New MTB

New MTB

I got lucky today! One of the men at running club offered me his old mountain bike for parts to repair the one that fell off the back of the car. I was expecting an old hunk of metal so was pleasantly surprised when I went to collect the bike. It’s a nice little entry level full suspension machine. Sure, it’s heavy and a no-name brand but it is in good condition (and it was free). The rear derailleur is bent so it catches the wheels when in the granny gear, and the rear derailleur and brakes are sluggish (probably just a matter of new cables). But these should all be easy to fix. It could also do with a new set of tyres (but they are consumables anyway).

So this is the current state of my normal MTB. It’s looking a bit sad. I don’t know whether you can see how badly bent the handlebars are from the photo. I’m hoping to go to RecycleWorld tomorrow at the rubbish tip to see whether there’s a suitable parts bike there for next to nothing. I’m particularly keen to get a rear wheel and now a rear derailleur so I can fix up both MTBs. The rest of the parts are relatively cheap and I have been offered a set of brake levers / brakes by another running friend.I am very keen to get this bike working again because I just love riding it. There will be races where it’s better suited to the course than the full suspension bike, which loses a lot of power in the suspension.

Who knows, I might soon have three bikes: my road bike, full rigid MTB and full suspension MTB. Then all I need is a second set of clipless pedals for the new MTB and I’ll be on my way.

A couple of rest days

I’ve taken the past two days off training because my sacroiliac joint is giving me trouble. I whipper snipped (I don’t know the non-Australian-slang term for this activity) the borders of my lawn yesterday for the first time since May. It only took half an hour but it did enough damage to make walking painful so I wasn’t keen to try running. My partner has a similar back injury to me and she later told me that she doesn’t whipper snip for the same reason.

This evening I replaced the brake cables on my mountain bike. That felt like quite an accomplishment after riding all year without brakes.

As 2012 draws to a close, my partner and I are taking stock of our current life and financial situations. Our lifestyle has changed drastically the past three years and the dreams we had back then are vastly different to those we have today. We are starting to feel more certain about the direction we would like to take for the next half decade and, without saying anything more, 2013 is going to be a huge year of exploration for us.

I’m going mountain biking tomorrow morning. The physical exercise will do me good.

Upgrading my MTB part 1

Unlike the update to my road bike, my MTB update will have to happen in stages.

Upgrade 1 complete including new white grips

I’ve slowly been installing the new components and accessories I bought for my MTB. Normally I’d be keen as mustard to get them all installed to try them out. But I’ve not been able to ride and won’t be able to until the weekend at least so I’ve been taking it slowly.

New vs old

I started by replacing the tyres. The old set had a lot of miles on them and were better suited the road. My new sets are an off-road set that promise to give me better performance now that I’m using the MTB as an MTB instead of as a road commuter (which is how I was using it when I bought the old tyres in 2009).

The old cassette

New 7-sp HG-50 cassette

I replaced the old 7sp Shimano HG40 cassette and chain with a 7sp Shimano HG50 combination. The old cassette was totally worn out and filthy. And the chain was destroyed. At one point I had let it rust after riding in mud and not cleaning the bike while it sat in the garage for about 12 months before the Adventure Race Australia event earlier this year. Since then I’ve just been dropping heaps of lube onto it and ignoring it creaking. I can’t wait to feel how good the bike moves now that it has a new chain and cassette.

The filthy crankset

Disgusting rear derailleur

The derailleur wheels can spin again

To say the bike was filthy is an insult to filthy. My old MTB had not been properly washed since I bought it. Sure, I’d hosed it down after Adventure Race Australia in May and the Tre-X Off-Road Duathlon in July. But that was all I did: hose it. I didn’t get in an wash it properly or remove more than the outermost layer of mud.

The crankset and rear derailleur were a seemingly permanent shade of brown, rather than the black and silver they should have been. The jockey wheels on the rear derailleur didn’t even move anymore because the mud and grass were blocking them. I’m sure I’ll notice the difference in my first ride.

New tyres, pedals, chain and cassette

I can’t wait to ride the beast now that it feels like a real bike. I have new grips to replace the sticky mess that I used to have to hold (great thing I learned about the hairspray trick because otherwise they would never have got on). I also have finally got clipless pedals on my MTB rather than the flats I used to use.

My next upgrade will be my brakes and brake levers. I was thinking about getting a set of Deore levers and brakes but might just start by replacing the cables and seeing whether that fixes the stickiness that I’ve currently go (I have to push the levers back out to release the brakes). Though I still might just replace the whole lot if I find a spare $100. I used to run Deore on my old MTB and loved the groupset. Eventually I want to upgrade my whole groupset to Deore but it’s easier to do it bit-by-bit on my MTB because the brake and gear levers are separate.

Anyway, I can’t wait until I can hit the trails on the MTB. If my back keeps responding to treatment it should be find by Saturday, which would mean I could get back on the bike next weekend (I want to leave a week between the pain subsiding and getting back into training because the SIJ takes 2-3 weeks to heal after the pain ends).

The Tiagra groupset is sweet!

