Considering the speed of a cyclist, and the amount of time a car takes to cross a cycle lane when turning left, there seem to be only three possibilities:-
a) The car driver didn't indicate until the last moment. It is pretty normal that most of those motorist who do indicate do so by sticking out a finger as they start to turn the steering wheel.
b) The car driver overtook and turned left whilst indicating
c) The driver was in a queue of slow moving or near stationary traffic, and turned left without checking their mirrors.
In all of these the car driver is at fault.

Re: No room on the ferry for my bike...
I'd recommend the telephone.
Websites and cycle bookings often don't work properly. It may be necessary to book without the bike, then call and add the bike to the booking. By report, the LD Lines system won't cope with more than one bike per booking either, so if there are two of you you have to make two separate bookings (a bit of a pain when there are 15!

Re: 132.5mm droputs good idea?
I'd look on 132.5 dropouts as a minus point when considering a frame.
You can use either road or MTB hubs, but use is more awkward with either than it would be with the right size frame.
If using road hubs, the 2.5mm is more than the throw on a typical QR lever (XT=1.5mm) so you would have to undo and readjust the QR every time you took the wheel out.
If using MTB hubs, using one hand on each seatstay to spring the frame leaves no hands for putting the wheel in place.

http://www.travelpass.buytickets.scotra ... 294&To=307 and there are still tickets for July.
You need to book the bike as well by phone to Scotrail. I am booked the other way Euston - Inverness 24 MAy - no hassle with packing boxes etc. For me there is just no comparison - quicker cheaper more comfortable(?)than a bus
There is a very detailed thread downline - search "bargain berths"
Hope this is of help

Note the limited bike bookings on the sleeper from Inverness - 3 per train
Standard non-bargain fare is £64, iirc

Re: Rim and tyre widths
As far as the tyre is concerned, what counts is the internal width of the rim. The external width is typically about 6mm larger than the internal width. The rim should say what internal width it is with a "13-622" or whatever sticker, but I wouldn't rely on it. The manufacturer's websites often state the external width only.
Tyre width should be in the range 1.5x to 2x the internal rim width, so a typical 13mm racing width rim (DRC ST17, Rigida Chrina) would take tyres 18 to 25mm. A wider 19mm "trekking" rim would take tyres 28mm to 38 mm. It's OK to push the width a size, but if you push too far the handling goes to pot. Narrow gets harsh, and wide starts to get wallowy on sharper corners, especially if on the soft side.
Deciding what is OK is complicated by tyres not being the size they say they are. I've measured 28mm Gatorskins and GP4S as 26mm, and 25mm Pro2Race as 27mm (both on 15mm Open Pro rims).

Re: Tri-bars and TT bikes on club rides?
Our club is any bike is OK, but don't use tribars when in a group (other than at the front or back).
It's not only the lack of quick access to the brakes, but that your control of the bike is compromised if you hit a pothole or something. We once had someone hit a pothole whilst using Spinacis in the middle of the group, resulting in a mass pileup. A broken neck for the person concerned (tho' of low severity as these things go), and someone else's frame written off.

Re: 9 or 10 Tooth on Rear Cassette
For a spare pair of wheels that can be swapped in to give higher gearing, the only option is a Capreo hub and cassette.
You can't switch chainrings without affecting your off-road gearing.
You only alternative is to learn to pedal faster. 44x11 on 26" road tyres is about a 96" gear, which is 29mph at a cadence of 100rpm.
I'm good for 25mph on a 65" gear (~130rpm) without too much trouble, and up to 30mph for a mile or so (tailwind/slope permitting), so there's reasonable scope for going faster.

Re: a bit of GPS advice, if someone could be so kind?
I think it will depend on how long ago you bought the Garmin software. When I bought City Navigator, it said it was good for 2 unlock codes, but I believe that more recent versions only came with one.

Re: Dismantling Shimano Biopace SG
The pedal should just unscrew normally, using either 2 flats on the pedal axle between the pedal and crank arm for a 15mm open-ended spanner, or a 6mm allen key socket in the end of the axle opposite the pedal. The LH pedal (no chainrings) has a left-hand thread, and unscrews backwards.
However, the pedals can get on very tightly indeed, so much so that the spanner gets damaged before the pedal moves. I'd suggest getting a bike shop to give it a go if you can't get it to move - at least they will know when to give up.
An alternative to a new chainset (rings and crank arms, but not pedals) would be to swap the chainrings for new ones. There should be 5 5mm allen bolts holding them on. There's a tool to hold the back of the bolt still if they just spin without undoing.
Note that 3 new chainrings can cost more than a new chainset, especially when there are special offers about like Spa Cycles £35 for a touring triple.

Re: XT Hub Problems - Advice Wanted
I'd look at replacing the cones & bearings in the first instance.
It's cheaper, and a lot quicker than building a new hub into a wheel.
Current XT is M770. XT M756 and XT M760 are old models, which is why there aren't many about.
M770 has replaced the previous steel axle with a larger & stiffer aluminium axle that doesn't leave so much room for the bearings. Reports so far haven't been very encouraging about the durability.
As an alternative to the Hope hub, you may like to look at the Goldtec touring hub
