MBK Trainer – Fixed Gear Version 2

I don’t recall if I’ve mentioned this before but the 80’s Raleigh frame that I used on the first fixed gear is now “dead”. What happened? Well I’m not quite sure. It’s viewable in one of my Cyclist POV videos, where you can see I’m riding along and all of a sudden the rear wheel locks up and I come to a stop. It’s happened before but never that violently and never just riding along. I realigned the wheel and rode on, but after getting to my destination I realised the wheel no longer looked straight… The rear triangle looked bent. A few second opinions later and I had concluded it must be the end of that frame.

Note: At no point have I actually checked the frame alignment with the available tools.

A few weeks have gone by and now I have version 2 up and running. Version 2 was found on eBay for the small sum of £15. Naturally the colours caught my attention and I had to have it. As luck would have it, nobody else was interested in it and I won the auction for the starting bid. I have to say the seller of this frame has been an absolute pleasure to deal with – possibly the best seller I’ve dealt with. He emailed me as soon as the auction ended and asked if I wanted some further postage quotes and after looking around found one for £4 cheaper than quoted. Unfortunately he hadn’t checked the PayPal transaction and booked the delivery for the wrong address. Nevermind, he got straight onto the courier and had it changed. The courier didn’t even come and collect it and instead it had to be dropped off at the post office and sent from there. I was updated on the whole process and never left out. I wish all sellers were like that!

Anyway, the new build! The frame is a two tone, pink and purple, MBK trainer. I haven’t been able to accurately date it however I’m leaning towards an early 90’s date. Lugless, oval tubing and CRMO – I really like the frame. It has its fair signs of wear and it the colour apparently disgusts come people but I love it. It’s just my size and it’s so light.

Straight away I removed the headset from the old build and fitted that to the MBK frame. The old Halo wheelset went in perfectly, as did my old black stem. This is where things change. Instead of the flat bars I wanted to fit a set of drop bars in black with some all black brakes. I’m only running one brake, yet still decided to fit two levers. Why? Because I like the riding position! Finding the all black bars took a lot of searching on eBay as most 25.4mm clamping bars are for silver in colour for old road bikes! It was worth it though, the black bars and brakes make the pink stand out even more.

When it came to the bottom bracket and crank I had to get something new. The Raleigh uses 26tpi thread and a cottered axle, where as the MBK frame uses a standard 24tpi thread. I have a few spare cartridge bottom brackets that I could have used but something new was more appealing. I decided to head to VeloSolo and take a look at their collection. I opted for the 107mm Stronglight bottom bracket and crank set. It looks amazing and threaded straight into the frame. The Raleigh used a 42 tooth chain ring (I believe) where as the Stronglight uses a 48 tooth. Combined with the 14 tooth sprocket I’ll be getting more top end but hill starts will become a bit tougher. I’ll see how I get on with it and if it’s too tough I’ll swap out the sprocket to a 16 or 18.

The tyre clearances are close but I’m going to swap those out for some Michelin Krylion Carbon when I get some spare cash! (Those tyres are brilliant – I’m using them on the British Eagle in the wet). Apart from that I’m 100% happy with the outcome. The bike feels like a perfect fit and everytime I look at it I find a massive grin creeps across my face. It’s definitely not everyones style. What do you think?

British Eagle – The Eagle Will Soar Again

*typical evil genius laugh* It lives. IT LIVESSSSSS!!

Doesn’t she look nice! It hasn’t been an easy ride, and it’s probably cost me around £300 for everything but I would stand by this build and say it’s better quality than a brand new £300 bike! From a battered, patched up and seized bike (minus the wheels) to a wet weather / winter ride using quality parts. I’m pleased!

I left the last post explaining how I’d made a mistake with the forks. I’d forgot to check the length of the threaded portion and when I went to install them I quickly discovered the problem. My freshly powder coated Reynolds forks were virtually no use. I contacted Mercian but their response wasn’t too promising. Instead of adding mroe thread with a die they were suggesting a process of removing the old steerer tube, welding/brazing in a new tube of the correct length and then repainting the forks – sounds pricey! I started looking about for dies so I could attempt the cutting myself and found one in China but before I clicked the submit order button I decided to try someone else. The fabrication company that we use at work were my next port of call. I popped down for a chat, explained what I wanted and I was offered a few alternatives. They could use a die to cut more thread in, but there wasn’t a guarantee it would work because they had no way of telling if the tube had been hardened. Alternatively they suggested using a lathe but the layout of the forks made that a logistical nightmare. The last option was to bore out the threads on the upper bearing race. It made sense but I wasn’t quite convinced it would fit well enough.

Luckily eBay came to my rescue and I found a pair of beautiful yellow Columbus forks in exactly the right size – for only £15! Cheap, but there was a reason for that… they had a stem (cut off) seized into the steerer tube. I fancied my chances so bought them. My plan of attack was simple:
– Penetration spray
– Filing flats into the exposed stem to grip with an adjustable spanner
– A little “persuasion” from both side with my trusty hammer
– Fire and ice cycles
The plan may have been simple but reality wasn’t. Days passed as I tried each method daily but the stem wouldn’t move! My last resort was the selection of drill bits at work. A stem made of an aluminium alloy should be fairly easy to drill through so it should be a quick process, right? Well yeh, it was. I initially drilled down the centre with a 17mm drill bit which ultimately created a lot of heat but the stem was still stuck. I followed that through VERY carefully with a 21mm bit. The tube itself has a diameter of 22.2mm so I was really looking out for the side walls, trying not to damage then. Millimeter by millimeter I at the stem away until I thought I was hallucinating. As I looked into the tube I could have sworn part of the old stem had been on the right as I’d started drilling, now, at this point, it was on the right. I tried to drill again and this time the portion ended up at the top. IT WAS FREE! A light tap from the underside and it dropped right out. No damage to the forks at all!

