Re: ICE quest adventure front axle/hub advice

The front wheels use removable axle bolts. The front hubs use 2 sealed cartridge bearings with a support tube between them. The support tube stops the inner races from being crushed inwards once everything is tight. The axle bolt is then pushed through the bearings from the outside, through the hole...

Re: converting a bike to use an IGH?

It's possible but it depends on the back dropouts on how easy it is. If the dropouts are vertical then you're into a fixed distance between the BB and the IHG. If you're lucky then the chain will fit exactly with the correct chainring/sprocket combo. If not then you can use a half link and/or chain ...

Re: UK to Cape Town is it viable?

I'd check the journals at "Crazy Guy On A Bike".
Somebody must have ridden that way and left a record about it there.

Luck ............ :D

Re: Gear ratios, in inches

.............. But I wonder if there are any other factors involved? For be it was information on how to spin faster. As a kid I learnt that pros cycled at 100 rpm, so I should. But that didn't tell me how to achieve this. I tried the trick of dropping a gear and trying to keep the same speed. But ...

Re: NCN5 at Wilmcote Warwickshire

Looking at the area in OS maps and Google satellite maps shows it may be possible.
Go south along Church Rd, turn left into Manor Dr, then a (farm) track will take to a bridge over the canal to pick up the NCN5.
How passable that route is will need wheels/feet on the ground.

Luck ....... :D

Re: Lowest Traffic Route?

A lot will depend on how much extra time you have to meander up quiet lanes. With only two weeks then you're pretty much locked into an almost direct roughly 1000 mile route. With 4 weeks you can meander a lot more and up the distance to around 1500 miles while still doing a shorter daily distance. ...

Re: Hypothetical desigin

FWD has been tried in tadpole trike but it's never been very successfully implemented. Back Wheels are easy because they don't need to turn. Front wheels are much more complex because you need some form of CV joint in the kingpins. Then you want it to tip which adds at least another set of UV joints...

Re: Upgrade 11-28 to 11-32

The other question to ask is will you cope with the new cassette. To up the size of the largest sprocket without adding another sprocket means some of the other sprockets need to be altered as well. Check where the changes are in relation to your most commonly used sprockets. If you suddenly get a v...

Re: Gear ratios, in inches

The easy one to remember is ......... If you can spin a 100" gear at 100 rpm then you'll be doing 30 mph. For that if you know what cadence you want to spin at and you know what speed you want to hit then you can work out what gear you need to do that. If you spin at 80 rpm and you want to hit ...

Re: 20” wheeled e bike

Have a look at the Hase Pino Steps. It's halfway between a "normal" bike and a full cargo bike. You can put a 5 point harness on the front recumbent seat to strap your child in place. Plus the child is in front of you, so always visible. Fitted with the twin legged kickstand it should be s...

Re: Average mph difference

I can still remember when I first got my ICE trike. It had the "standard" 15"-100" derailleur setup. I was doing around 100-150 miles per week. But any uphill slope still had me crawling up it in first gear. Then I went on my first long tour and upped my mileage to around 250-300...

Re: Average mph difference

My average on the flat is only around 12 mph. Add the trailer full of camping gear for touring and I'm a couple of mph slower. Add any hills and my average speed can be cut in half, the exact amount depends on how steep/long they are. A trike needs a different mindset. It's not about getting up hill...

Re: Will a Rohloff tensioner cope with double ring

When it says 10 links, it means 10 full links. So it will cope with a 20 tooth difference between rings. I'm fine running a 38/55 double. I think the best way to set multiple chainring up is to use multiples of 1.136 as ring spacing. That sets a front change as almost exact rohloff gear spacing. So ...

Re: Road Bike chainring comparability

So as long as they are 10 speed ring, I see no problem unless they have proprietary bolt hole spacing.. Each chainring will be 2mm bigger. So you will have to move the front derailleur up 2mm to match, that's easy. I cannot see the increased size of the inner ring catching on the chainstay, so no pr...

Re: Home built disc wheels

I've not done it but I've read about it on the net. With rim brakes the only real option is a lightweight rigid cover wired/zip tied to the spokes. With disk brakes you can also use the rim to hold the cover in place. A stretch fabric (lycra) cover can be held in place by trapping it between the rim...
