Loud Klein Rascal

Think I would end up with a Retrobike lynch mob at my door if I did that!

Sick project, can't wait to see what you do with it.
Try to find another way of holding it in the stand though, that oversized alloy tubing is super-thin-walled, you could easily crush or dent it with the clamp there.
The seat tube (directly below the top-tube) is generally thicker, though the safest method is to bolt the seatpost in and clamp the post itself.

Yep - totally agree. The clamp is very very lightly gripping (just enough to hold it for the pictures). Usually go for seatpost.

Have previously learnt the hard way that tubes aren't designed for that kind of stress!

Race Face cranks look ace on bikes this age. 1x works really well with them if you stick a narrow-wide chainring on.

I don’t think the current thing with wide range cassettes up to 42T or more looks very good on older bikes though. Something like an 11-34 with a single 32 or 34 up front gives you a little bit more range than an old cassette used to but without looking out of place on an older bike. Pick your number of gears, but anything from 9-speed up has great trigger shifters. Retro SRAM looks the best for your £, IMO. Even the current bottom of the range Shimano 3x8 shifts absolutely flawlessly tbh, if you wanted a really budget setup. Frame deserves something a bit more bling - but you know that!

After having this lying around for about a year, I pulled my finger out and finished it over the weekend. I haven't owned a MTB for a pretty long time, and have never used 1 x anything, so wasn't sure if everything was going to work. After yesterday's first outing, I can say that the Rascal is very fun to ride, and the 30 year old XT stuff shifts better than my modern SRAM Red! Ended up going for:

1 x 7 XT M095/M735 group - managed to find some good NOS stuff on ebay
Middleburn RS7/Uno chainset
NOS Dia Compe 987 Cantis
Got an LBS to build some Sun Ringle rims on NOS XT 737/738hubs

Some things I need to look at:

• Shorter stem as will mostly be used for casual city riding (all these retro quills seem very long and the Rascal geo seems quite stretched)
  
• Not sure about the bars
  
• Think the chain line is a bit wrong - have found shorter axles on ebay, but removal of the Klein PF BB concerns me
  
• May need a chain guide? Had no issues dropping off kerbs etc, but seems it might be a good idea anyway? This something I have no prior experience of.
  
  
  

Excellent work! Very nicely modernised but not too much

What a frame, I love how the pink looks even lairier out in natural light. Nice build, it looks a huge amount of fun to ride!

Looks great!

Love it, Ringle stem looks fantastic. One thing, and I'm sure you know this - these frames suffer from the high seat post clamp section cracking and ultimately having to be cut off and a collar used (if possible). "They" say that the way to avoid this is to ensure that you have a decent length of post below the top tube as it were, so the upper section is not resisting the riders weight/the degree to which it is doing so is minimised.

The pink is somehow messing with the exposure/white balance and making it hard to photograph. It's so bright!

Thank a lot - I wasn't aware of this. Pretty sure the Controltech one has a decent length in the frame, but I am going to double check now. Would be heartbroken if I damaged this frame, it has made it through almost 30 years with barely a scratch!

Nice combination of old and new. Perfect.

I'll be honest, I'm quite enjoying the retina burn.

Love this! Mad frame and great component selection.

Terrific!
