Rebuilding a Wheel

[Anil Bhambhani]

 

Hi All

Had the misfortune of getting struck by a speeding motorcyclist on the HAL airport road. I got away with minor injuries but my rear wheel has been badly damaged. Pic attached.

My cycle is BTwin Rockrider 8.1, wheel specs are given below:

Rockrider Comp 32 hole rims by Rigida Hub JT D041/D142, 2 mm stainless steel spokes Sealed bearings. Disc Brakes

I approached Deacthlon for a replacement they only have this is in stock

I am not too happy with the wheel and would like to see if I can get the wheel rebuild using the original hub. BOTS has the ALEX DC19 RIM 26" on its online store

http://store.bumsonthesaddle.com/collections/rims/products/alex-dc19-rim-26

Requesting advice if it’s a good idea to rebuild the wheel. If yes, who would be the best to do it.

Thanks to all in advance.

I had a similar accident a few years ago and dented my front wheel. 

Theoretically, someone could bend it back into place methodically, but more than likely you will not get the original manufactured shape of the wheel.

Also the bending and straightening of the rim may make it more vulnerable when you ride over a large pothole.

I would buy a new wheel. 

BTW, I have been knocked down twice by those "other" two wheelers. We have to protect our rights on the road.

From the pics of both the wheels, I can see that the rim has bent sideways, not inward (towards hub). That should be possible to rebuild with the same rims. Having said that I would go for a 36 holes rim/hub for an MTB rear any day. If you are riding only on road, 32 is fine though.

I had one wheel, road front, with a dip inward and I rebuilt using Shimano 105 hub and I was able to fix the dip. I built without truing stand, using the bike fork itself. Rear will be a bit different though as you have to take care of the offset.

If you are considering discarding the rim, I think, it is worthwhile trying to rebuild with fresh spoke yourself once.

Hello there Greetings, 

 

I’m 28, 5’2 and weigh 57 kgs. I've been cycling for about six months now. I've had a slow start, from couple of days a week (20km for a ride) to every alternative day. Now riding 20km in total every day to office and back home. I run occasionally over the weekend not more than 5km, or go for a long ride on average 50km - and rest for two to three days even when I'm comfortable riding the next day. And also I don’t ride when I have sleepless nights.

 

My regular diet is like :

 

2 Dosa’s or Idly Vada for breakfast

Regular South Meal or Sandwich with Milk shake

2 Dosa’s for dinner with or without Milk shake

 

Ginger tea or lemon tea three to four times a day.

 

About the same time when I’ve started cycling I gave up on Non-veg and processed / canned foods, strictly no sweets, drinks, snacks and refined sugar. I've lost almost 6kgs by now (I was 63) and my physique looks proportional and bit stronger than I ever was. But by the outlook the people who knew me earlier compliment me that I’ve reduced to my frame.

 

It didn’t bother me at first but now I’m concerned with my weight and eating behavior. All the fellow cyclist I come across look better than me.

 

Am I over doing it? Or eating less than needed? I’d appreciate your suggestions.

 

Best,

~ Vasu

Ultimately your decision but I would not rebuild the wheel with the same rim or spokes.  I suggest that you get new rim, new spokes and retain the hub etc unless they have some signs of obvious damage. DC19 is a pretty strong rim and a good choice for your build. In case cost is a big concern, get jaymex brass nipples and local steel spokes once you determine the length.  In the end, it might even be more cost effective to get a new factory built wheel so check with your nearest LBS.

For the longest time in the bike workshops we did, across several corporates, I kept telling people if you cycled you can eat anything and get away with it. It was a very bad advice as I later realized :)

Cutting processed food, animal products, dairy, etc are all steps in the right direction. It might be better to simply increase the intake of fruits and raw veggies. This will make you a better rider too. A lot of athletes have seen much faster recovery times after this change.

