Next up we have one of the excellent Frog bikes. A real competitor to the likes of Islabike…nice light frames with excellent componentry. This one was purchased on-line and arrived with skipping gears. Rear derailleur adjusted and cable tension amended and all gears were accessible with lightning changes.
Busy week after being off for a couple of weeks convalescing. First up there’s a Saracen Tufftrax that came off second best to a chunk of rock…well, it’s rear derailleur did anyway. The gear hanger needed adjusting to bring everything back in line, and a new Shimano MTB Tourney rear derailleur fitted. Gears adjusted and it was off again.
This Condor had been in a couple of weeks ago with a very, VERY worn bottom bracket. Its owner needed it in a hurry for a charity ride he was doing the same weekend. Unfortunately, the bottom bracket cups wouldn’t shift as they were corroded tightly in place (not a lick of anti-seize had been applied I assumed). Fast forward a couple of weeks and its owner asked me to try again as it was virtually un-rideable. So, using a slightly Heath-Robinson solution consisting of bolts and thingymajigs, I finally managed to shift it. As you can see the bottom bracket shell was in a state.

Once cleaned up, and the threads chased, it was time to fit a new Shimano bottom bracket, re-fit the crankset and double-check the chain line. Result? One very happy owner and a (slightly) relieved bike mechanic.

Specialized Sirrus in for some ‘sirru-ious’ work. When collected, the rear derailleur was in pieces and wrapped around the rear spokes. Derailleur extricated, gear hanger gently corrected back to its original orientation, replacement gear cable and derailleur fitted and rear wheel trued and it was back to commuting duties for this one. Oh, and a new chain…always best to try and keep on top of these things if you possibly can.
