So today I planned to change around my cycling time to morning instead of late nights (thanks to the rain, the traffic and pollution I breath in in spite of the buff I wear, and in general wanting to have more of the evening for myself and family).

So did not cycle yesterday, set the alarm for 5 a.m., laid out my cycling gear, and went to sleep (around midnight). Before that having topped up air in both tyres and recce'd in my Storme a new 30 km route with a lot of nice rolling climbs.

Bottom line - I never even heard the alarm, forget shutting it off. And actually landed up getting up later than normal (near 8 instead of 7-7:30 ish).

So here's my first morning cycling session update -

One pretty simple way is to stand the bike up with the valve tube on bottom dead centre, and mark the ground there. Then push the bike forward, preferably while sitting on it and stop at the next bottom dead centre. Make another mark there. Measure gap between marks to get correct circumference.

I actually tried with a string as well (my daughter struggling to hold the other end, then cello taping the other end).

Your idea seems a lot easier.

P.S. I just realized the significance/rationale of why you mentioned "preferably while sitting on it"

There is a small comb sized tool which you can get on ebay. It has small teeth which go into the space between the links. The idea is that they should take some push to get into the space between the chain links. If they slot freely then it means that chain has stretched due to use and is to be replaced. I saw the cycle repairman use it to tell the customer that his cycle chain still has some life left. No need to change.

This can be easily done using a steel rule. Check out the below video that explains this method.

So today morning I DID manage to wake up (5:20 a.m.) and was on the road by around 6:30. Had decided to nix my recced route because the surface was really not good in a lot of places, plus it was in-city, which meant traffic chances even early morning.

And headed off to the mecca of fitness junkies, arthritic geriatrics, and MAML's (middle aged men in lycra) - Pashan, Chandni Chowk.

One major advantage of riding in the daytime immediately became apparent within the first few kms - I could actually see what was going on in my cyclo-computer without having to check the stats at the next stop.

I remember having tried Chandni Chowk with some biker buddies with new cycles many years ago, on this same cycle of mine, and remember having had to get off at the last really steep stretch towards the end.

Happy to say that today many (easily close to 10) years later, I manage to make it to the chai tapri at the end, huffing and puffing with the final effort, in the last but one gear (1-2), but did not stop and did not get off.

I guess the 5+ years now without cigarette smoke in the lungs has paid off.

Some stats:

Dist 15.66
Max 35.40
Avg 19.80
Time 47.02

Had a cup of tea, whatsappped some buddies who were still waking up, and then started back. The ride back was easier and faster. I also discovered that I actually like doing flyovers and there is a technique of building up momentum (and shifting to the correct gear) just beforehand such that you crest the flyover with minimal effort and then build up momentum again downhill for climbing the next one.

Dist 16.82
Max 44.90
Avg 25.20
Time 38.27

I like this route and think I'm going to make it my regular daily ride one. Only I should be on the road at least an hour earlier (saw many bikers returning while I was doing the to leg). Will keep a log of these stats to map improvement and slowly try to extend the ride onward till NDA gate (wonder if its still allowed or have they closed that road off for civilian traffic now). And from there try to do more and more non stop before stopping for a break. As it is, this was about 32.5 kms and about 85 minutes of ride time. So with a 5 minute breather and tea break it should be a good 1.5 hour workout before office.

Some lessons:

1) Gear not shifting down from 2 to 1 when climbing and chain under tension. This is a new one.

2) The left bar end suddenly loosened and rotate on the hand with me putting my weight on it.

3) The cyclo-computer mount is loose and rotating when I try to adjust the angle of the screen while on the move. Also, when flying over speed humps (the advantage of a heavy steel frame and steel rims ) the cyclo-computer starts getting dislodged. I had to press it back into position a couple of times. A friend of mine had one of his fall of and get lost in a similar manner.

Any remedy for the above? A rubber-band around the clip of the computer which attaches to the mount plate somehow?

