At £24 is seems too good to be true - but of course it doesn't have a cache battery system, so the component prices don't need to be high.

Perhaps it is...

Re: Tip top Puncture Replacement

If normally you use just the 16mm patches (the small ones) on the Audax bike then these are good eBay deals for geniune Rema Tip Top from a reliable seller. Better than continually buying the little boxed puncture repair kits and throwing away the large patches...

50x16mm-Rema-Tip-Top-Tube-Patches + 25g-35ml-Tube-Vulcanising-Fluid = £7.75 delivered

100x16mm-Rema-Tip-Top-Inner-Tube-Patches = £8.98 delivered
25-x16mm-Rema-Tip-Top-Patches = £4.25 delivered

Rema-Tip-Top-25g-35ml-Tube-Vulcanising-Fluid = £2.74 delivered

Re: If you "can't ride no-hands".....what happens?

Closer?
I was suggesting that you have the front axle nearer to you than the front roller in a vertical plane. You'd probably want the rollers further apart.

I say all that without any intention of suggesting I've done anything unusual - others I've ridden with have done just the same.
I've been scratching my head about this for some days.

I've just done experimenting and found that when my bike steers, the footprint position of the front wheel moves forward. In fact when the steering is at 90deg, the footprint is a whole two inches further forward. This means that the effective wheelbase continually changes as I steer and balance.

This is no problem on a road - I can ride No Hands, and today I found out that I can pedal No Hands too - but on rollers it's a totally different matter.

If the wheelbase changes, the front wheel moves off the front roller, or at least moves forward on the top of the circumference. This makes the steering inherently unstable on the rollers as it is continually changing the contact position on rollers that are only 3.6" diameter. This is why it took me months of effort to get the knack of riding on the rollers and it is impossible to ride No Hands.

Therefore, if a bike can be ridden No Hands on rollers, it must have completely different geometry to mine. ie the front wheel footprint does not move as it steers.

You can normally adjust the position of the front roller relative to the front axle. I find it easiest to ride on rollers (including no-handed) when the front axle is slightly behind the roller. YMMV.

Is this a known fault? Will clear all my history out in case this has been a factor.

Three things:
1. If you load the dover TCX ride file into Training Center or Garmin Connect, is the correct total elevation gain reported? i.e. I'm wondering whether the problem is just a display issue (and the data capture is OK). If so, I have seen this behaviour (randomly) before.
2. Elevation stuff can get mucked about when riding in wet / drizzly weather if the tiny pressure holes on the back of the unit get blocked by moisture.
3. What firmware version are you running? Latest is v3.30. See http://www8.garmin.com/support/download ... sp?id=3987 for version history. There are several items relating to elevation / ascent / descent in the change history of v3.30.

(Note: If you upgrade to v3.30, you'll have to re-input all your user settings).

A bit late now, I know, but there is a way of getting any important, unsaved ride history off a 705 that won't connect to a computer properly (but otherwise works OK), if you know somebody with another 705 (or Edge 500/605/800).

You can use the ANT+ facility to send courses between the two devices.

To turn your ride history into a course, do Training/Courses/<Create New> and choose one of your rides from history. A course will be created in the 705 storage memory. That can then be sent to the other 705 via Settings/Ant+Sport/Transfer Data/Courses and later retrieved from the 2nd device to a computer. The file you retrieve has all your usual ride information / statistics and can be manually uploaded into Training Center / Garmin Connect etc.

Re: Garmin Navigation Questions

bearonabike wrote:Looking at the logistics, I want to do it all on B or minor roads. Following Mick's suggestion of planning the route through BikeRouteToaster or BikeHikeUK and uploading seems straightforward. I'm not quite a technophobe, but before I invest in the GPS unit (thinking of a 605), can anyone help with a couple of queries?

1. Will the base map supplied be good enough for what I want, or will I need to invest in the card with the more detailed maps?

2. Having the attention span of a newt, I will go wrong or miss a turn at some point. How does the unit let you know when that happens and will it automatically reroute you as some car satnavs do?

3. Presumably any of the Garmins can be charged from a car's cigarette lighter?

Answering wrt a Garmin 605/705:

1. The base map has no detail beyond trunk-roads. You'll probably want a map of some sort for visual reference and definitely for any auto-navigation you might be planning.

As mentioned above, you should have a look at the free OSM Garmin compatible maps. See: http://wiki.openstreetmap.org/wiki/OSM_ ... n/Download for options available. I'd recommend either TalkyToaster or Andy Gates' MunkyMaps (Download http://www.ravenfamily.org/andyg/maps/O ... y-UKIE.zip). You'll need to copy the GMAPSUPP.IMG file onto the 605/705 (or onto a MicroSD card) and put in a folder called \Garmin. OSM has pretty good UK coverage overall but as a community effort there will be some areas still with sparse detail and some minor roads will be missing. (It's pretty good though for free and getting better all the time).

The alternative is to purchase Garmin's City Navigator NT product. You can have UK coverage for around £30-35. All of Europe for around £50-60 is a bargain IMO, if you can make good use of it. Advantages over OSM: You'll get the complete road network down to street level and a large database of POIs (pubs, hotels, b&bs, shops, gas stations etc.) and postcoded addresses, all of which are searchable / able to be navigated to.

