Oooo - that Lezyne FAQ is useful (should've looked there before!). Also says "Why won't GPX files give me turn by turn navigation? Turn by turn navigation (TBT) is only written in TCX codes, so if you're using a GPX file it will not produce TBT. Also, it is important to note that not all TCX files produce TBT, only certain ones do. For instance, Strava TCX codes do not have TBT written in them. They will only produce a bread crumb line like a GPX file. Our GPS Root website produces TBT and also produces TBT navigation in their TCX files."

I was assuming I could just import a GPX to the Lezyne Mini (from an Audax organiser or the GBmapOmeter site I use for route planning) and off I go with TbT. So instead, can I assume the Lezyne GPS Root website or Ally app will do a conversion from GPX to TCX to add the TbT data?

Thanks for all the thorough answers, guys. Will get myself a Mini

Fantastic - thanks for taking the time to do the test, Paulatic. (Sorry for slow reply - been offline at the outlaws for a few days.)

To NA: The manual tells us functionality is same across the Micro, Mini, Macro & Super. Also, I can't see the TbT software being any different in the XL, and Paulatic confirms that too. And yep, I'd thought to bring a small power bank if/when I have another go at a 200k ride .

Cheers - two last questions (more general ones):
- Is average speed computed from data only when the bike is moving, ie. ignores times when stopped briefly?
- I've read that while riding, GPS devices (not specifically Lezyne) often record "rogue GPS points that need cleaning before analysing post-ride stats". Is that also an issue with the Lezynes? I'm used a simple wired Cateye to get my elapsed time and average immediately - upload & cleaning would be a faff for everyday rides.

Happy New Year

Thanks folks. Nice to see the manual - which confirms functionlity is same across devices (although focuses on how they work with the phone app, not if they work without it). And v helpful to know the turn-by-turn instructions can be edited at home pre-ride.

I much prefer to carry just my tiny Nokia brick on a ride where I roughly know the area or am with others. If I'm solo in unfamiliar territory, I'd take my smart phone but with GPS off to conserve phone batt life.

So as I understand your replies: I can upload a route at home, head-off without a smart phone and get TbT nav, but it won't reroute me if off-course, so instead I'd just retrace the last few 100yds and use the breadcrumb thing to get back on track (which sounds fine).

Paulatic wrote:The mini like it’s bigger versions when linked with your phone will give you TbT. If you go off route it will tell you so and at this point I find moving to the breadcrumb and you can see yourself getting back to the line, or not.
TbT when the route is created with Lezyne is usually not too bad but I’ve found some imported tcx files to have a lot of nonsense in them and at which point you find following the breadcrumb is a lot more useful.

Thanks, Paulatic. Helpful tip on switching to breadcrumbs.
And if I leave my phone at home, you're saying the Mini can't navigate by TbT, or can't navigate at all? The latter at least would be a show-stopper.
And any limit to the length of route you can upload?

Does anyone here have a Lezyne Mini? I'm wondering what it's like for navigation? My routes are always planned ahead, so am not bothered about the lack of mapping. I understand it does 'turn-by-turn' navigation, eg. "turn left in 150m". I'm particularly wondering:

- What does it do if you miss a turn?
- Does it deal well with complex junctions? (Eg. road bears round to the right but my route continues directly ahead onto a side road)
- Can it navigate independent of a smart phone, using just a pre-uploaded route? (Sometimes I’ll leave the phone at home, sometimes carry it with GPS switched for good battery life.)
- Is there any limit to the length of route you can upload?

Thanks!

That kicked off a great discussion - thanks, guys

On the Eurostar regs, it just says "2 pieces of luggage (up to 85cm long) + 1 small piece of hand luggage". So I guess that's the length of the longest side. No stated restriction on the length of other sides, but can't imagine they'd be happy with an 85cm cube! It's a useful note from bikepacker on the nylon holdall - needed to count the 2 panniers + tent as one bag, but thin & strong to pack down for the mini tour.

On the Airnimal folded size, the manufacturer website doesn't seem to say, PH states 85x90x29 and the bikefix website has "83x80x25 [typo 83x60x25??]. For extra protection you can also put it in the Traveller Case: 87x66x35". Hmmm. Bikepacker: Do you know your folded dimensions? Also, detail from any more owners would be great!

And I'm 6ft. But like a short-reach setup.

Will do some research later on Terns, Moultons, Rudge, ......

However I recognise Bromptons are expensive and may well be out of some people's budget which is when the misinformation is brought up. A bit like the Rohloff hub. I am fortunate I can afford or could afford a Brompton at the time and also Rohloff hubs. As I say not every one is in this position so cheaper options may well be necessary. It would have been helpful if the OP had indicated their budget.

What are your top & bottom gears, Ivor?

And on budget, less than £700ish on eBay would be good. That'll get me a vgc Joey, haven't looked at others yet. The way I see it is that it's also an investment, expecting to get a good chunk back with a sale down the line, especially on a sought-after model.

I'm after a touring bike that can go hand-baggage to the Alps etc by train. It'll just be used a few days a year, so will look second-hand, likely eBay. Essential to me are: folds down to less than 85cm max dimension for Eurostar & TGVs, can take a rack for panniers + small tent on top, lowest gear less than 25" (or can be adapted), and can be (un)folded in less than say 20mins with little practice. From a quick first look at Bromptons and Airnimals, I wonder if it'll be the low-enough gearing in a used bike that'll be tricky. What would you buy that fits the spec?

Thanks, guys. And nice techy video. And nice shiny bike, Nick - maybe even dripping oil on David Cameron

What's the advice on where to clamp a bike to a cycle maintenance stand and the direction to align the clamp? Obviously I want to minimise bending and twisting forces on the frame (titanium) and seatpost. Intuition tells me maybe clamp to the seatpost, keeping the post roughly vertical, but not sure the intuition is reliable . Thanks!

Thanks folks - I'll gamble on just a pair of SH51s. No use for another set of pedals.

My feet are now unclipping from my Shimano PD-M520s when I pull hard, even with the spring tightened up. It's worse on the right, which is the side I unclip for a quick stop. There's also some up & down movement when I pedal, and sometimes a little rattly. Is it more likely to be the pedals or cleats that are worn? Can I get away with just replacing the cleats? Thanks!

Thanks, bikepacker - would be ideal. Do you have any details or a more precise location? I can't see anything on google, UK Campsites, or OS maps.

(Re. trespassing, personally I wouldn't camp on private land without permission, and anyway I find farmers are usually happy to accommodate a small tent & trust we'll be gone in the morning with no mess. Rules for common land vary, and also common application of the rules. But that's all off-topic anyway )

Does anyone happen to know of a good wild camping spot near the M48 Severn Bridge? Either side is fine.

(On route from SW to S.Wales, and campsites add 10-15 miles to the route. And wild camping is fun anyway )

Thanks!