That is a pretty decent slick mtb tire. Had (have) it for almost 6 months and ~1000+ kms. Very durable and good tires.
And a decent deal; I paid 1200 odd for it last year.
Finally went to Phadke Haud today. Found an excellent alternative in Continental Contact II. (http://www.amazon.com/Continental-Co.../dp/B00HPS8NW2)

At 300 Rs per tire, its an excellent deal as well. Unfortunately there was only one in stock. Will go next week to get the fitting done. Will update the thread with my feedback.

On a side note, the weather in Pune is perfect for cycling now a days!!

Thanks for your guidance.

Alright, so I started the "restoration" of the Hercules Top Gear Ezy DX yesterday. I should've taken a few pictures to show you all a before and after picture for a few morale boosting replies, but alas, I forgot.

Here's what I got out of Day 1 of restoration:

I dismantled most things:

1) Grips
2) Shimano Grip Shifters
3) Bell
4) Removed the handle bar from the T Stem
5) Front derailleur
6) Rear derailleur
7) Front brakes
8) Rear brakes
9) Seat
10) Seat post
11) Front brake levers
12) Rear brake levers
13) Tyres

I also removed most of the rust from the new shock absorbers and a host of other parts with steelwool and WD40. Must say, http://www.team-bhp.com/forum/motorb...ted-parts.html (Removing rust from chrome-plated parts) was very helpful.

Now, I am stuck. I do not know how to remove the rear cassette as it is from a company called Starlit and I would rather have a Shimano cassette down there.

Any pointers?

I do not have the special freewheel removing tool that I see most people use on YouTube and the other jugaads don't seem to be applicable for this cassette either.
Any pointers?

Where are the rear brakes?

Got the Bianchi serviced. Certain 'consumables' were replaced.

The gears were fully disassembled; cleaned; degreased; lubricated and put put back again. Reassembled.

Working perfectly now. Shifts are perfect. I'd say that the bike is performing better than new.

Man; things do get better with time- specially after the run-in.

The cost of this tune up job - a meagre 200 bucks. Knowing a good mechanic does help. My usual fellow does know how to set the gears right.

Another day; another perfect tune-up. Very satisfied with the services offered by Surinder.

_____________________________

On a short ride today; touched 65 KMPH. This Bianchi does go quite fast; 65 was achieved very, very easily.

The fastest I've gone yet is 68 KMPH on my 2012 Montra- that took a LOT of effort. I was very tired after reaching such speeds.

Maybe a short while later I'll see just how fast the Bianchi can go with stock gearing.

Very satisfied.

Can you please provide the details of your mechanic? I assume he is based in Pune.

Alright, here are a few pictures that should help anyone who is trying to help me!

Here is a picture of the old steering fork, notice how much it extends beyond the race on top of the head tube:

The Bicycles thread-old-steering-fork-1.jpg

And here is a picture of the new steering fork, notice how much more it extends beyond the race on top of the head tube

The Bicycles thread-new-steering-fork-1.jpg

I am assuming a lathe workshop can help me sort out the fork length issue?

And here is the picture of the race on top of the head tube, definitely needs changing I believe?

The Bicycles thread-head-tube.jpg

Also, I was looking around on the internet as I will need to change the Quill stem on the bicycle. I found a Quill type to threadless type stem adapter.

For those who don't know, this is a Quill Stem.

The Bicycles thread-quill-stem.jpg

This is a Threadless Stem:

The Bicycles thread-threadless-stem.jpg

And this is a threadless adapter:

The Bicycles thread-threadless-adapter.jpg

Anyone knows where I can get one of these in India? They are available in on amazon.com but not on amazon.in.

Also, I was looking for the grip shifters. On my small check online, I noticed that there aren't many choices online in India. Amazon.com, on the other hand, is pure heaven.

That said, I found the decathlon website listing some BTwin Shifters. Are shifters interchangeable? Can I use a BTwin shifter for a Shimano derailleur for a Starlit cassette? I plan on getting things functioning first and then getting things specific.

I still don't know how to remove the cassette from the rear wheel. :(

To remove the cassette from the wheel, you will need mainly two tools - chainwhip and lock-ring tool. You being a DIY guy, there are ways to do this without these special tools as well. Youtube has many videos. Here is one.



Good luck with the restoration
