GT Edge Aero - Silver/Chrome - HHSRBRGRLOLWTFBBQ

I'm sort of left with a bit of a quandry how to proceed. Basically because not much of my current stash is compatible and/or is previous generation kit. I don't have any brifters - all my stuff revolves around DT shifter setups, namely either 6-speed Shimano indexed or how I've converted it to 9-speed indexed with a 10-speed cassette minus one cog and 10-speed Dura Ace DT shifters with the end position locked off. To move to brifters I think I want a minimum of 9 gears to make it worthwhile. I'm pretty sure this needs new calipers to work well, also.

So I think I have options:
1) New Shimano 105 10-speed. This allows me better future options if I want to build a more modern bike and gives me all the gearing I'm looking for, but I think it'll look out of place on this frame (I'm thinking specifically the crankset). I already have a 105 derailleur and 10-speed block in stock.
2) Dura Ace 7700 9-speed. I think will look great and is period-better but a lot of $$$ for something I'm probably only going to use on this bike.
3) SRAM X0 off my mountain bike could be all the LOLS with the risers. Probably not. Or maybe. Also can't mix and match the shifters/derailleurs here because the pull ratios are different.
4) ??? ideas plZ

And then that brings round the issue of wheels. Only 8 of the 9 gears will fit on my current wheels without hub mods and they're 10 years older than this frame. I think that rules them out. The HED disc will only fit the same but it's a screw-on freewheel so it can't have a cog taken off to fit.

Whatever way I look at this it's becoming a bit of an expensive build which I'm struggling to justify.

I have a full DA7800 groupset excluding chainset...

if 8 fit, 10 should too.. only obscure early 7400 dura ace had a proprietary 8sp system, the rest is ≤7; 8-10 (1mm spacer for 10); 11≤

(if i'm not mistaken)

Isn't X0 exact actuation? You could use brifters with that

Current wheels are for 5/6/7-speed, not 8. The cassette wheel is a 126mm spaced Uniglide hub with a 7-speed Hyperglide freehub, which fits 9 of the 10 gears off a 10-speed Hyperglide cassette. I have the 10-speed Dura Ace downtube shifters and just use 9 of the clicks. It's all a straight swap to get more gears in a narrow frame. To take all 10 gears it just needs the wider freehub body and a longer axle.

The HED is a screw-on freewheel so that can't be modified, and I'm pretty sure it's only wide enough on that side for the 7-speed freewheel or it'll hit the stays.

X0 9-speed is 1:1. What brifters were you thinking? The derailleur doesn't index correctly with 105 9- or 10-speed shifters, for example.

Ah, any Sram 10 speed. I didn't know you were trying with shimano ones

Hold on, this wasn’t part of the plan...

Two sets?! That's some nice development, my money is on whichever cassette that will get this out on the road sooner.

what the make of your car? cant identify

Honda

Mk1 Insight?

what the make of your car? cant identify

Yep, Mk1 Insight.

74mpg on the 40 mile round trip to pick them up in case you were wondering!

So jealous. Always loved the first gen Insight and the Mike Burrows wheels.

Placeholder parts. I think this means no backing out now.

Already looking strong!

Wow.

^^ Strong

Looking good!

I think there’s room to get 28s on, but the 23s there are pretty close to the bottom of the fork. 25 might be more realistic.

So, so good.

I'm a believer now.

somehow the curve of the forks is out of place.. giant once would suit better imho. burrows seatpost?

Straight blade forks would be ace alright. Build is coming along so nicely though!

Looking great! Needs a more modern chunky stem though imo

A 3T pro chrome

ITM Eclypse

Something of that ilk

Something like the kinesis Wedge