1996 Trek OCLV with new wheels and groupset

I realised I haven’t yet shared my joy at having my bike upgraded with a new Tiagra groupset and Shimano 501 wheels.

Tiagra 10sp double groupset

The bike originally came with an 8-speed Shimano Ultegra 600 groupset, which was top of the line at the time.

The bike went into storage in about 1999 only to come out about 8 years later when Mum started to ride it. She eventually replaced the cassette with a Shimano HG-41 MTB cassette so that she had a granny gear.

When I started riding the bike last year, I replaced half the groupset with an 8-speed triple ring Sora groupset from a 2005 Giant OCR3.

But now it is adorned with a full 10-speed double ring Shimano Tiagra groupset.

Shiny new 10sp cassette and rear derailleur

It’s going to take a while to get used to the new gear ratios. Especially because I don’t have any double-up in the middle of my range like I used to. But once I’ve ridden a few times I’ll be set.

I even got new brakes with the new groupset. No more panicking when I ride too fast.

I can’t wait until next week when I should finally be able to take my sweet new-ish ride out to see how she handles.

Bargain!

Tiagra 4600 10sp groupset

Tiagra 4600 10sp groupset

With the death of my 2005 Shimano Sora 8sp triple front derailleur I have embarked on an exciting new cycling journey: a 2012 Tiagra 10sp double chain ring groupset journey.

Avanti Plus in Fortitude Valley has a whole groupset available for $AU450, which is only $70 more than it would cost me to buy the groupset from my usual UK-based suppliers. For an extra $200 I am getting my old groupset stripped, new groupset installed (including cables) and new bar tape. I also get a free service to adjust the gears after my initial ride.

While I could have bought the tools to install the whole lot myself, I decided that the price for installation is reasonable compared with the cost of buying the necessary tools. The swap will be taking place while I’m away sailing at the Whitsundays so I just have to drop my bike off in the city on my way to the airport tomorrow morning and collect it again on my way home on Saturday afternoon.

Bring on the 200km Audax Australia Bedrock 1 ride next weekend when I will effectively have a brand new bike.

I do hope, though, that this is the last big spend for my bike because I’ve been bleeding money into cycling since getting back into these past months. Still, it’s been a lot cheaper than buying a new bike … and I love my Trek OCLV frame.

Death of my front derailleur

The dead front derailleur

I was excited to cycle to work this morning because I have a new set of wheels on my road bike. Alas, it wasn’t meant to be. My front derailleur seems to have died a sudden and mysterious death. It won’t shift at all anymore. When I disconnected the derailleur cable the shifter seemed to be working so I believe the problem must be in the derailleur itself.

I suspect there is a bolt that has come off the side of the derailleur because there is a hole with threading inside it that is currently empty. I don’t know whether or not there ever was a bolt in there because I’ve never checked. But at this early stage of ‘investigations’ I’m fairly sure it’s worked loose somehow.

I am running an 8-speed rear cassette and derailleur with a Shimano HG-50 chain. I’m not keen on replacing the whole drive train yet because that would be expensive. I also currently have a triple chain ring and front shifter on my bike. I can’t find any suitable components online because the Shimano Sora series is now only available in 9-speed and 10-speed, while the only 8-speed triple derailleurs are all designed for flat-bar bike gearing systems.

I guess in this instance I am off to the bicycle shop to find out what my options are. I wouldn’t mind switching to a double chain ring on the front but am concerned the shifter might be expensive to replace. At least this gives me an excuse to replace the bottom bracket and crankset because my smallest chainring is rubbing against the frame protector and the whole crankset is sitting at an awkward (non-parallel) angle to the bike.

Given that I couldn’t cycle to work this morning, I might try another walk/run this evening.

Overkill for commuting?

Perhaps this wheel is overkill for commuting?

Perhaps this wheel is overkill for commuting?

Whenever I see people cycling through the city and suburbs on their race wheels, all I can think is ‘What a w**k**r’. I know it’s harsh but it seems a bit pretentious to me to be riding around the city on carbon fiber deep rims or, worse, full discs. However, this morning I had to become one of those riders … and I felt a little embarrassed about it. I felt very strongly that riding to work with a Zipp 530 on my bike was a bit overkill.

Do you see the problem?

Do you see the problem?

Unfortunately, I had no choice. Last night I was almost home when I heard a big ‘bang’ from the back of my bike. I didn’t know what it was, initially suspecting the bottom bracket had finally packed it in. On closer inspection (I was actually cleaning my bicycle) I discovered a broken spoke. After much swearing I grabbed my trusty laptop and researched options for replacement / repair.

I concluded that it was probably more economical for me to replace my wheel set than to get the spoke replaced. Why? The wheelset on my bike is the original 1996 wheelset that has not had any maintenance so I anticipate that more spokes will pop. And a full new Shimano 501 wheelset only cost me $137, which is relatively cheap compared to the price of repairing one (or more) broken spokes.

So that’s how I ended up cycling to work this morning on a wheel that is certainly overkill for commuting. And why I can’t wait until later today or tomorrow when my new wheelset should arrive.

Total: 12.9km cycle commute each way to and from work.
