Get a 50cm

52 is 5mm longer than the 50 - but the 52 has 1 degree steeper head tube angle, which make it less slack than the 50 and I'm quite sure the wheelbase of the 52 is shorter than the 50!

tl;dr

52

Someone owning a 52 measure wheelbase, then I will measure mine.
Now you made me feel curious.
I could have gone 52, but choosen 50 for wheelbase and not slaping my nutsack on tt.

The wheelbase on 52 is 3.41mm shorter than on the 50

I mocked up the frame geometries in RattleCad and substracted the numbers.

953 on my pc with alpina track forks, so 950 on 52?

Yup

Thanks for the advice Thuekr, I hadn't worked out the wheelbase difference. In which case 52 sounds good - I also don't have a nutsack so don't have quite the same worries as DrEscroto

For the smaller people I would hit the Ronin instead of PC for more exciting angles and shorter wheelbase http://shop.goldsprint.de/product_info.php?info=p1024_goldsprint---ronin-track-frameset.html

Yeah sure, it doesn't look as incredible close up but basically just tape over then scalpel and score round the dropout.
Will take some tonight.

I tried covering up some logos but I had a few issues with air bubbles (wide pvc tape) but I guess with more patience it could work. I also bought a different kind of tape with which I will try to recreate your back tubes covering, I hope you don't mind.

Here is a recent pic of my TC

I'm also thinking about getting a paintjob (red) for it but not yet sure whether I want to spend the cash on just a different color

Cool go for it dude, I just used electrical tape and pulled it round so it kinda stretched and overlapped itself.

Gives a ok finish nothing special, is looking a little worse for wear after putting up with 20 miles a day in recent weeks.

Your tc looks real nice, you could always just raw the frame yourself. Thats kinda like a new colour. That my plan when I get bored with mine.

The only thing I found when I covered the whole bike with black tape was that when I took it off it peeled a little bit of the logo's away so now there is a gap in one which is a little annoying.

This is it blacked out

Anyone ever fit a rear rack to their FXE/ Pre Cursa? Any recommendations?

This.

Ronin is a little expensive compare to Precursa but the geometry is not too dissimilar to the MASH Parallex.

Which is a rebranded Colossi Cheeko http://www.colossicycling.com/products/bike-frames/129/cheeko-track

PreCursa does CX

The ronin looks like a good buy, though yes it is steepee in price especially considering price doesn't include headset/seat post/postage.. Might be a tad steep for me.

Looks really nice in that pic though, what size is that one? And thanks for the advice guys!

Looks like their 59

Just pulled the trigger and finally ordered a pre Cursa. Looking forward to building it up once it arrives and riding.

Anyone has any advice on good chain tensioners you have used.

don't bother with chain tensioners, just tighten the wheels correctly

@chickenleaverpuller - I like the idea of keeping your Sainsbury's shopping list in your rear wheel spokes.

I would, but I'm currently attempting to turn my Precursa into a Fixed TT bike and I don't think my Lidl list would help the aeros.

Any chain tensioners experience. Just pulling the wheel tight ain't enough.

I love the MKS chain tensioners but have heard they don't fit Aluminium drop outs?

Anyone's experience would be great b

And what size bottom bracket to use with a 47t chainring 130 BCD

For what?
