Time Trial / Time Trialling / TT

Going up doesn't lose your chain though, only the chain moving sideways loses your chain.

Your bike will be lighter...

Lucky for me @dbr has a workshop that I will be using later. Anything else I should grind off?

The flared bits on your brake pad holders.

The pin should just unscrew.

No fun.

Ta, saves a trip. It's riveted, but came out with a pair of pliers.

Get rid of those grub screws too

All sorted, thanks hive mind!

Anything else I should grind off?

At least nine sprockets you could lose.

Sounds like you've already got rid of the pin but ideally you want to keep it close to the top of the chain really. We've not had anyone say that before though, what size ring is it?

Hear, hear.

It's a 53T from a 10S Double.

Any one riding the Lea Valley 25 on the E1 on Sunday? I am marshalling.

@dbr @cjr and @skinny

Dunno if these have been posted here yet, super expensive, but surely the bigger ones would be alright for you fixed tt'ers

met a lad on a Pearson fixie, asked him about it and said he didnt know much about bikes, said he'd just bought a 66t ring as it would "look cool" it's amazing that kids coming out of the education system have no concept of gearing.

Is it? I’d say it’s pretty neiche knowledge outside of bicycles and the industrial revolution.

Is there a chain long enough to run a 66t chainring with a rideable gearing?

66/16 should be fine

Unless you have super long stays, 66/18 (~97") is going to need links taken out of most track chains. If you want town bike gearing, your problem is really finding a 26T fixed sprocket, because if 110 link chains don't fit there are always Wippermann's extended e-bike versions, 1E8 comes in lengths up to 136 links

super expensive

Hipster tax much? That's about 50% more than the machinist wanted for doing a much more complex one off 72T.

pretty neiche knowledge

Obviously not as niche as knowing how to spell niche 🙂

I'm sold. I need one.

Who wants to help with my crowdfunding?

Yeah, is that really what £250 worth of extra metal looks like?