One uncle I know who runs 10 kms daily has reduced his run time from 58 mins to 45 mins now. He did a sub 2 hour half marathon at his age which is really commendable.

So what did the magic? Their's is a Punjabi family and they haven't taken milk for the last two months let alone any non-veg. He did a 9 week course with THAC in Mumbai. They introduce you to the possibilities with your health by mere change in the intake week after week.

Now this is working for a lot of people. I have noticed a lot of positive changes after increasing fruit intake. You can #TryItForYourself. Bear in mind fruits must always be had empty stomach. Nothing around them for at least an hour (before or after).

We will hopefully get some workshops done on the subject of sports nutrition if possible as we see that processed foods (sports drinks, gels, etc) are on the rise amongst people most wary about health.

A good start point is this video on health if you are interested.

As for the weight don't worry so much about it. If you do things right it will all fall in place. If you really care about numbers then take care of inches rather than the kilos :)

Hope this helps,
Mynk

May I ask why? Is it the risk factor or time factor or cost factor or complexity?

Back in my childhood days when the rims were steel, we used to ride till rust makes holes. Once on my return from school, my front rim went inside my friends stand. This is a common phenomenon in crowed rides (remember, the first cycle day in Cubbon park had so many such mishaps). In my incident, the rims were wafer thin, worn out as brake corroded them. So, it just mangled without breaking a single spoke. My friend and I thought for a while, stranded in an open stretch of road without any houses or shops. Then, we used hands and legs to straighten as much as we could. I continued using the same wheel for many more years to come.

The trend that I don't like is that people are making it an expensive affair to own and ride a bicycle. A bicycle should easily last for 20,000 km without a single replacement, except a pair of brake pads and tubes probably. Yes, you read right, not even a tire. I still use my stock tires on my hybrid which I bought in 2010, though I have swapped the front and rear. Except for a broken rear axle, I haven't spent a rupee. Last month, I changed the chain and freewheel too, but they were picked from someone after he was advised to discard by service shops (https://groups.google.com/d/msg/bangalore-bikers/YcVxbU2wyY0/41U9cSgVJ3cJ). He apparently had a btwin sport 1 cassette, an MTB 7 speed freewheel and a chain, all for discard. I happily picked them up as I knew they would become useful down the line. They are as good as new for me and I have no doubt that they will run for the next 10,000 to 15,000 km easily.

I have never given any of my bikes for service, not even for the first free service offered. I would never clean my bike even after a ride in rainy slush. I had to open the bottom bracket once (https://groups.google.com/d/msg/bangalore-bikers/5PPa2R88eMw/-nDqjau3eTUJ) which was damaged by my washing in a canal after a slushy half iron triathlon in Nagala in 2012. I had to wash as I had to load the bike in car.

Sorry, a rather lengthy post. But I wanted to drive home the point that we don't need to shell out so much money for bicycle, specially on maintenance. Having said that I spent 13K last year on building a single speed and I felt like a fool at the end ;-)

[Opendro]

Staying on the cost, my hub cups are worn out. I don't want to replace the whole hub just to replace the the cup. Has anyone seen cups being sold separately?

[Opendro]

A bit of googling shows that I wouldn't be getting them loose. So, better bet would be to pick someone else's discarded wheel/hub :-P

Hi Vasu,

Not sure what you mean when you say 'other cyclists look better than me'. If you are taking about loss of muscle mass I would like to share my experience in this regard.

After I started cycling I started looking lean, lost some fat and after some time I started to loose muscle mass. I had been going to the gym (on and off). If I kept up the gym routing I would maintain my ideal weight and I used to loose 3-4 kgs if I stopped going to the gym. The 3-4 kgs consisted mainly of muscle mass. From then on I try to balance off aerobic activity (cycling and running) with weight training.

From the nutrition point of view it is generally advisable to have some carbs within half an hour of an intense activity. Having a banana after a ride/run rather than having at other times makes much difference. This input I had taken from a session by a nutrionist.

