29er Thorn MTB?

[Hamish]

I have similar sliding dropouts on my Woodrup built by Kevin Sayles.  They work just fine but so does the thorn BB which is so simple it is hard to see how it would get broken. In fact you don't really need to use a special tool to adjust it. 

All systems have their advantages and disadvantages and I think you get used to wha you have.  My main worry with my sliding dropouts is that the sliding bits with the slots are made of aluminium and may be less strong, that I could strip a thread when tightening them and that they seem to cantilever a long way out to the rear which looks as if it could be subject to a lot of stress on a bumpy road.  I am no engineer so I am sure that the worries are unfounded......

Nah! You want one of these 29ers are so last week.

I think anything like slidey dropouts looks relatively robust these days if compared to carbon frames and "stupidlight"  disposable components. Doesn't make it strong like a Thorn though  

Now if only they'd made a Penny-penny instead of a Penny-farthing. That would have been some steampunk mountain bike on 60 inchers.....

It's not the size that counts, it's how big it is!

I once considered building a bike with really big wheels. Chalo Colina, the famous Boeing machinist, knew where to get tyres for it, the key component. It would indeed make mere 29ers "so last week"! Couldn't find anyone reliable to build the frame. Where were these guys when I needed them...

There are a number of new bicycles and bicycle frames coming out that a Rohloff Hub will just pop in and you can adjust the chain freeplay easy, But this is a Thorn Forum and at this time Thorn are not making any 29"er's.

I love 29"er's and have just got a New 29"er last week ($8700 NZ) sorry no Rohloff Hub but it's got Sram's new XO1 (1 by 11) which Sram are going to make for Cyclo X and the Head Man from Sram Europe can to NZ said that they are going to make a set up for Cycle Touring Too!

I have had a Ti On-One (US Made) 29"er with a Rohloff Hub watch I raced for a number of years, it was a great bike but removing the rear wheel was a Big Pain!!!
