First Fixie Surly

Hmm woops, well wasnt lots of money. Got the 42t first think id run 42/18 but then after a little reading around seemed this might be to low a gear, duno what peoples thoughts are on it. Is only going to be used for 5min ride to and from uni.

Plus another reason for downsizing chain-ring n not up-sizing sprocket was as the wheel is at the front of the dropouts as it is so not sure the current chain would fit onto 48/19

If it's only being used for a 5 minute run you should be fine with whatever gear you choose.

Ignoring tyre size 42/18 should give you about 63", I'm running 44/19 which is a little lower still, I find it a good balance of acceleration, speed and comfort, it's good for light trails and Monday morning hangovers.

Sounds good, just want a good gear for ease of skidding and to make pulling away easier. Plus being a student monday morning hangover gear sounds good haha.

Cheers

1 tooth difference is a big jump despite how it sounded.

If I were you, I'd simply get a different cog with the 48t as it's a lots less hassle, or if you insist on running 42t, get a 17t instead of the 16t.

Plus with 42/16, there's a likelihood of needing to shorten the chain.

More skid patches too :-)

Yeh, only 3 skid patches for 48/18 and 42/18 isn't much, guessing I will go for 48/19 or 42/17. Maybe I should have done some reading up before buy the potentially wrong cogs :(. Oh well they were only cheap and will give me a taste of what ratio I want to run.
Cheers for all the advice guys.

A few more photos, have been doing abit of DIY with different handlebars and adding some leather bits to the toe clips, all abit DIY but I reckon they look alright.

Think I prefer ridding the bulls though, think il have to find something cool to do with them to make them look abit better though
