Vital MTB: Bike of the Day – Iron Horse Sunday Prototype

On Vital MTB user Simon-Watts won Bike of the Day on 23.1.2013. That’s not too interesting, but the bike he won with is. It’s a 2010 Ironhorse Sunday prototype he won in an ebay auction.

The Ironhorse Sunday is an iconic downhill bike which Sam Hill won quite some races on. In addition the Dave Weagle designed suspension attracted a big enough fanbase so that the bike is seen in bikeparks even nowadays, 7 years after it was introduced to the market. Ironhorse has gone out of business in 2009 but before that they seemed to have been working on a new Sunday without the Dave Weagle designed dw-lnik rear suspension. Simon-Watts’ description:

Produced to replace the DW equipped Sundays when it was realized Ironhorse were loosing the rights to DW. Never produced for obvious reasons, but an exciting design. Lighter than my Medium size Sunday with same components.

Have a look at the pictures posted. It look like a classic four-bar design with an extremly low shock placement. Geometry data would be interesting, especially chain stay length an head angle. The chain stay pivot might be above the axle to circumvent the Specialized patent. Esthetics reminds me a bit of the current Trek Session (which is a good thing). I like it. Or rather “I would have liked it, if it had made it to production…”.

Damper Rod Orientation

I bought my Transition Blindside about a year ago second-hand. The frame was equipped with a Fox Van R shock. It always annoyed me that the rebound adjuster faced upwards to the top tube because it was hardly possible to get a grip on the adjuster.

When I recently serviced my shock I realized that the damper rod orientation can be changed by simply turning the rod! Yes, it’s pretty awkward that I didn’t think of it earlier…

Transition Blindside: New Shock Mounting Hardware

In a recent post on MTBR here Transition Bikes mentioned new shock mounting hardware for their Transition Blindside and Bottlerocket frames. As I have issues with my shock mounting bolts loosening up once in a while on my 2011 Blindside I ordered immediately. The new bolt and flip-chips arrived some weeks later including nice stickers, thanks guys!

On the left the old 4-piece and on the right the new 3-piece shock mounting hardware.
