can carry on as normal.

Suspension Pivot Service – Giant Trance 2009

This 2009 Trance belongs to a 100kg (plus) rider who likes to work it hard over the downhill single-track and he isn’t afraid of big drop-offs.   The bike came into the shop this week – 8 of the 10 pivot bearings were ‘notchy’ and 2 were almost seized.  All the bearings needed replacement.

Suspension bearings do not rotate – they move within a specific fixed range and this can cause more rapid wear than normal rotational forces.

We suggest that you inspect your bearings if:

  • the rear suspension creaks
  • if you have put in some heavy riding but have never had these bearings serviced
  • if the back end of the bike starts feeling harsh or ropey
  • if you plan on riding a major race

A seized bearing can crack or damage the frame and is potentially dangerous.

Fortunately this bike was checked in time and should give many more years of fun on the trail.