That evening I rushed home and got the rest of the bike put together. I swapped out the crown race on the forks and fitted them first (I need to get a couple of silver spacers to match the headset) and then fitted the NOS replacement 3TTT stem and the original bars. On went the brake levers and I adjusted everything to my riding position before fitting the new brake cables and taping them in place on the bars. I’ve chosen to use some yellow cloth bar tape for a more “vintage” look but I’ve double wrapped the bars for more comfort. The only thing I want to change now is the grubby white brake hoods…

Everything is now tightened down and adjusted. She’s ready for her maiden voyage. I’m looking forward to it (I’ve also treated myself to some Shimano R260 Carbon Shoes 😉 )

British Eagle – Nearly There

I am so happy with the potential outcome for this bike. Considering the state I got it in, giving up on it because everything was seized and almost throwing it away, I think it’s turned into a beautiful bit of kit.

So what’s changed? Well the colour for a start! I decided to ditch the old metalic blue and go for a classy black number. It might not be the right choice of colour for a winter bike but style sometimes comes at a cost… I found some new Reynolds forks in the same style and set about stripping the paint… only… I couldn’t. The original paint was so tough that a good few coats of Nitromors barely even touched the surface. Sanding was an option but being impatient I decided to take a trip to the powdercoaters and get it sand blasted. My aim was to spray the bike. It would be cheap and easy but would it last? No. It had to be powdercoated. Black was still on my mind however something else caught my eye….

MOD Green! The finish, the colour, just wow. I love it.

Digging through my drawers I managed to find some of the original parts for the bike. I still had the old handlebars, bottle cage and brake levers so I was going to need a lot more components to complete the build.

Groupset: Shimano 600 (Ultegra) I set about searching eBay for parts, mainly looking for a modern STi groupset but also keeping my eye out for older sets. I really don’t like downtube friction shifters and I really did have my heart set on a shiney new set however at £70, I couldn’t turn down this set. It looks almost brand new! Nearly all the decals remain and the only imperfection is the shiny scuff on the drive side crank arm. What’s even better is the downtube shifters are indexed for the rear derailleur so there shouldn’t be any more guess work in shifting. Everything fits the frame perfectly.

Handlebars & Stem: I decided to look back over the old photos for this one. I wanted something close to the original in terms of the stem but back then, I really didn’t know much about parts. As soon as I glanced at one photo I recognised a badge. Zooming in, I was certain. The stem I’d snapped off was a 3TTT stem! Doh! I ran a Google image search which brought up some early 90’s catalogues which confirmed my thoughts but also revealed the identity to the weird shaped bars. The stem I needed was a 3TTT “Record” and the bars I have are 3TTT “Forma” bars. I looked through eBay and found a few high priced stems but at £80 a pop I was put off, until fortunately, I found a NOS “Record” stem at just £25.

Pedals: I’ve given the old Look pedals a good clean and they seem to work still despite the paint flaking off. I’m going to give them a go and if they don’t work out I’ll buy some Shimano SPDs.

Seat & Seatpost: What I really want is another Brooks saddle! The reality is I’m spending too much money so for now I’ve settled for the old mountain bike saddle I had on the fixie. The seatpost I went for, one of the cheaper used items on eBay (£15), is also an old mountain bike model. It was in a right state when I got it. The alloy was scratched, dull and embedded with dirt but hours of polishing with the Dremel has brought the shine back. It fits perfectly into the seat tube now with a brand new stainless clamp bolt.

Wheels: Well I already said I had the Mavic wheelset, and I did buy a spare hub to rebuild the rear hub and a new set of Shimano skewers but what I’ve actually ended up fitting is a Campagnolo wheelset. One of the sellers I follow, who is fairly local, and often has nice bike parts listed from house clearances, just happened to list a few 700C wheelsets. I ended up winning the Campagnolo set for just over £20 and also a “back up” Alexrims set for £10. Both wheel sets are in great condition but the Campag are the nicer of the two. They’ve been wrapped in some Michelin Krylion Carbon tyres, which again, were a pretty good buy at £25 for a pair!

Headset: I actually still have the old headset but it seems to be missing some parts. After having a look around I went for a Tange headset. It was reasonably priced (at £15) and looks to be a good quality bit of kit. It was easy to fit but here’s were I’ve run into a problem. Numpty here didn’t bother to check the thread length on the forks when buying them and they’re 10mm or so too short! I was all set to get the bike on the road last weekend but this has really thrown a spanner in the works. I’m currently looking for somewhere to add some more thread (I’ve tried Mercian but they haven’t replied yet…) but if worst comes to worst, I’ve found the correct size die on eBay and I’ll attempt to do it myself. I’m kicking myself at this rookie error.

Everything else is ready to go! I don’t know when I’ll get this finished off but looking at what I’ve achieved – I will see it through. From a £10 scrapper to a beautiful commuter. For what I’ve spent I could have just bought a brand new bike (all be it a cheap one) but where’s the fun in that?!

Keep an eye out for the finished bike. Hopefully it won’t be a long wait.
