Re: Town bike with carbon belt drive - any suggestions?

fenmanctc wrote:If the attraction of belt drive is low maintenance, I have fitted my Trek Soho ( early with Alfine 8speed) with a full Hebie Chainglider. This almost obviates chain wear the need for frequent lubing,and keeps clothes clean. Had to change front chainring from original to one compatible with Hebie’s sizing spec, but it works a treat. Have drilled a small oiling port on upper surface.Can be fitted to most IGH bikes, but ain’t cheap. BTW the Soho is a cracking town bike, but has an aluminium frame. Spec now reduced to Nexus, I think.

The Hebie Chainglider is £35-40 depending where you buy it. I wouldn't call that too expensive.

If you could say what sprockets and belt you had whether CDN, CDX or CDX:EXP this would be very helpful.


In the OP case, Gate CDN 120t, to a 46t/22t driving a Nexus 8.


Thank you this helpful.

From my understanding of the Gates spec of belts and sprockets, CDN is your basic level i.e. commuting leisure riding typically in cities and urban areas, not extreme cycling. The rear sprocket and front sprocket are manufactured from plastic and the belts are robust but not of the higher spec belts which I believe have Kevlar in them, but I might be wrong.

For the higher spec CDX/ CDX:EXP range Gates make the rear sprockets in stainless steel rather than plastic and the front belt rings in 7075 aluminium and their belts as I mentioned above are tougher, containing Kevlar I believe but I might be wrong about the Kevlar. In any event they are much tougher than the CDN belts. So because the CDX / EXP components are more durable they can be used for off road, snow, ice, sand, extreme expedition riding, winter riding in cold temperatures.

I suppose you could use a CDN set up all year in all conditions but it might not last as long as a CDX:EXP sprocket and belt set up.

My belt drive bike came with a plastic rear sprocket which I changed for a stainless steel one. I still have the plastic front cog, but am trying to find a CDX:EXP one in the same size. I did get a CDX belt but at present I am still using the CDN belt until it wears out.

I think if I was going to be frequently riding through mud, gravel, sand, salt of winter I would put the CDX components and belt on. I shall be putting the CDX belt on when I go on tour and will hopefully have found an aluminium 7075 front ring by then, but I think the front ring despite being plastic will fair better as there is less wear on it simply as it is larger.

If my bike's belt and sprockets got covered in mud like in the pics I would be hosing it off. A fully enclosed guard would be nice, but I don't currently see one on the market. Not to say a partial one couldn't still be fitted to help keep the belt clean.

HTH.

Re: Obesity epidemic and our addiction to oil

Vorpal wrote:While there are some very good points in this thread, I think that it is a problem in our society to judge people by how they are appear. It is not possible to determine whether someone is healthy or fit by body shape. To attempt to do so is unreasonable. What someone weighs or should weigh is between them and their GP or medical consultants.

Fitness makes far more difference to health outcomes than weight or BMI. And while there is a correlation between fitness and weight, we vary as individuals. Perceptions of 'overweight' and 'obese' are culturally driven, and not entirely supported by medical evidence. Yes, obese people are at higher risk for some conditions; no argument there. But studies have shown that people who are 'overweight' have the same health outcomes as people who are 'normal' weight. more info viewtopic.php?f=49&t=121499


So what body shape are you, potato or runner bean?

I totally disagree with this apologist ill informed view. It is what has got most people so FAT in this country. An NHS that is bulging with fat staff failing to tackle the elephants in their surgeries whose LOVE of sugar and carbs, gluttony and addiction has got them where they are. Of course you can tell how healthy some one is going to be by their body shape, skin, eyes, hair, etc. First and foremost, fat people are likely to be type 2 pre-diabetic or diabetic caused by them troffing industrial quantities of foods laden with sugar, stodgy starchy processed foods, bread, pasta, potatoes, pizzas, crisps, chips, buns, sugary fizzy drinks, alcohol, all the horrors you KNOW you shouldn't be eating or drinking and doing zero exercise. They will also get out of breadth just getting off the couch to go to the fridge, panting and wheezing. It is depressing seeing all these types of people when out shopping, hanging onto their shopping trollies containing mountains of processed foods, pies, chocolate, crisps, biscuits, ready meals, etc.

It is decades of government and NHS "expert" advice that has told people to eat a LOW FAT HIGH CARB diet that has created the epidemic of fat people we now see. It's as if the food companies, big pharma, doctors, the NHS and government have all been complicit to make people who are unable to educate themselves or are just bone idle to become fat to keep them fat because then they can spend the rest of their lives on drugs such as metaformin, allowing them to eat more of their crap foods, continuing to use the NHS for their increasingly frequent and more serious ailments brought on because they are fat! It is a scandal.

It doesn't help when many doctors, nurses and NHS staff are themselves fat. If the appearance and weight of many NHS staff is indicative of their organisation's healthy lifestyle policies and programmes then they have totally failed. Is it any wonder that the general population is also potato shaped. It is not hard to work out that it is sugar and carbs that are the problem and the killer and a lack of any exercise. Cut these out, do some fasting and exercise and the weight will literally fall off. Educate yourselves and have some self discipline.

All the rest you talk about is simply window dressing skirting around the huge elephant in the room which is diet. The greatest weight losses can only be achieved by a change in diet. Yes there are fit and healthy thin, slim, svelt, toned people who work out - go to the gym, cycle, run, swim, walk, hike, play sport, golf, what ever floats your boat, but the common denominator is that we don't shovel lots of sugar and carbs into our mouths.

It is not people's addiction to oil, but addiction to sugar and carbs that is killing them.

Re: Sp dynamo hub re-bearing

I was considering one of these hubs, but in the end bought a Son 28 which has operated faultlessly so far in 2 years of use over about 10k miles.

that is Australia though, not clarty UK roads/conditions.

FWIW I suspect that one of the things that may wreck belts in the UK is wet followed by freezing; if moisture penetrates the fabric parts of the belt at the sides, then freezes, I suspect this will cause the belt to delaminate much faster than normal. Worse yet if the belt is used in this state I think it will be likely to (literally) fall apart. If it is cold enough, the belt may stay damp/frozen in use, unlike many (most) other applications.

He's ridden tens if not hundreds of thousands of miles touring around the world particularly in South America. He knows what he is talking about. He has spent considerable time and resources accumulating many many miles of experience under his belt. He uses a Koga touring bike with Rohloff hub and belt drive. AFAIAA it has never let him down either the Rohloff hub, Gates belt or any other component. So I consider his real world experience very helpful and worthwhile unlike some who comment on set ups they haven't used or don't understand.

But still in a full working order, a 150+ odd miles last week, with a few high speed dashes.

Anyone else find that MAINTENANCE BACKFIRES :? (Nb.

You need to get a better bike preferably one that does not have derailleur gears nor chain, nor rim brakes. Maintaining and servicing these types of primitive bikes if you ride a lot of miles every day in all weathers is a real PITA. It is depressing. Buy yourself a bike with internal hub gear or internal gearbox with a belt drive and disc brakes. You will genuinely have a low/zero maintenance bike except oil changes to the gear box. enjoy cycling again and have so much more free time to do other things. Save yourself a small fortune in not having to frequently buy replacement derailleur components, chains and new wheel rims and wheel builds every few hundreds/thousands miles when they are worn out. Derailleur bikes are bad news when it comes to riding every day in all weathers in all seasons.

One thing's for sure, most of the outdoor go to places, AONBs are going to get trashed this year, even worse than last. Can't wait for foreign travel to open up again to relieve the pressure on our own country's fragile beauty spots. Chavs and scum can jet off to Spain, Greece and Ibeefa.
