Barry, the lead and top-rope routes are graded in French sport grade, so there is no such such thing as 5a, 5b & 5c. It goes 5 then 5+, only when you get to 6 does it split up into a, b & c.

I visited TE in August 2008 and found it to be a pretty good gym! My only criticism is that it is lacking in more difficult top rope routes. While it is nice that some walls are dedicated to leading, the visiting climber, or top roper who does not bring his/her own rope to the gym, will have to settle for routes in the 5a-6c range. There was one 7a that was set up for top rope, otherwise if you want to climb 7s, then bring your own rope. I found the vast majority of top rope climbs to be at the 4-5+ level. Tons of bouldering, lots of hard stuff there...

Visited this place a couple of times now and it's pretty nice but there appears to be a serious lack of climbs focused at beginners/intermediate. I've visited LOTS of indoor walls and this place has the least amount of 5ish climbs of any of them. To most of us this may not be a problem but as I'm climbing with someone new they found it incredibly difficult here. The other problem was that all the 5s were labeled 5+ no 5a, 5b, 5c just 5+! And among these were many climbs that were FAR harder than your average 5a (or maybe my long break has made me more out of shape than I thought). Overall though it's your average indoor climbing wall with a good number of climbs and a decent height but if your looking for easier climbs then go elsewhere. I posting this comment in the hope that this is picked up by someone at Transition Extreme who can address this issue. Maybe the guys that work there are all uber climbers but they should consider that not everyone is - go take a look at Vertical World in Dundee and Alien Rock in Edinburgh and see how they cater for us mortals.