Please try the second part first and if that still does not give satisfactory results I suggest some strength-training.

Regards,

Vivek

Both fitness and body shapes are very subjective terms, so they mean different things to different people. Many bicyclists strive for that reed thin 'raisin' look; muscular legs with thin to skinny arms and no extra fat anywhere. This is ideal for biking, as it would give you power to weight advantages which are wonderful for climbing and endurance.  Anybody who gyms a lot and then stops will testify to muscle loss, but biking in itself doesn't cause muscle loss; however, it only really puts the focus on the legs. It's therefore good to do some training for core strength.  As long as you feel strong and good, you are generally ok. The human body is fully capable of indicating whether it's ok or not; just learn to develop a better feel for what your body says.  Please avoid crash dieting and/or food-fadders and quacks completely. I've personally interacted with people who've adopted weight loss remedies and food substitutes and suffered the consequences, including extreme weakness and fainting.

Regarding comments by others, please learn to take that with a lot of salt; be what you want to be. People will always have things to say, too fat, too thin, too lean etc and that's not necessarily useful to you.  Have fun riding your bike, and more strength and confidence to you!

@Shankar : have decided to get the wheel rebuilt at BOTS using the DC 19 rim. I want to use my original Hub as its a good hub with sealed cartridge bearings making it near maintenance free.

@Opendra : will retrieve the rim and may be someday use it to try and rebuild a wheel using a spare hub. But that would need to wait till I learn the basics of building a wheel. At the moment priority is to get the bike back on road.

Thanks for sharing your experiences and all your references.

At first I started to lose fat yet my weight remained the same and I was fit, lean and happy. Now that I lost weight further (muscle mass) that's when I pressed the panic button.

I never was this active before I arrived at Bangalore, around the same time my food habits changed and cut down meat and sugar. Guess it was the biggest source of energy.

Never used to take anything before or after a ride / run, except water, always sticked to my timings. The fear of discomfort and puking stood my way.

I may not go back to have meat again, I guess more fruits can compensate, and to four meals a day from there. And add up some weight training.

Thank you!

Best

@Opendra - you are right in that cycling is becoming expensive. The cost of spares as quoted by Decathlon for my bike are  

Rear Wheel                        2500

SRAM X7 F&R shifters       4490      

SRAM X7 RD                     4690

Crank Set                           8990

Kind of difficult to digest. buying an imported bike is easy but if you use it regularly getting good maintenance and sourcing spares is a headache.

[Ali Poonawala]

Hi folks
Just an extension of this thought process.. Though not exactly related to OP's query, so apologies.. 
Sharing resources , rather than all of us buying expensive tools, is coming back in lot of enlightened communities
Can we start such initiative ?
So to give concrete example.. If Opendro has wherewithal of building a wheel.. Anil goes to him and learns to do from him at mutually convenient time. Compensation may be agreed to.

I am not trying to take things away from LBS or boutique shops like BOTS, but empowering cyclists to do things by themselves,will raise our cycling ethics and ethos to another level..

Any takers for madcap musings ?

My thoughts ...

In general, there are 3 groups of cyclists -

1. A few will not do any mechanical repair of any sort and would rather take the bicycle to the LBS for even minor tweaking.

2. Most can change a flat, tinker with the brakes / deraileurs, adjust the chain, etc.

3. A few don't have to visit the LBS at all.

The cost of tools for group 2. is minimal and well worth the investment. Besides, you can save time and do the repairs at your convenience.

As a member of group 2, I do not have the tools or the expertise to true a wheel, replace a hub, or cassette. However, since these repairs are fairly infrequent, I haven't felt the need to learn or acquire the tools.

I don't mind visiting the LBS once a year and believe keeping your LBS in business is important.

However, one accident can change the whole schedule and add expenses as well. With more traffic and the same space, congestion is increasing and it becoming a hassle and risky to ride a bicycle. I don't see any solution to this problem!
