I have a few bikes - Charge Plug fixie, Dawes audax, a Giant TCR Advanced, Boardman hardtail, also an omafiets (Dutch granny bike) - which I ride depending on mood, purpose and weather. My preference is for road riding, but I also enjoy the velodrome and infrequent offroading.

Home is the New Forest, a rural part of southern England with superb cycling. I've also worked and commuted in London. I've done some short tours, also tend to plonk the bike on the car rack when I go away. Doing this, I've cycled quite a bit of western Europe.

I started out riding several years ago to lose weight, these days its to maintain fitness and for fun. I've been maintaining my own bikes (mostly) for years, and recently got a bike mechanic qualification. I'm also a motorist. In real life my background is computer software, I run my own company which is pretty much a part-time gig these days.

comment Is BMC PRO MACHINE SLC01 2009 compatible with Ultegra Di2?
In theory, yes, although you picked an expensive way to upgrade. The fly in thei' ointment could be internal /external cable routing, might also need to compromise on where you house the battery. I've kinda decided to do this upgrade myself (one day), except when I go for it, I'll replace the whole bike.

comment Which bottom bracket do I need to replace crank on a Trek FX 7.1?
Hmmm, that bike is still in production but they don't mention the bb on their spec sheet. For sure it will be English - Italian threading is basically confined to Italian high-end road bikes. You might need to measure the bb that is in there to get the exact size. Shimano offer several groupsets at different levels of quality, check their web site (Tiagra is middle of the road).

comment Torque for front caliper bolt.
that number certainly sounds reasonable to me (I have a carbon bike myself but have never messed around with the fork). But the first tool I bought having got the bike was a torque wrench!

comment 9x4 spoke pattern
I can't see any technical advantage either, I'd put it down to appearance. I mean, all the normal rules wrt lacing still apply.

comment Air Pressure on wheels
Possibly. It would be interesting to see a graph on how the weight of a cyclist affected the area of tyre surface in contact with the road. I know that load can have an effect with cars, but car tyres generally run at far lower pressures than bicycles.

comment Can't shift to gear one or two
If the chain is jumping, or coming off the cassette, you could say it is dangerous in that you could unexpectedly lose traction. If not, then as you say, you're just losing some gears.

comment Air Pressure on wheels
Pressure does affect performance - you only need to imagine the extremes to see this. However "perfect" pressure would happen on a per-tyre basis.

comment Having the fork blades aligned
To the best of my knowledge, this kind of work is done using a clamp and some brute force - there's no science going on. If it were me, I'd have a go myself

comment Can't shift to gear one or two
It sounds like you have adjusted things, but not correctly. Set the limit screws first - you can just use your hand on the derailleur to do this, you don't need to faff around changing the gears. Once they're set, leave them alone and concentrate on the tension.

comment Replacement crankset for Shimano SG B 52/39?
If you look on Shimano's (US) site, check out the FC-2300 which is an 8-speed 52/39 crankset. The only reservation is that the 2300 group is quite some way down Shimano's product range....I'm not sure how good it is, basically

comment Replacement crankset for Shimano SG B 52/39?
yep....you're probably also getting the impression that you're being forced to upgrade by the bike manufacturers. And you are, it is a bit naughty. If you're running an 8-speed cassette, then 8-speed rings will be absolutely fine, if you can find them.

comment Replacement crankset for Shimano SG B 52/39?
3400 and 3500 are both 9-speed systems, I believe. You might be able to find a Tiagra part to suit (that'll probably be the FC-4500, from around 5 years ago) but you'll have trouble finding anything in any of the better groupsets, where they left 9-speed behind > 10 years ago I think. Also, 10-speed cranks will be a lot easier to find (I think the current Tiagra is 10-speed), just not a "perfect" fit.

comment Replacement crankset for Shimano SG B 52/39?
By standard, I mean that your requirements can probably be satisfied by a number of parts. If the cranks don't exist in the Sora range, try looking up the ranges - Tiagra, 105, Ultegra, Dura Ace. The only thing you need to be aware of is that cranks are built for a certain speed (e.g. 10-speed) and the manufacturers recommend matching this speed with the number of gears on your cassette. The trouble with this question is that it sounds very much like you're looking for a product rec, and such questions are off-topic on this site.

comment Replacement crankset for Shimano SG B 52/39?
Your bike sounds pretty standard to be honest. Your best bet is to look at the Shimano web site, I would be surprised if you can't find everything listed on there in the USA. Certainly 52/39 is a standard combination.

comment Help for wind noise
Surely the problem with this is that if you block the noise of the wind, you also block the noise of traffic? Or are you in a traffic-free environment?

comment SRAM xx1 1 x 11 drive train very noisey
My first guess would be that the derailleur isn't adjusted properly.