2. It might be worth reading the following thread (if you haven't already) which has quite a lot of information buried in it about using the 605/705 with pre-prepared long distance routes created using BRT, BikeHike etc.: viewtopic.php?f=5&t=35873

3. You'll only get a wall-charger with the 705. The 705 can also be charged using it's data cable via a USB port. So if you buy some sort of car cigarette-lighter attachment that provides a USB charging port then that should work.

Re: Garmin Edge 705 route problem

The GPXX file download from BikeHike will have the standard .GPX file extension. Just treat it like a normal GPX file.

Technically, it is a GPX file but includes a custom schema extension from Garmin - GPX eXtensions - hence GPXX. Only certain Garmin units can read this extended data. The 705 is one of them and for some reason presenting the GPS routepoint data in this format allows you to circumvent the 705's routepoint limitation (100 points)!

The GPXX format currently has a reputation for being the easiest and most reliable (but still sometimes flawed) way to get turn by turn instructions out of a 705, especially when the route is long and complex and you don't want the 705 deciding any roads for you.

Re: Garmin Edge 705 route problem

Neil Holland wrote:Wierd about the unit not recording altitude gain when on course view. Is that expected behaviour?

I have seen the altitude issue, but only intermittently. ISTR though that the unit does continue to record the altitude properly into the TCX ride file, so if you upload the ride to Training Center / Garmin Connect etc. the altitude data is there. Have you tried that?

Neil Holland wrote:Firstly it seemed that if I scrolled to my preferred screen view (with the 7 data fields I want to reference when I'm riding) it did not beep for coursepoints or bring the map to the front.

I've always had the 705 beep at coursepoints regardless of which screen is showing. Not seen your problem before. It is correct that the map page won't be brought to the front when following a TCX. That's why I tend to leave it on the map page for the ride and set up a couple of important data fields on the map page layout.

Neil Holland wrote:Will try the GPXX option and scroll through the route in right zoom.

Good idea. Doing this before you set off, it's easy to determine whether/when the 705 is going to play up on the road ahead. Forewarned is forearmed.

I have used GPX(X) on audax events, but I find it too noisy. You'll get a beep about 400m before the junction and at least one followup beep nearer the junction. This, coupled with the quirky issues mentioned, can be wearing on a long ride...

I, like Mick, prefer the simplicity and predictability of following the TCX pink line on the map page. I program in coursepoints only for certain left/right turnoffs that could be missed otherwise, but tend not to add them for "easy" junctions like t-junctions, crossroads, etc. I just use the map page zoomed in for that navigation. Suits me.

You now know about the best (only) two methods for navigating long routes using a 705. By trying out both you'll determine which is best for you.

Re: Garmin Edge 705 route problem

Neil Holland wrote:Some feed back on this TCX malarky...

Used it for my 115 round trip to Brighton and have to say I hated it... :(

Firstly it seemed that if I scrolled to my preferred screen view (with the 7 data fields I want to reference when I'm riding) it did not beep for coursepoints or bring the map to the front.
Secondly when I realised this and left it on map view, it stopped recording my actual altitude gains
Thirdly I really missed the extra information at junctions GPX routing gave... "Turn right onto Church Lane"
Fourthly a full battery ran out after about 6 1/2 hours useage. Fortunately my group knew our way home from there...

Does it drink more battery on a TCX course rather than a GPX route?

OK, so TCX is not for you.

Your best bet then is to experiment with Garmin's extension of the GPX format - GPXX. These files can be created with BikeHike (and Garmin's Mapsource?). You'll get the "Turn right onto Church Lane" information you desire and using GPXX you will not come up against the datapoint limits you've commented on previously. i.e. GPXX works for long routes. The GPXX files have the normal .GPX extension and go in the Garmin\GPX folder.

As has been point out using GPX files (of any kind) on the 705 does have some issues/quirks. You may or may not come across these with varying frequencies. As described in the OP, sometimes the GPX routing will decide to stop following the underlying road network and instead take a straight line shortcut to the next bit of the route that it understands. This can be frustrating if you're relying on the turn by turn instructions as it will stop giving them out correctly at this point. Quite often though, the routing works fine with GPXX files.

You can determine whether this "straightline shortcut" problem will happen on your own routes by checking them out before you set off. Load up a GPXX file via Saved Rides, let the unit calculate the route and then follow the pink navigation line on the map in high zoom using the joystick. As long as you see the pink navigation line following the underlying road network you should get turn by turn instructions on the road. If you see the pink line taking shortcuts, you'll know the turn by turn instructions are going to fail at that point. You'll need to navigate manually using the map until the routing sorts itself out further along (as it invariably does).

Try it on a couple of long rides to see how you get on. Tip: Turn Recalculation to prompted or off (Setup/Routing).

(Other GPX weird things you might see: If the route is circular or out-and-back the unit can try to route you straight to the finish; the unit can just freeze trying to calculate the GPX route; the mapping can just disappear).

By the way, there might be something wrong with your battery if it's only lasting 6.5 hours on a full charge (assuming the backlight isn't permanently on)...
