Dahon Puncture!

Saturday October 22, 2011

Took the Dahon out today as I was spending the morning out and didn’t want (or need) to take the car.  The trusty bike was a great ride as always and the 3.5 mile round trip was very nice on a cold autumn morning.

Back home and the Dahon was placed in the hallway and left whilst I had a coffee.  Shortly after, the rear tyre was completely flat and the bike leaning to one side.  Hmm, a damn puncture.  Will need to take a look at that, but not today…

Gerber Sport Multi Tool – UK streel legal?

Sunday July 3, 2011

I’ve had my Gerber Sport multi tool for a long time (bought from Heinnie.com).  These days it’s with me when I’m out taking photographs and I have carried it on me when out cycling too.  However, reading the letter of the law, it’s illegal to carry this multi tool in public due to it’s locking blade.

Today I removed the blade from the tool so that I could confidently carry it whilst out and about without fear that I was carrying an illegal blade.  I don’t use the blade that often so it’s removal isn’t too annoying.  The pliers and screwdrivers are the useful bits on the tool and now they can come with me everywhere.

To remove the blade, you just loosen and remove the bolt/pivot at the base of the blade.  Then you can pull the pivot out and the blade and two screwdrivers fall out – take note of the orientation of the bits at the pivot before attempting this!  I then replaced the blade (on the pivot) with two 1mm washers and put the bolt back on.  Perfect.  The tool still functions as in its original configuration but I no longer have the illegal locking blade.  An easy and quick modification which can easily be reversed if needed.

Trek 4300 – March 2011 Upgrades

Saturday February 26, 2011

Upgrades or downgrades?  I’m planning on changing the quick-release skewers on my Trek 43oo to standard non-QR skewers.  This should make securing the bike much easier when out and about.  Now I realise that a determined thief could still nab the wheels but I don’t plan on leaving the bike for long periods anyway.  Even if I do, I can still loop the lock chain through the wheels.  Changing to non-QR skewers would make short term locking much easier (for example: nipping into the shop for five minutes).

I’m also looking to replace the quick-release seat post collar with a non-QR variety so I don’t have to lock that each time too.

I’m thinking of ordering the parts this weekend and then giving the bikes their spring service during the next couple of weeks (time permitting).

Pedro Tools

Thursday August 26, 2010

I stumbled across this tool whilst browsing the ‘Net earlier this week, it’s the Pedro Trixie.

Specifically designed for the fixed gear rider, the Pedro’s Trixie is the urban survival tool with all the right pieces to keep that fixie rolling.  Hardened tool steel give this tool a great feel and long lasting life.

  • 15mm box end wrench.
  • Lock ring hook.
  • 8,9,10mm box end wrenches.
  • 5mm hex.
  • Of course, a bottle opener.

And whilst looking at that, I found their Tülio seat post tool which replaces the QR fixing on your seat post – I thought that this was a great idea.

Tülio provides the functionality of a standard quick release mechanism while providing a multi-tool at the ready which includes eight of the most commonly used bicycle tools – 4,5,& 6mm hex wrenches, an emergency 8mm hex wrench, a No. 2 flat head screwdriver, a chain tool (single-speed -11 speed compatible) and a pair of spoke wrenches (3.23mm & 3.45mm).

    Schwalbe Marathon Plus Tyres – Trek 4300

    Saturday March 6, 2010

    Tyre ComparisonWith a lot of miles forecast for 2010 I’ve set about modifying the Trek to make it better suited for on-road use.

    This doesn’t mean that I’m never going to take it off-road again, or that I’m regretting buying a mountain bike over a road bike, but I just need to be able to adapt the bike to the sort of cycling that I’m planning on doing.

    Having clocked up a few long rides on the stock bike, I thought that the best mod, and the first to tackle, would be to change the tyres.  Off came the standard knobbly ‘tractor’ tyres and on went a set of road-specific Schwalbe Marathon Plus.  I’d contacted they guys at Dotbike for some advice on an alternative tyre and they came back with some suggestions which included the Marathon Plus.  So, I placed my order (along with some other bits) and whilst there also bought some Schwalbe inner tubes to fit at the same time.

    Fitting the tyres was as straight-forward as any tyre fitting and they look pretty good on the bike, making it look more ‘road-worthy’ than with the stock tyres.  They’re 26×1.75 tyres which makes them a bit thinner than the tyres I removed, which were 26×2.25.

    The only thing I don’t particularly like with the Marathon Plus tyres is the 3M reflective strip on the sidewall.  I know that this is a pretty good safety feature, providing extra visibility at night, but I’d prefer the option to not have this feature – purely for aesthetic reasons.  But still, it’s probably best to have this feature on long rides when you’re not sure at what time you’ll be returning…

    I haven’t managed to get any miles on the new tyresTyre Width yet, maybe tomorrow, but a quick ride along the street showed them to be very smooth and comfortable.  The flatter tread and lower rolling resistance should improve comfort and speed on my long rides.

    Photos over on Flickr along with photos of the mods I’ve made (saddle, rear rack, grips).

    Dahon Bottom Bracket – Loose

    Monday June 8, 2009

    I think I’ve mentioned before, either here or over on the Dahon Forum, that my D7HG makes a ‘clunking sound’ when I pedal.  This has been happening more or less since I bought the bike but I finally worked out what it was last weekend when out cycling.

    I had initially thought that it was related to the internal workings of the Nexus hub and the drive mechanism ‘catching-up’ with itself as I pedalled.  I left it at that and just lived with it.  But then, as I cycled recently, I thought more about it and looked at the bike as I slowly cycled along the flat.  Then I realised that it was the bottom bracket – the piece where the pedals attach to/through the frame – it was not loose (see photo below).  Not sure if this was an original assembly issue, pre-sale check issue or it had just come loose.

    Anyway, I needed to tighten it up and didn’t have the right tool for the job so I headed to my new favourite bike site Dotbike for a BB lock ring tool.  Now the lock ring and bottom bracket are correctly secured and that should stop the clunking noise as I pedal.  I now need to get out and try  it, but that won’t be today.

    I also grabbed myself an Ice Tools Spoke Wrench.

    (Hmm, why do my bikes always look dirtier in photos than they do in the flesh?!)
