If we're talking just weight, a pair of Marathon Plus tyres weighs 1320g more than my tyres - that's 2 Xiaomi pumps-worth (Contental Gatorskins, with better puncture resistance than Marathon Plus). However, in the real world of pounds rather than grams, the true weight saving is to be found in...

I received mine OK. It was also ordered on the 7th, delivered on 12th with no problems. Can't see if it was Hermes, sorry.

I meant the mini-pump is for punctures out in the wild, not for everyday use. I should have qualified that, sorry. For a pump in the garage/house, a track pump is even cheaper, and much quicker, and it's got a gauge: https://www.wiggle.co.uk/lifeline-essential-track-pump However, buying two...

Call me crazy but a Crank Brothers mini pump weighs 1/3rd of the Xiaomi, at 40%-ish of the cost, and is the same size (20cm long): https://www.tredz.co.uk/.Crank-Brothers-Gem-Mini-Pump_70322.htm?sku=215578&utm_source=google&utm_medium=cpc&utm_campaign=google_shopping The 'normal' pump also...

and > Am I the apparently the only one here who can read and speak German, now that is worrying , the standards of modern education.........surely there are a few others with a proper education with languages as well? I'd call that off at a tangent. Choose your words and criticism carefully...

Have done so, thanks.

Welcome, AndyBike. That Scott is an interesting one - I've never noticed it before. It's full-on mix of mountain bike and city slicker: - really good full suspension setup, but also - pannier rack, kickstand, mudguards & lights I quite like it. A proper 'do-anything' bike.

I advise you to eat spam. Hello admin, hello? ;)

Ah, I saw those, and thought they were just for mucky mountain biking only (to stop the muddy grunge going in). But you'd recommend one to keep the grease from wandering off?

Yup, with moving parts, it's defo not fit & forget, especially in that, er, most sensitive of regions. :eek: From the instructions... Every 100 hours or once a year: 1. Disassemble the seatpost from your frame. 2. Unscrew the adjuster bolt and slide out the coil spring. 3. Clean the seatpost...

Having had a quick read of the installation instructions, that's the preload. I'll be setting that as directed (about 1/3rd compressed). I'm a fair bit heavier than 200lbs, but I'll still give the standard spring a try, as suggested by vfr and sjpt. No point spending if the standard one works.

Thanks Phil - purchased! Early Xmas prezzie. I see the extra springs on eBay. I'll investigate further.

Just in interest, are they any good for tarmac uneveness? The roads round here are degrading rapidly, and we haven't even hit the winter frosts yet... Oh, and where do you source the different springs from? Cheers...

V sensible. The other advice is to avoid wearing jewellery/watches/rings that might just accidentally short stuff out, if you're tinkering with a charged battery pack. (I've only ever shorted one old-school pack out, when I was younger, but it was quite exciting, and stuff happens quicker than...

Spot on! Anyone who has a heavier bike than mine is an idiot, anyone who has a lighter one is self-indulgent. A 'normal' ebike plus a Tagalong / trailer bike might be better long term, and probably about the same weight (see note above ;) ). As your child gets older they can have their own...

Cool and Eeek in equal amounts! At 38mph it's going to hurt when you hit the ground. Consider body armour, gloves and a full-face helmet if you don't have them already. And don't blow that runny nose...

Those E-Plus tyres are almost a kilogram each, by the way. And people worry about battery weight. Tch! With that weight and the amazing puncture resistance results, maybe they don't actually have any air in them. ;)

Good point, Wheezy. Re-reading, the small print says: > All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs. and > Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load. [Edit: you beat...

Doh! Knucklehead. I'm surprised they don't quote for a pair. To help the simple folk. :)

I can't see the 60W figure. The touring/ebike tyres all seem to be in the 17-33W range, with summary for that tyre saying: Rolling Resistance: 27.4 watts which looks like the 60PSI result. Am I simply misreading the page? (wouldn't be the first...
