The simplest fix is the last place you look

My boss has just asked me to have a look at his commuter bike as it was 'really draggy' this morning. Disaster, as he commutes a fair distance on a very busy A road and had a long and difficult journey home ahead of him. 'It wasn't doing this yesterday' he says, 'maybe the frame's bent?'. 'I'll take a look and see' I say. Spin the wheels and the back is rubbing terribly. Boss looks highly concerned, assuring me it was fine only last night, it must be knackered. Look a little closer at the disc caliper and it's rubbing like crazy. So, undo the bolts and realign it - pretty much to no avail. After some fiddling around it turns out he hasn't put the back wheel in properly and it's simply not bolted up straight. Simple fix! Sort of, rear brake was still 'pulsing'; realign the caliper, still no joy. Discover the disc is slightly bent so I suggest it needs replacing. Further investigation however shows it's another extremely simple mistake. The spacing spring on one side of the QR was put on back to front so the fat end overlapped the axle and was lifting the wheel ever-so-slightly on one side. Put that on properly and Bob's of no relaiton to you, all problems solved. A small spring the wrong way around and a wheel not in properly. I couldn't help but chuckle at how two such small errors had rendered the bike for scrap

I take the springs out the rear QR's as they serve no usefull function, even the right way round I've seen them get mangled and create issues.
Front I keep them in to centralise QR across the Lawyers lips.
Good story though.Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0 -
Have done that before :oops:bluechair84 wrote:The spacing spring on one side of the QR was put on back to front0 -
It's funny that I've never done this, but also I've never known why they had to be this way around. It's been a sixth sense to have them narrow side in all these years... I now know!0

I spent half an hour messing with a brake last night before checking if the thru axle was mounted correctly. It wasn't.0

Strangely, that is exactly the same reason why I read it...bluechair84 wrote:Just a simple story shared as I've loads of work to do and no motivation to do it.

always glad to help someone procrastinate. Which somehow sounds very different when read aloud...
In other problems; I discovered the knuckles in his front mech are so worn that it's rattling around, and his cassette lockring isn't done up tight enough so the cassette is wobbling too. I think I'll just take in my whole tool box and spend a day on it instead of doing actual work.0 -
My retro has a very rattly front mech, still works fine though!
Cassettte lockring or fubarred freehub bearings?Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.0 -

Some of the sprockets wobble independently of one another, so I'm pretty sure the lockring will sort them. But, I hadn't considered that. Will be the next check if the lockring tool don't fix it 0
